Final answer:
Red pulp in the spleen is rich in macrophages and red blood cells, serving as a filtration system for the blood and immune response.
Step-by-step explanation:
The red pulp of the spleen is rich in macrophages and red blood cells. Red pulp in the spleen is rich in macrophages and red blood cells, serving as a filtration system for the blood and immune response. Macrophages are specialized cells that engulf and destroy old and damaged erythrocytes, as well as other foreign materials in the blood.
This function is part of the body's defense system, removing unwanted substances from circulation and recycling important components, like iron from hemoglobin.
In addition to this, the red pulp also serves as a storage for new red blood cells, ensuring a steady supply for the body's needs. The white pulp, on the other hand, is rich in lymphocytes and functions in the adaptive immune response, playing a critical role in identifying and fighting infections.
