Inhaled air passes into the throat, or pharynx(咽), where it mixes with air that enters through the mouth and also with food destined for the digestive tract. The pharynx is divided into three regions: (1) an upper portion, the nasopharynx(鼻咽), behind the nasal cavity;(2) a middle portion, the oropharynx(口咽), behind the mouth; and (3) a lower portion, the laryngeal pharynx(喉咽), behind the larynx. The palatine tonsils(腭扁桃体) are on either side of the soft palate(软腭) in the oropharynx; the pharyngeal tonsils, or adenoids(咽扁桃体 ), are in the nasopharynx.

呼吸系统介绍作文英文

呼吸系统介绍作文英文英文：The respiratory system is a vital part of the human body, responsible for taking in oxygen and expelling carbon dioxide. It consists of the nose, mouth, throat, larynx, trachea, bronchi, and lungs. When we breathe in, air enters through the nose or mouth and travels down the throat into the trachea, which then branches into the bronchi and eventually reaches the lungs. In the lungs, the oxygen is transferred to the blood, while carbon dioxide is removed from the blood and exhaled.The respiratory system also plays a role in producing sound, as air passing through the larynx enables us to speak and produce different vocal sounds. It's amazing how our body can perform such complex functions without us even thinking about it. For example, when I'm running, my breathing becomes faster and deeper to supply my muscles with more oxygen. It's like my body knows exactly what itneeds to do to keep me going.中文：呼吸系统是人体的一个重要部分，负责吸入氧气并排出二氧化碳。

介绍呼吸系统英文作文

介绍呼吸系统英文作文英文回答：The respiratory system is an essential part of our body that allows us to breathe and take in oxygen while getting rid of carbon dioxide. It consists of several organs, including the nose, throat, trachea, bronchi, and lungs.Firstly, the process of breathing starts with the nose. When we inhale, air enters through the nostrils and passes through the nasal cavity. The nose helps to filter, warm, and moisten the air before it reaches the lungs. It also contains tiny hairs called cilia that trap dust and other particles, preventing them from entering the respiratory system.After passing through the nose, the air travels down the throat, also known as the pharynx. The pharynx serves as a common passage for both air and food. When we swallow, a flap called the epiglottis covers the opening to thetrachea, ensuring that food goes down the esophagus and not the windpipe.The trachea, or windpipe, is a tube that connects the throat to the bronchi. It is lined with tiny hair-like structures called cilia, which help to move mucus and trapped particles out of the respiratory system. The trachea then splits into two bronchi, with each bronchus leading to one lung.Inside the lungs, the bronchi continue to branch out into smaller tubes called bronchioles. At the end of the bronchioles are tiny air sacs called alveoli. These alveoli are surrounded by blood vessels and are the site of gas exchange. Oxygen from the air enters the bloodstream while carbon dioxide, a waste product, is expelled from the body through exhalation.The respiratory system also plays a role in speech production. The vocal cords, located in the larynx or voice box, vibrate as air passes through, producing sound. The sound is then shaped into words by the movement of thetongue, lips, and other articulators.In summary, the respiratory system is responsible for the process of breathing and gas exchange. It allows us to take in oxygen and expel carbon dioxide, ensuring that our body has enough oxygen for various physiological functions.中文回答：呼吸系统是我们身体的一个重要部分，它使我们能够呼吸并吸入氧气，同时排出二氧化碳。

呼吸系统英文作文

呼吸系统英文作文The respiratory system is essential for our survival.It allows us to take in oxygen and expel carbon dioxide, which is crucial for the functioning of our cells.When we inhale, air enters through our nose or mouthand travels down the trachea into the lungs. The lungs are made up of tiny sacs called alveoli, where the exchange of oxygen and carbon dioxide takes place.The diaphragm is a key muscle in the respiratory system. When we inhale, the diaphragm contracts and moves downward, creating more space in the chest cavity for the lungs to expand. When we exhale, the diaphragm relaxes and moves upward, pushing air out of the lungs.The respiratory system works closely with thecirculatory system. Oxygen from the lungs is carried by the blood to all the cells in the body, while carbon dioxide is picked up from the cells and transported back to the lungsto be exhaled.The respiratory system can be affected by various diseases and conditions, such as asthma, chronicobstructive pulmonary disease (COPD), and pneumonia. It's important to take care of our respiratory health by avoiding smoking, staying active, and seeking medical attention if we experience any breathing difficulties.In conclusion, the respiratory system plays a vitalrole in our overall health and well-being. It's responsible for supplying oxygen to the body and removing waste gases, allowing us to breathe and live. We should appreciate and take care of our respiratory system to ensure a healthy and fulfilling life.。

呼吸系统英语作文

呼吸系统英语作文Breathing is a fundamental biological process that is essential for sustaining life. The respiratory system, which is responsible for this vital function, is a complex and intricate network of organs and structures that work together to ensure the efficient exchange of gases between the body and the environment. In this essay, we will delve into the intricacies of the respiratory system, exploring its anatomy, physiology, and the various mechanisms involved in the process of breathing.The respiratory system is composed of the upper respiratory tract and the lower respiratory tract. The upper respiratory tract includes the nose, nasal cavities, pharynx, and larynx, while the lower respiratory tract consists of the trachea, bronchi, bronchioles, and the alveoli within the lungs. Each of these components plays a crucial role in the overall functioning of the respiratory system.The process of breathing begins with the inhalation of air through the nose or mouth. The air then travels through the upper respiratory tract, where it is warmed, humidified, and filtered of impurities. The air then enters the lower respiratory tract, where it reaches the alveoli, the tiny air sacs located within the lungs. It is inthe alveoli that the exchange of gases takes place, with oxygen being absorbed into the bloodstream and carbon dioxide being expelled from the body.The mechanics of breathing are controlled by the diaphragm and the intercostal muscles, which work together to expand and contract the thoracic cavity. During inhalation, the diaphragm contracts, causing the thoracic cavity to expand and the lungs to fill with air. Conversely, during exhalation, the diaphragm relaxes, and the intercostal muscles contract, causing the thoracic cavity to decrease in volume and the lungs to expel the air.The respiratory system is not only responsible for the exchange of gases but also plays a vital role in the regulation of the body's pH levels. The lungs are responsible for the removal of carbon dioxide from the body, which is a byproduct of cellular respiration. When carbon dioxide levels in the blood increase, the body's pH levels decrease, leading to a condition known as acidosis. The respiratory system responds to this by increasing the rate and depth of breathing, which in turn increases the removal of carbon dioxide from the body and helps to restore the body's pH balance.In addition to its primary function of gas exchange, the respiratory system also plays a crucial role in the body's immune response. The upper respiratory tract is lined with specialized cells that producemucus, which traps and removes foreign particles and pathogens from the air before they can enter the lower respiratory tract. The lungs also contain specialized immune cells, such as macrophages and lymphocytes, which help to defend the body against respiratory infections and other respiratory diseases.Despite the remarkable efficiency of the respiratory system, it can be susceptible to a variety of diseases and disorders. Conditions such as asthma, chronic obstructive pulmonary disease (COPD), lung cancer, and pneumonia can all have a significant impact on the respiratory system's ability to function effectively. These conditions can be caused by a variety of factors, including genetic predisposition, environmental exposures, and lifestyle choices, such as smoking.In conclusion, the respiratory system is a complex and essential component of the human body, responsible for the vital process of gas exchange and the regulation of the body's pH levels. Its intricate anatomy and physiology allow it to perform these critical functions with remarkable efficiency, but it is also susceptible to a range of diseases and disorders that can have a significant impact on overall health and well-being. Understanding the workings of the respiratory system is crucial for maintaining good respiratory health and for developing effective treatments for respiratory diseases.。

介绍呼吸系统英文作文

介绍呼吸系统英文作文英文回答：The Respiratory System.The respiratory system is a complex network of organs and tissues that work together to bring oxygen into the body and remove carbon dioxide. The main organs of the respiratory system are the lungs, which are located in the chest cavity. The lungs are made up of millions of tiny air sacs called alveoli, which are lined with capillaries. Oxygen from the air diffuses across the alveoli and into the capillaries, where it is picked up by the bloodstream. Carbon dioxide from the bloodstream diffuses across the alveoli and into the air, which is then exhaled.The respiratory system is controlled by the respiratory center in the medulla oblongata of the brain. The respiratory center sends signals to the muscles of the diaphragm and the intercostal muscles, which cause thelungs to expand and contract. The rate and depth of breathing is controlled by the respiratory center in response to changes in the body's oxygen and carbon dioxide levels.The respiratory system is essential for life. Without oxygen, the body cannot function properly. Carbon dioxide can also be harmful to the body if it is not removed. The respiratory system works tirelessly to ensure that the body has a constant supply of oxygen and that carbon dioxide is removed.中文回答：呼吸系统。

呼吸系统-英文版

The respiratory system can be divided into two parts: The upper respiratory tracts:mouth, nose & nasal cavity,pharynx and larynx The lower respiratory tracts:trachea,bronchi,bronchioles,alveoli,diaphragm
When you breathe, the air: enters the body through the nose or the mouth travels down the throat through the larynx (voice box) and trachea (windpipe) goes into the lungs through tubes called main-stem bronchi one main-stem bronchus leads to the right lung and one to the left lung in the lungs, the main-stem bronchi divide into smaller bronchi and then into even smaller tubes called bronchioles bronchioles end in tiny air sacs called alveoli
Diaphragm located below the lungs, attaching to the lower ribs, sternum and lumbar spine and forming the base of the thoracic cavity, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs. Upon exhalation, the diaphragm relaxes and returns to its domelike shape, and air is forced out of the lungs.

呼吸系统英语作文

呼吸系统英语作文The respiratory system is a fascinating and essential aspect of the human body, responsible for facilitating the exchange of gases that sustain life. It is a complex network of organs and structures that work in harmony to ensure the efficient intake of oxygen and expulsion of carbon dioxide. The intricate mechanisms involved in this process are a testament to the remarkable engineering of the human body.At the forefront of this system lies the nasal cavity, serving as the entry point for air. The nasal passages are lined with a mucous membrane and hair-like projections called cilia, which act as filters, trapping dust, pollutants, and other harmful particles before they can reach the delicate tissues of the lungs. The air then travels through the pharynx, a shared pathway for both the respiratory and digestive systems, before reaching the trachea, a sturdy, cylindrical tube reinforced by cartilaginous rings.The trachea branches into two primary bronchi, each leading to one of the lungs. These vital organs, encased within the thoracic cavity, are composed of spongy, elastic tissues that facilitate the exchange of gases. The bronchi further divide into a network of smallerbronchioles, ultimately culminating in the alveoli, the tiny, grape-like structures where the actual gas exchange occurs. The alveoli are surrounded by a dense network of capillaries, providing a vast surface area for the diffusion of oxygen and carbon dioxide between the lungs and the bloodstream.Breathing, the rhythmic process that drives the respiratory system, is controlled by a specialized region in the brain called the respiratory center. This center monitors the levels of oxygen and carbon dioxide in the blood and initiates the appropriate respiratory response. During inhalation, the diaphragm, a dome-shaped muscle at the base of the lungs, contracts, increasing the volume of the thoracic cavity and creating negative pressure that draws air into the lungs. Conversely, during exhalation, the diaphragm relaxes, and the elastic recoil of the lungs, combined with the contraction of the intercostal muscles, expels the air from the lungs.The respiratory system is not only crucial for respiration but also plays a vital role in other bodily functions. Speech, for instance, relies on the controlled expulsion of air from the lungs, allowing us to articulate words and communicate effectively. Additionally, the respiratory system aids in regulating the body's pH balance by exhaling carbon dioxide, a byproduct of cellular respiration.Despite its remarkable efficiency, the respiratory system is vulnerableto various environmental and lifestyle factors. Air pollution, smoking, and certain occupational exposures can significantly impair lung function and increase the risk of respiratory diseases such as asthma, chronic obstructive pulmonary disease (COPD), and lung cancer. Maintaining a healthy lifestyle, practicing regular exercise, and avoiding exposure to harmful substances are essential steps in preserving the integrity of this vital system.In conclusion, the respiratory system is a marvel of biological engineering, orchestrating the delicate dance of gas exchange that sustains life. Its intricate mechanisms, from the nasal cavity to the alveoli, work in perfect harmony to ensure the efficient intake of oxygen and expulsion of carbon dioxide. As we breathe in and out, we can appreciate the remarkable complexity of this system and the vital role it plays in our overall well-being.。
