Answers
Explanation:
Human blood circulation is responsible for the transport of nutrients and oxygen to the different parts of the body. Oxygen-rich blood travels through the pulmonary vein and the left atrium into the left ventricle. So, the partial pressure of oxygen will be very high. The pulmonary artery carries the deoxygenated blood from the right ventricle of the heart to the lungs. Since, the blood is deoxygenated, the blood will have more partial pressure of carbon dioxide than oxygen. Aorta carries the oxygen rich blood from the left side of the heart to the body. The vena cava is responsible for carrying the doxygenated blood from the lower and middle parts of the body to the right atrium. The partial pressure of carbon dioxide in vena cava or veins is equal to 45 mm Hg. The partial pressure of oxygen in arterial blood is equal to 100 mm Hg.

Explanation:
the human body is a complex machine, requiring many processes to function efficiently. To keep these crucial processes running without any hitches, vital elements and components need to be delivered to the various parts of the body.
This role of transportation is undertaken by the human circulatory system, moving essential nutrients and minerals throughout the body and metabolic waste products away from the body. Below is the neat labelled Circulatory system diagram.
