The left atrium and left ventricle are the 2 chambers of the heart that are involved in systemic circulation.
Systemic circulation begins and ends at the left side of the heart, in the left atrium and left ventricle.
The ventricles are the discharging chambers for the blood. The left pumps blood through the systemic circulation, and the right through the pulmonary circulation.
The right atrium receives blood from the systemic circulation. It then assists in filling the right ventricle.
The heart is made up of four chambers. Two atria (top half) and two ventricles (bottom half) The right atrium receives unoxygenated blood from the body and pushes it into the right ventricle. The right ventricle then pumps the unoxygenated blood to the lungs where it is oxygenated. The left atrium then receives this newly oxygenated blood from the lungs and pushes it into the left ventricle which then sends the blood (with lots of oxygen for the body to use) to the rest of the body. The blood from the body then returns to the right atrium and the cycle starts all over again.
The ventricles are responsible for pumping the blood. Basically, think of the atria as receiving points and the ventricles as the powerhouses of the heart, all pumping in a steady rhythm.
Pulmonary and systemic
systemic circulation - BETWEEN the heart and lungs
the systemic systemic circulation
coronary circulation
In the left atrium it begins and ends. :D vice versa for systemic circulation.
The systemic circulation includes three parts. The coronary circulation, the hepaticportal circulation and the renal circulation
