Question: Describe the path taken by a red blood cell as it passes from the left atrium to the cells in the cell kidneys and back to the left atrium

Answer: The red blood cells enter through the right atrium and there the blood color is blue. Next, it goes through the right ventricles, and then to the pulmonary artery. After goes through those valves, it then goes through the lungs, and the lungs turn the blood into red, thus stating that it contains oxygen. Pass the lungs, and then into the pulmonary vein, and the left atrium and onto the left ventricle. From the left ventricle, it goes though the aorta and arteries, and then into the arterioles. After passing through the arterioles, it goes into the capillaries, where the blood color is changed from red to blue, which now the blood contains no oxygen. After the blood color has been changed, it goes through the venules, then to the veins, and then the to the vena cava. After going through the vena cava, the cycle is repeated, so the blood is returned back to the right atrium. This is the path taken by a red blood cells.
