  The muscular system allows the body to move, and its contractions produce heat, which helps maintain a constant body temperature. Striated muscles条纹肌 can be consciously controlled. The ends of these muscles are attached to different bones by connective tissue结缔组织 bands so that when the muscle contracts, one bone moves in relation to the other. This makes it possible to move the whole body, as when walking, or to move just one part of the body, as when bending a finger.

肌肉系统允许人体活动/使人体活动。肌肉收缩产生保持人体体温的热量。条纹肌可以被有意识的控制。这些肌肉的末端通过结缔组织附着于不同的骨,当肌肉收缩时,骨与骨之间就会相继/连带活动。这就使得全身活动成为可能,比如走路。或者仅仅活动人体的一部分,比如弯曲一根手指。

Contractions of the heart and smooth muscles平滑肌 are not under conscious control. Smooth muscles are found in the walls of organs such as the stomach and the intestines肠子 and serve to move the contents of these organs through the body.

心脏收缩和平滑肌收缩则不受有意控制。平滑肌存在于各器官壁内层,例如在胃壁和肠壁。同时,把胃肠中的物质运送至全身。

The circulatory system. All parts of the body must have nourishment and oxygen in order to function and grow, and their waste products must be removed before they accumulate and poison the body. The circulatory system distributes needed materials and removes unneeded ones. It is made up of the heart, blood vessels, and blood, which together make up the cardiovascular system. The blood is also part of the body’s defense system. It has antibodies抗体 and white blood cells that protect the body against foreign invaders.

循环系统。人体的各个部分都需要养分和氧气来发挥功能和生长。同时,必须在他们所产生的废物聚积进而危害生命之前将其排除体外。循环系统运送有益物质,排除废物。心血管系统是循环系统之一;它由心脏,血管和血液共同构成。血液也是人体防御系统的一部分。血液中含有保护人体不受外来侵略的抗体和白细胞

The heart is a muscle that is divided into two nearly identical halves: one half receives blood from the lungs and sends it to the rest of the body, the other half sends blood that has traveled through body back to the lungs. When the heart muscle contracts, the blood is forced out into arteries and enters small capillaries毛细血管. Blood returns to the heart through veins静脉.

心脏是一块几乎被分为对等两半的肌肉。一半吸收来自肺部的血液,并将其输送到人体的其余部位。另一半使流经全身的血液回流至肺部。当心脏收缩时,动脉将血液输送到毛细血管,静脉将血液输送回心脏。

Also functioning in circulation is the lymphatic淋巴的 system. Some of the fluid that surrounds cells does not reenter the blood vessels directly. This fluid, called lymph淋巴, returns to the heart by way of another system of channels------the lymph vessels. Lymph nodes淋巴结 along these vessels filter the fluid before it reenters the blood. The spleen is a large lymphatic organ that filters the blood.

淋巴系统也是循环系统的组成之一。一些细胞周围的液体没有直接回流至血管。这种液体称为淋巴液,通过另一个管道系统------淋巴管道回流至心脏。淋巴液在被沿淋巴管的淋巴结过滤之后进入血液。脾是一个过滤血液的大淋巴器官。
