Write the functions of the following :
a) Pulmonary Vein
b) Aorta
c) Pulmonary Arteries
d) Vena Cava
Answers
Pulmonary Artery:
The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs. The blood here passes through capillaries adjacent to alveoli and becomes oxygenated as part of the process of respiration.
Aorta:
Aorta is the main and largest artery in the human body. The aorta supplies all of the systemic circulation, which means that the entire body, except for the respiratory zone of the lung, receives its blood from the aorta.
Pulmonary Vein:
Pulmonary veins are responsible for carrying oxygenatedblood from the lungs back to the left atrium of the heart. This differentiates the pulmonary veins from other veins in the body, which are used to carry deoxygenated blood from the rest of the body back to the heart.
Vena Cava:
The inferior vena cava is a vein. It carries deoxygenated blood from the lower half of the body to the right atrium of the heart. The corresponding vein that carries deoxygenated blood from the upper half of the body is the superior vena cava.

Have a nice day :)

(a) ...
Pulmonary vein tranfers oxygenated blood from Lungs to the heart.
(b) ...
Arota is the largest artery in the body.
The heart pumps blood from the left Ventricle into the Arota through the Arotic valve.
(c) ...
Pulmonary Artery tranfers deoxygeneted blood from the right side of heart to the lungs.
(d) ...
Vena cava is the largest Vein in the body.
It carries deoxygenated blood from the lower half of the body to the right Atrium.
