The aorta.

Blood returning from the body systemic circulation first enters which chamber of the heart?
The large artery connected to the heart, called the Aorta.
he is known as 'Father of bolld circulation'. first to explain systemic circulation- pumping of blood from heart and its circulation through the entire body and then the return of the blood to heart
In the pulmonary circulation, deoxygenated blood leaves the right section of the heart through the pulmonary artery, enters the lungs and oxygenated blood comes through the pulmonary veins. The blood then moves to the left atrium of the heart.
I believe the first vessel is the pulmonary trunk which brings the deoxygenated blood to the pulmonary arteries and so on....
the first person to explain the systemic circulation, as well as the details of the blood pumped into the body from the heart
The same blood flowed through the viens and arteries. Nova AnwserHarvey is best-known for the discovery of the Circulation of the Blood!The first "accurate" description of the systemic circulation.(Even though he had to postulate the existence of the capillary beds.)

The answer is Protosystemis ShuntOrdinarily the blood coming away from the digestive tract is kept in a venous network (the "portal" system) separated from from blood that is returning directly to the heart via the vena cava (the "systemic" flow). This portal blood must first be cleaned and detoxified by the liver before merging with systemic venous blood.If there is abnormal flow which permits the "dirty" digestive blood tobypass the liver, it is called a Porto-Systemic "shunt".
Pulmonary circulation is blood supply to the lungs. This is important for two reasons. First, like all organs, the lungs have to have oxygen themselves in order to function. Second, blood has to go through the lungs in order to become oxygenated. The pulmonary vein is the only vein in the body that carries oxygenated blood. Systemic circulation is important for two reasons also. First, and simplest, is the fact that every cell in the body has to have oxygenated blood to function. Without oxygenated blood, the cells will begin to infarct, or die. Second, systemic circulation creates what's called perfusion pressure. Simply put, it's the pressure required to allow the organs to pull the oxygen from the blood. As blood pressure goes down, the body's ability to pull in oxygen from the blood also decreases.
blood circulation was first reported by william harveyin man there is a comlpete separation of venous blood and arterial blood
