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 pulmonary veins carry oxygenated red blood cells from the lungs to the heart. They also carry wastes in the form of carbon dioxide back to the heart from the body tissues. red blood cell red blood cells, or erythrocytes the job of the red blood cells is to carry oxygen to all your cells Hemoglobin-blood cells.ed blood cells carry oxygen by binding oxygen molecules to hemoglobin (an iron based molecule).   Yes. White blood cells fight infections and â¦ other germs, and palates clot cuts. You need to intake a certain amount of iron to collect the oxygen on your red blood cells.
