Blood circulation Blood circulation:circulation system is made up of the heart and vessels in which blood is flowing in certain direction ,going round and begin again. 血液循环：心脏和血管组成机体的循环系统，血 液在其中按一定方向流动，周而复始。 Cardiac structure

The function of blood circulation Transport oxygen and nutriment necessary for metabolism to the body and send off the metabolic products. 运送机体代谢活动所必须的氧气和营养物质，运走 代谢产物。 ◆ Maintain the stable state of the internal environment,deliver hormones and body fluid to the target organ to perform humoral regulation 维持内环境的相对稳定，运送激素及体液因素到靶器 官，实现体液调节
