Lymphatic system
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.
The capillaries have direct contact with cells in the body. They are tiny blood vessels where the exchange of oxygen, nutrients, and waste products occurs between the blood and the surrounding tissue cells.
Red blood cells are taken out of circulation in the spleen. Their iron is recycled and stored in the liver.
Immature cell types released into the blood circulation are called "blast cells." These are undifferentiated cells that have the potential to develop into various types of mature blood cells, such as red blood cells, white blood cells, or platelets. The presence of blast cells in the blood may indicate abnormal cell development, as seen in conditions like leukemia.
A drop in hematocrit can occur due to factors such as dilution from increased fluid intake or intravenous fluids, which can increase plasma volume without a corresponding increase in red blood cells. Additionally, conditions like anemia or bone marrow dysfunction can impair red blood cell production, leading to a decrease in hematocrit levels. Other causes might include hemolysis, where red blood cells are destroyed faster than they can be produced, or shifts in body fluids that affect the concentration of red blood cells in circulation.

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?
Red blood cells are carried along passively by blood circulation, so if anything can be said to control them, it would be the heart. Their function of carrying oxygen to the cells of the body happens automatically, without any kind of regulatory mechanism other than changes to blood circulation.

The procedure you're referring to is called leukapheresis. In leukapheresis, white blood cells are separated from the blood, often for therapeutic purposes such as treating certain blood disorders or collecting stem cells for transplantation. The remaining components of the blood are then returned to the patient's circulation. This process helps to reduce the number of white blood cells or collect specific types for further treatment.
