2. Differentiate between polymorphonuclear and mononuclear cells. Polymorphonuclear cells are cell containing many nuclei. It that has granules (small particles) with enzymes that are released during infections, allergic reactions, and asthma. Neutrophils, eosinophils, and basophils are polymorphonuclear leukocytes. While, mononuclear cells are any cell that has a single round nucleus; for example, lymphocyte, monocyte. These cells are a critical component of the immune system to help fight infection.
3. Describe the functions of b and t lymphocytes.
B-lymphocytes are direct antigen recognition, differentiation into antibody-producing plasma cells and also involves in antigen presentation within class ii MHC. While t-lymphocytes involved in both humoral and cell mediated response, recognizes antigen presented within class ii MHC and promotes differentiation of b-cells and cytotoxic T-cells.
4. Give examples and functions of cells classified as ‘antigen presenting cells’. An antigen-presenting cell (APC) or accessory cell is a cell that...
