GENERAL HISTOLOGY

Detailed explanation-1: -The spleen, which is 4 inches long and sits in the upper abdomen, acts as a reservoir of immune cells that speed to the site of heart injury after a heart attack to begin clearance of damaged tissue. Those leukocytes can lead to either heart protection or pathology, depending on how the immune response progresses.

Detailed explanation-2: -The spleen acts as a filter for your blood The spleen recognises old, or damaged red blood cells and removes them from your body by breaking them down and saving any useful components, such as iron, in the process. This keeps the blood circulating in your body clean and functioning at its best.
