In pulmonary circulation, deoxygenated blood is pumped from the heart's right ventricle, while in systemic circulation, oxygenated blood is pumped from the heart's left ventricle.
- Pulmonary circulation is a vascular system between the heart and the lungs for blood flow through the lungs.
- Pulmonary circulation initiates by pumping deoxygenated blood by the right ventricle which is then transported to the lungs where this blood is oxygenated to reenter the heart in the left atrium.
- The main function of the pulmonary circulation is to exchange gases (CO2 and O2) between the blood and the air.
- Systemic circulation is a vascular system that transports blood from the left ventricle to all the tissues of the body.
- The systemic circulation is responsible to maintain a constant blood flow through the capillaries which aims to promote nutrient diffusion.
In conclusion, in pulmonary circulation, deoxygenated blood is pumped from the heart's right ventricle, while in systemic circulation, oxygenated blood is pumped from the heart's left ventricle.
