In mathematics, mean has several different definitions depending on the context. In probability and statistics, mean and expected value are used synonymously to refer to one measure of the central tendency either of a probability distribution or of the random variable characterized by that distribution.
Red Blood Cell Route through the Cardiovascular System. Let us follow a single red blood cell (RBC) through one full cycle along the circulatory pathway Remember that RBCs carry oxygen throughout the body.Since the blood travels endlessly, an arbitrary choice must be made of a starting point to describe the RBC's route.. The RBC is then pumped through the pulmonary valve into the pulmonary artery and on to the lungs. There the RBC gives off carbon dioxide and picks up oxygen. 4. The RBC returns to the heart through a pulmonary vein, enters the left atrium, passes through the mitral valve, and flows into the left ventricle. 5.
The bloody containing the oxygenated red blood cells is then pumped through the pulmonary vein, into the left atrium of the heart. It is then pumped into the left ventricle. The heart then pumps the blood containing the red blood cells at very high pressure through the arteries around the body.elevance. Rating Newest Oldest. Best Answer: The right atrium collects deoxygenated blood cells in the blood from the body in the systemic circuit, and pumps it into the right ventricle where it passed into the pulmonary artery in the pulmonary circuit. The red blood cells then becomes oxygenated.
