Step-by-step explanation:
The four chambers of the heart are the right atrium, right ventricle, left atrium, and left ventricle. The right atrium receives deoxygenated blood from the body and pumps it into the right ventricle. The right ventricle then pumps the deoxygenated blood into the lungs, where it receives oxygen and releases carbon dioxide. The oxygenated blood then returns to the left atrium through the pulmonary vein. The left atrium pumps the oxygenated blood into the left ventricle, which then pumps it out to the rest of the body through the aorta.
Oxygen enters the bloodstream in the lungs, where it diffuses across the alveoli walls and into the pulmonary capillaries. Carbon dioxide leaves the bloodstream in the lungs, where it diffuses across the alveoli walls and into the air.
Arteries are blood vessels that carry oxygenated blood away from the heart to the body's tissues. Capillaries are the smallest blood vessels in the body and are responsible for exchanging oxygen and carbon dioxide, as well as other nutrients and waste products between the blood and the body's tissues. Veins are blood vessels that carry deoxygenated blood back to the heart.
Urea is a waste product of protein metabolism and is formed in the liver. It is added to the bloodstream in the liver and removed from the bloodstream in the kidneys through the process of urine formation.
Glucose enters the bloodstream from the small intestine after being absorbed from food, and it leaves the bloodstream as it is taken up by cells for energy production or storage.
