Immunity in Spleen (animation)

The spleen is a critical organ in the immune system.
1. White Pulp
- The white pulp of the spleen is rich in lymphocytes (T cells and B cells) and is structured around central arteries.
- It functions similarly to lymph nodes, screening the blood for pathogens.
- When pathogens or antigens are detected, B cells can become activated and produce antibodies, while T cells can become activated to help in the immune response.
2. Red Pulp
- The red pulp is involved in filtering the blood, removing old or damaged red blood cells and platelets.
- It also serves as a reservoir for monocytes, which can differentiate into macrophages and dendritic cells to aid in the immune response.
3. Marginal Zone
- The marginal zone is a transitional area between the red and white pulp.
- It contains specialized B cells that can rapidly respond to blood-borne pathogens and produce antibodies.
4. Pathogen Clearance
- The spleen traps and destroys bacteria and other pathogens in the blood.
- Macrophages in the spleen engulf and digest these pathogens.
5. Immune Response Coordination
- The spleen helps to initiate and coordinate the body's immune response.
- It acts as a site for interaction between various immune cells, enhancing the body’s ability to fight infections.
Overall, the spleen is vital for both innate and adaptive immunity, playing a multifaceted role in detecting, responding to, and clearing pathogens from the bloodstream.
