The heart is the organ that keeps the blood flowing. Valves in the heart ensure the flow is only in one direction.
No organ holds blood. Blood is constantly flowing through the circulatory system. It never stops (unless you are dead)
It may prevent blood from flowing throughout the affected organ - reducing efficiency, or stopping it from working.

True
your heart is the organ in your body that keeps you living and pumps your blood all through you veins
Pituitary gland
The volume in the organ is determined by the amount of blood flowing through it, which is regulated by factors like blood pressure, heart rate, and the elasticity of blood vessels. The organ itself can also adjust its size and blood flow based on metabolic demands and signals from the nervous system.
The Heart.
Blood vessel diameter is the most effective and easiest factor to control from moment to moment for regulating blood flow to a particular organ. By constricting or dilating the blood vessels, the body can quickly adjust the amount of blood flowing to an organ based on its needs.
The pump that keeps your blood circulating through your body is called the heart. It is a muscular organ that pumps blood throughout the circulatory system, providing the body with essential nutrients and oxygen.
Blood is not an example of organism because it does not exhibit all the characteristics of life. However, it is a vital component in most organisms.
Your kidneys filer your blood of nitrogenous wastes. These wastes are then moved to the bladder in the form of urine and expelled.
