心脏是一个中空的肌性器官，位于胸腔的中部，由一间隔分为左右两个腔室，每个腔室又分为位于上部的心房和下部的心室两部分。心房收集入心血液，心室射血出心。心室的进口和出口都有瓣膜，保证血液单向流动。人体在不同的生理状况下，各器官组织的代谢水平不同，对血流量的需要也不同。心血管活动能在机体的神经和体液调解下，改变心排血量和外周阻力，协调各器官组织之间的血流分配，以满足各器官组织对血流量的需要。The heart is a hollow muscular organ located in the middle of the thoracic cavity and divided into left and right chambers by a septum, and each chamber is further divided into two parts, the atrium in the upper part and the ventricle in the lower part. The atria collect blood into the heart and the ventricles eject blood out of the heart. The ventricles have valves at the inlet and outlet, which keep blood flowing in one direction. Under different physiological conditions of the human body, the metabolic levels of various organs and tissues are different, and the needs for blood flow are also different. Cardiovascular activity can change cardiac output and peripheral resistance under the mediation of the body's nerves and body fluids, and coordinate the distribution of blood flow among various organs and tissues to meet the needs of various organs and tissues for blood flow.
