Which organ acts as a reservoir for red blood cells?

• A. Pancreas
• B. Liver
• C. Spleen
• D. Gallbladder

Answer: (C)

The spleen functions as a reservoir for red blood cells and plays a crucial role in the body’s circulatory and immune systems. It stores healthy red blood cells and can release them into the bloodstream when needed, particularly in situations such as blood loss or increased demand for oxygen. The spleen is also responsible for filtering blood by removing old or damaged red blood cells, thus maintaining the overall health of the blood cell population. The pancreas primarily produces digestive enzymes and hormones, such as insulin, and does not serve as a storage site for blood cells. The liver, while it has many metabolic functions and can store blood, is better known for filtering toxins and producing bile rather than acting specifically as a reservoir for red blood cells. The gallbladder's primary function is to store bile produced by the liver, aiding in digestion, and it does not have a role in blood cell storage. This makes the spleen the correct answer as it has a dedicated function in managing red blood cell reserves.
