The pulmonary circuit delivers blood to and from while the systemic circuit delivers blood to and from

1- all organs above the heart including the brain; all organs below the body including the kidneys and liver

2- the tissues of the body; the lungs

3- all organs below the body including the kidneys and liver; all organs above the heart including the brain

4- the lungs; the tissues of the body.

The pulmonary circuit delivers blood to and from the lungs while the systemic circuit delivers blood to and from the tissues of the body.

Pulmonary circuit or circulation is a system of blood vessels between the heart and the lungs. In pulmonary circulation, deoxygenated blood leaves from the heart’s right ventricle through the pulmonary artery to the lungs. Oxygenated blood from the lungs (CO2 is released andO2 is picked up during respiration) is transported through the pulmonary vein and returned to the left atrium of the heart.

System circulation than transports oxygenated blood from the heart’s left ventricle through the aorta and to the rest of the body. Oxygen-poor blood from  all tissues is then returned through the veins back to heart.

the answer is 1. photosynthesis. glad to

the tricuspid valve is present between right atrium and right ventricle
