What are the cells involved innate immune system ?

Explanation

Lymphocytes:About 20-30 % of the white blood cells are lymphocytes.They hace a large nucleus filling most of the cell, surrounded by a little cytoplasm.The two main types of lymphocytes (B cells)stay in the blood,While others accumulate in the lymph nodes and spleen.T lymphocyes leave the bone marrow and mature in the thymus gland.Once mature,T cells also accumulate in the same areas of the body as B cells .Lymphocytes have receptor protiens on their surface.When receptors on a B cell bind with an antigen,the cell becomes activated and divides rapidly to produce plasma cells.THe plasma cells produce antibodies.Some B cells do not produce antibodies but become memory cells.These cell are responsible for secondary immune response.T lymphocytes do not produce antibodies.They reconsible for secondary immune respone.T lymphocytes do not produce antibodies.They recognize antigen-presenting cells and destroy them .The two important types of T cells are Helper T cells .Killer more around the body and destroy cells which are damaged or infected.Apart from these more around the body and destroy foreign cells by phagocytosis.Monocytes when they mature into large cells ,THey are called macrophages which performs phaocyrosis on any foreign organism.
Dendritic cells are called so because its covered with long ,thin membrane extensions that resemble dendrites of nerve cell.These cells present the antigen to T-helper cells.Four types of dendritic cells are known.They are langerhans,interestitial cells,myeliod and lymphoid cells.
