基础医学英语-循环系统功能讲解

尽管循环系统有多种功能，其可分成两种 基本的功能。
Our group will explain the first functions of the circulatory system
Para. 9
Transportation of the substance necessary to maintain cellular metabolism is one of two main functions of the circulatory system. 运输维持细胞新陈代谢所必需的物质是循 环系统主要的两大功能之一。 Substance Maintain 物质 维持
由细胞产生的过量的水、离子、
血浆和代谢废物经过肾毛细血 管滤出。
From there wastes enter the kidney tubes and are excreted in urine.
通过肾毛细血管的 代谢废物进入肾小 管和通过尿液排出。
Para.12
The circulatory system is also responsible for the transportation of hormones through the blood stream. This contributes to the regulatory process of maintaining health of the endocrine system. 循环系统还通过血液运送激素，帮助维持内分泌 系统健康的调节过程。
While the circulatory system has numerous functions，the various capabilities and functions of this intense system can be segregated into two basic responsibilities。
4. hemoglobin
5. phagocytosis
[ ] 血红蛋白
[ ] 噬菌作用
Para. 8
The circulatory system is not a stand alone system，and it requires the assistance of systems such as the respiratory，urinary， endocrine，digestive，and integumentary system in order to maintain its proper function and give the body the life sustenance it requires to life. 循环系统不是独立系统，需要诸如呼吸、泌尿、 内分泌、消化和皮肤等辅助系统来保证其正常 功能，供给人体所需的营养。
当细胞将送达的氧气使用完毕时，它们产生的二 氧化碳会被运回肺并随着呼出的气体被排出。 Carbon dioxide
Expel Exhale
二氧化碳
驱逐，逐出 呼出，发出
Para. 10 The blood and lymph vessel conjunction with the digestive system in order for the circulatory system to perform the delivery of nutrition. 血管和淋巴管与消化系统协同工作以 确保循环系统发挥运用养分的作用
Metabolism
新陈代谢
In conjunction with the respiratory system, red blood cells by the name of erythrocytes are responsible for the transportation of oxygen which is systematically delivered to the cells waiting throughout the body. 结合呼吸系统，红细胞负责将氧有组织地递 送到遍布全身的需氧细胞中。
Unit 4 The Circulatory System
Functions of the system (para.8—15)
Understanding the words
1. ventricle 2. hormone 3. pulmonary [ ] 心室 [ ] 激素 [] 肺部的(有…的属性)
Once the cells have used the oxygen which has been delivered, the carbon dioxide they have produced are then transported back to the lungs and expelled in exhaled air.

Cleansing
净化
When food is eaten it is broken down by the digestive system and the nutrients are absorbed through the wall of the intestines，which is then picked by the blood vessel and carried off to the cells requiring the nutrition with a pit stop throng the liver for nutrient absorption and toxic cleaning.
In conjunction with
The respiration system Systematically
结合
呼吸系统 系统地，有组织地
In the lungs, the oxygen molecules attach themselves to hemoglobin molecules, which reside within the erythrocytes, and then make their way via transport by these cells to cells in need of oxygen. 在肺中，氧分子将自己吸附在驻留在红细胞上的 血红蛋白分子上，然后传递氧气在细胞与细胞之 间前进。 Oxygen molecules Hemoglobin molecules 氧分子 血红蛋白

吃下的食物在消化系统分解，养分通过肠壁吸 收后为血管获取并送到需要这些养分的细胞， 期间肝脏将营养物质吸收并清除有毒物质。
Para. 11
The wastes associated with excess waters, ions, plasma, and metabolic waste produced by the cells, are then filtered through capillaries which belong to the kidneys.
