Human Circulatory System

Hi student friends all, this time we are learning about the human circulatory system. Semuakan friends know, that the blood in our body constantly pumped by the heart and transmitted or distributed throughout the body kuta. Well let's look at the human circulatory system was how the heck?

Human circulatory system is a closed circulation and duplicate. Why so? Thus, the meaning of "closed" here is blood transported and circulated throughout the body in the blood vessels. Then the "duplicate" means the one-time circulation, blood enters the heart 2 times.

Human Circulatory System

Circulatory duplicate is composed of small and large blood circulation.

Circulatory system
Blood circulation in the lungs (small circulation)
It says little circulation because, only circulation from the heart to the lungs. So the CO2 containing blood from the right heart chambers entered through the pulmonary artery into the lungs by the pulmonary vein was brought back to the left atrium of the heart. Blood in the left atrium of heart already contains O2

Blood flow scheme as follows:

The right ventricle of the heart - the pulmonary arteries - lungs - pulmonary vein - left atrium of heart

The circulatory system (systemic circulation) is the circulatory system that carries blood that carries blood from the heart throughout the body. Blood coming out of the heart of a lot of oxygen.

mechanism of blood flow as follows:

Left ventricle - aorta - the artery superior and inferior - the cells / tissues of the body - the inferior and superior vena cava - right atrium of the heart
