spleen
Systemic circulation is also regarded as a greater circulation because it sends oxygenated blood to the cells of the body and takes de-oxygenated blood from the cells to the heart, Therefore the cells will live longer.
there are both single and double circulatory systems.fish have single ones, and birds have double.in double circulatory system the blood travels trough the heart twice in it's way around the body, while in the single it only goes through the heart once.Answer by FutureLPGAgolferThe answer came from my homework and I got it right, it's the Open system and the Closed system.explain how number of exercises affects the breathing rate?
A red blood cell lives about 120 days. Each day the normal adult produces almost 200 billion new red blood cells to replace the 200 billion that are removed from the circulation due to old age.
Blood cells are made in the bone marrow or stem cells of your body. The stem cells become red blood cells, white blood cells and platelets. Red blood cells are replaced every 120 days, platelets every 6-7 days and white blood cells everyday.
Perfusion
Red blood cells live about 120 days. When they get old their membrane started to show wear and they get removed from the blood circulation.
Human red blood cells circulate in the blood for approximately 120 days before they wear out and are removed from circulation.
Systemic circulation is also regarded as a greater circulation because it sends oxygenated blood to the cells of the body and takes de-oxygenated blood from the cells to the heart, Therefore the cells will live longer.
Blood is the fluid within the cardiovascular system, consisting of red blood cells, white blood cells and plasma. Blood circulation is the system through which the blood moves.

they are removed by your liver
The replacement of red blood cells primarily depends on the rate of production in the bone marrow and the lifespan of the cells. Red blood cells normally have a lifespan of about 120 days, after which they are removed from circulation and replaced with new ones. The body closely regulates the production of red blood cells to maintain a stable level of oxygen-carrying capacity in the blood.
Red blood cells are taken out of circulation in the spleen. Their iron is recycled and stored in the liver.
red blood cells
The spleen removes old red blood cells. It breaks down the erythrocytes and recycles the hemoglobin, sending the heme portion to the liver for storage and recycling. The spleen also filters bacteria from the blood.
