A-- Aorta

B-- Pulmonary veins

C-- Pulmonary artery

D-- Interior vena cava

Functions of Aorta:-

The aorta is the main artery that carries blood away from your heart to the rest of your body. After the blood leaves the heart through the aortic valve, it travels through the aorta, making a cane-shaped curve that connects with other major arteries to deliver oxygen-rich blood to the brain, muscles, and other cells.The aorta is the largest artery in the body. The aorta begins at the top of the left ventricle, the heart's muscular pumping The aorta is the largest artery in the body. It carries oxygen-filled blood from the heart to different organs in the body.

Functions of Pulmonary veins:-

The pulmonary veins are the veins that transfer oxygenated blood from the lungs to the heart. The largest pulmonary veins are the four main pulmonary veins, two from each lung that drain into the left atrium of the heart. The pulmonary veins are part of the pulmonary circulation.The pulmonary veins play an essential role in respiration, by receiving blood that has been oxygenated in the alveoli and returning it to the left atrium.

Functions of Pulmonary artery:-

The pulmonary arteries are the two major arteries coming from the right ventricle of the heart. This lower chamber of the heart contains blood that is low in oxygen. The pulmonary arteries carry this blood to the lungs. There, the blood picks up more oxygen and releases carbon dioxide.A pulmonary artery is an artery in the pulmonary circulation that carries deoxygenated blood from the right side of the heart to the lungs. The largest pulmonary artery is the main pulmonary artery or pulmonary trunk from the heart, and the smallest ones are the arterioles, which lead to the capillaries that surround the pulmonary alveoli.

Functions of interior vena cava:-

The inferior vena cava (or IVC) is a large vein that carries the deoxygenated blood from the lower and middle body into the right atrium of the heart. It is formed by the joining of the right and the left common iliac veins, usually at the level of the fifth lumbar vertebra.The inferior vena cava is the lower ("inferior") of the two venae cavae, the two large veins that carry deoxygenated blood from the body to the right atrium of the heart: the inferior vena cava carries blood from the lower half of the body whilst the superior vena cava carries blood from the upper half of the body. Together, the venae cavae (in addition to the coronary sinus, which carries blood from the muscle of the heart itself) form the venous counterparts of the aorta.
