空肠和回肠之间并无明显界限,在形态和 结构上的变化是逐渐改变的。


大肠 大肠large intestine是消化管最后的一段, 长约1.5米,起自右髂窝,终于肛门,可分 为盲肠、结肠和直肠三段。大肠的主要机 能是吸收水分,将不消化的残渣以粪便的 形式排出体外。


盲肠cecum是大肠的开始部(图2-22), 位于右髂窝内,左接回肠,上通升结肠。 在盲肠的后内壁伸出一条细长的阑尾 vermiformappendix,其末端游离,一般长 6-8厘米,内腔与盲肠相通,它是盲肠末 端在进化过程中退化形成的。






成人骨:206块,依其存在部位可分为颅骨、 躯干骨和四肢骨。 一、骨: 1.骨的形状 : 按其形态特点可概括为下列四种 (一)长骨long bone (二)短骨 short bone (三)扁骨flat bone (四)不规则骨irregular bone

2、功能: 首要的功能体重和内部器官以及 维持体姿。 第三个功能是保护。


胆汁: 从肝管出肝后并不立即直接流入十 二指肠,而是首先贮存于胆囊内,间断 性地排放入十二指肠。 胆汁流入十二指肠前在肝外流经的管道 总称为肝外胆道系统,包括肝管、肝总 管、胆囊管、胆囊和胆总管(图2-27)。






胰pancreas是人体的第二大腺(图221),横跨在第1、2腰椎的前面,质地柔软, 呈灰红色。 胰由外分泌部和内分泌部两部分组成,外 分泌部的腺细胞分泌胰液,经各级导管, 流入胰腺管,胰腺管与胆总管共同开口于 十二指肠。 胰液中含有多种消化酶,对消化食物起重 要作用。 内分泌部是指散在于外分泌部之间的细胞 团——胰岛,它分泌的激素直接进入血液 和淋巴,主要参与糖代谢的调节。

医学英文知识点总结

医学英文知识点总结1. Anatomy and PhysiologyAnatomy is the study of the structure and shape of the human body, while physiology is the study of how the body functions. Understanding of the human body's structure and function is essential for healthcare providers, as it informs their diagnosis and treatment of medical conditions.2. Cellular BiologyCellular biology is the study of cells, their structure, function, and interactions with one another. This knowledge is fundamental in understanding the mechanisms of disease, as many conditions stem from abnormalities in cellular processes.3. BiochemistryBiochemistry is the study of the chemical processes that occur within living organisms. Understanding biochemical pathways and the role of specific molecules in the body is crucial for diagnosing and treating metabolic diseases.4. PharmacologyPharmacology is the study of how drugs affect the body and vice versa. Healthcare providers need to have a solid understanding of pharmacology to select appropriate medications, determine dosages, and predict potential drug interactions or adverse effects.5. PathophysiologyPathophysiology is the study of how diseases and disorders alter the normal physiological processes of the body. Healthcare providers must understand the underlying mechanisms of diseases to make accurate diagnoses and develop effective treatment plans.6. Medical EthicsMedical ethics is the moral principles that guide the conduct of healthcare professionals in their practice. Understanding the ethical considerations of patient care, research, and public health is essential for ensuring the well-being and autonomy of patients.7. EpidemiologyEpidemiology is the study of the distribution and determinants of health-related states or events in specific populations. Healthcare providers use epidemiological data to identify patterns of disease, assess risk factors, and develop strategies for disease prevention and control.8. Medical History TakingTaking a thorough and accurate medical history is essential in diagnosing and treating patients. Healthcare providers must ask targeted questions to gather information about a patient's symptoms, medical history, family history, and social history.9. Physical ExaminationConducting a systematic and comprehensive physical examination is essential for assessing a patient's overall health. Healthcare providers must be proficient in techniques such as inspection, palpation, percussion, and auscultation to identify abnormalities and make accurate diagnoses.10. Diagnostic TestingInterpreting diagnostic tests such as blood work, imaging studies, and electrocardiograms is essential for diagnosing and monitoring medical conditions. Healthcare providers must understand the indications for specific tests, their limitations, and the interpretation of results.11. Clinical Decision MakingClinical decision making involves synthesizing patient information, medical knowledge, and available evidence to make informed choices about patient care. Healthcare providers must weigh the risks and benefits of treatment options and involve patients in shared decision making.12. Patient CommunicationEffective communication with patients is essential for building trust, conveying information, and involving patients in their care. Healthcare providers must use clear, empathetic, and culturally sensitive communication to ensure patient understanding and engagement.13. Patient EducationPatient education is crucial for empowering patients to manage their health and participate in treatment decisions. Healthcare providers must provide relevant information about medical conditions, treatment options, lifestyle modifications, and self-care strategies. 14. Preventive MedicinePreventive medicine aims to reduce the incidence and impact of disease through health promotion, disease prevention, and early detection. Healthcare providers must understand risk factors, screening guidelines, and immunization schedules to promote primary and secondary prevention.15. Interprofessional CollaborationInterprofessional collaboration involves working with other healthcare professionals to optimize patient care. Healthcare providers must effectively communicate, coordinate care, and respect each other's expertise to achieve positive patient outcomes.16. Patient SafetyPatient safety involves addressing the risks, errors, and harm in healthcare to prevent adverse events and promote a culture of safety. Healthcare providers must implement strategies to improve medication safety, prevent healthcare-associated infections, and reduce diagnostic errors.17. Quality ImprovementQuality improvement involves systematic efforts to enhance the effectiveness, efficiency, and safety of healthcare delivery. Healthcare providers must use data-driven approaches to identify and address opportunities for improvement in patient care.18. Global HealthGlobal health focuses on improving health and achieving equity in health for all people worldwide. Healthcare providers must understand the social, economic, and environmental determinants of health to address global health challenges such as infectious diseases, non-communicable diseases, and health disparities.19. Medical ResearchMedical research aims to advance knowledge in healthcare and improve patient outcomes. Healthcare providers must understand research methodology, scientific evidence, and ethical considerations to critically appraise research findings and apply them to practice.20. Healthcare PolicyHealthcare policy involves the development and implementation of regulations, laws, and programs to improve the delivery, quality, and cost-effectiveness of healthcare. Healthcare providers must understand healthcare policy to advocate for patients, promote health equity, and address healthcare disparities.In conclusion, a comprehensive understanding of medical knowledge points is essential for healthcare providers to provide high-quality, safe, and effective care to patients.

3.体腔(body cavity) The human body has two major cavities: the dorsal cavity and the ventral cavity. Each is subdivided into smaller cavities, within which specific visceral organs are located. The dorsal cavity contains the cranial cavity and the spinal cavity. The brain is in the cranial cavity, and the spinal cord is in the spinal cavity. The ventral cavity is divided by the diaphragm into the thoracic cavity and the abdominopelvic cavity .The heart and lungs are in the thoracic cavity, and most other internal organs are in the abdominopelvic cavity. Membranes divide the thoracic cavity into the pleural cavities, containing the right and left lungs ,and the pericardial cavity, containing the heart. The abdominopelvic cavity has two portions: the upper abdominal cavity and the lower pelvic 22 cavity.
