脉管系统(Circulatory System)教学课件

1、脉管系统脉管系统 Circulatory System The circulatory system includes cardiovascular system and lymphatic system. They form a tubular system which, with limited exception, is closes and lines throughout with endothelium. (Angiology) The main function served by the circulatory system is transporting materials.

The upper chambers, called the atria, have thin walls and receive blood returning to the heart. The lower chambers, the ventricles, force the blood out of the hear

The arteries increase

6、in mumber by repeated division and also decrease in diameter. 静脉静脉Veins The veins transport blood from capillary networks to the heart. Collective capillaries form small veins. They run towards the heart, receive tributaries one after another, and consequently as a result their vessels widen in diam
