Answer:
This is the answer of your question. ☺☺
Explanation:
Biology is the study of living organisms, divided into many specialized fields that cover their morphology, physiology, anatomy, behaviour, origin, and distribution.
Macrophages engulf foreign material and destroy them using lysozymes.
When presented with antigen by antigen presenting cells, Helper –T cells produce
cytokines that activate B cells and triggers the adaptive immune response. T-helper cells determine the specificity of the adaptive response to an antigen. Cytotoxic-T-cells
destroys infected cells that have displayed an antigen on the MHC I surface receptors.
Suppressor T cells enable negative feedback by downregulating
immunity in cases when a foreign antigen
is eliminated. It also prevents autoimmunity.
Plasma cells are repsosncible for the production of antibodies in the humoral
immune response. Memory B and T cells ensure the immunity can remember an
infectious agent and therefore can launch a faster response in case of re-infection.
