Spleen

Spleen is the largest of the lymphoid organs. It has a capsule from which descent trabaculae dividing the organ into several intercon-nected compartments. Spleen is made up of white pulp and red pulp

 



 

White pulp

The spleenic artery travels along the trabaculae. On entering the spleen the artery divides into arterioles which are surrounded by lym-phoid tissues. This part is called white pulp. White pulp is rich in lym-phoid cells.

Red pulp

It is called red pulp because of the red blood cells. Macroph-ages also are present in this area


Functions of spleen

1.     The spleen serves as the grave yard for red blood cells

 

2.     The white pulp is rich in T cells and B cells

 

3.     The T cells are seen peripherally and the B cells are seen centrally

 

4.     After an antigenic stimulus the germinal center containing large num-ber of B cells and plasma cells appear in the periarteriolar areas and almost replace T cells.
