Name and describe the six main types of lymphatic cells, discuss their contribution to immunity ( 250 words)

Solution

Lymph is the extarvassation or Diapedisised (Filtrate from Blood vessels to inter tissue space) material and it contain all types of white blood cells and excecute immunity to the Body

It contain several types of Cells:

Those are

B-Cells: B-Cells originate and developed in Bone marro and involved in Humoral mediated immunity. Some B-Cells also act as Antigen presenting cells

T-Cells: T-cells originates in Bone marrow and developed in Thymus and involved in Cell mediated and Humoral mediated immunity

Macrophages: These are tissue specific monocytes and principal Antigen presenting cells. They engulf the antigen and process it and finally submit to MHC molecules. These MHC molecules present the antigen fragments on the surface of Macrophages. Then they are recognised by T-helper cells and finally excecute cell mediated or Humoral medited immunity for elimination of Antigen

Dendritic Cells: These are a type of Antigen presenting cells and originated from both Lymphoid and Myloid lineage and play important role in Cell mediated and Humoral mediated immunity

Neutrophills: They are multilobed nuclei containing cells and they first recognises the pathogen entry in to the host. After recognition, they convay the information to Macrophages

Basophills: They contain Basic nature granules and later on converted in to mast cellls. In association with IgE antibody, these cells involved in Hypersensitivity type I reactions and causes allergy

Eiosinophylls:They are also called Acidophylls due to the presence of Acidophilic granules in its cytoplasm and they protects from Helmenths infection.
