They have on their surface MHC 2
Include T lymphocytes
Include B lymphocytes
They have on their surface only MHC 2 without MHC 1
Include dendritic cells of lymphatic nodules

Includes action of B lymphocytes
It could be because of existence of IgA within saliva or tears
Its response is very rapid (secound time)
Includes antigen-presenting cells
Is because of phagocytic activity of neutrophils
Lymph nodes
Are distributed along the course of the lymphatic vessels
Its stroma is formed by epithelial cells
T lymphocytes are situated in its paracortex (inner cortex)
Its stroma is formed by connective tissue
Germinal center is part of its outer cortex
Outer cortex contains PALS
Lymph nodes
Possess afferent and efferent lymphatic vessels
Contains lymphatic sinuses
During inflammation becomes larger
Has not got any blood vessels
Paracortex (inner cortex) contains PALS
Plasma cells are in medullary cords
Select correct for the lymphatic system
