The immune system monitor continuously the lymphocyte cell levels in order to ensure the protection of the body. These cells are a type of white blood cells that are important in determining the specificity of the response of the body to foreign substances and infectious microorganisms. This group of cells include the T cells, B cells and the natural killer cells. These are produced in the bone marrow and are transported to the lymphatic systems like the thymus, spleen and the lymph nodes. The NK cells function in cytotoxic innate immunity or the cell-mediated ones. T-cells would function by connecting to virus antigens on the outside of a cell that is infected while B-cells would connect to the virus directly in its surface.
Answer:
THYROID GLAND
Explanation:
Thyroid gland functions in metabolisms by activities of thyroid cells.This cells withdraws Iodine from metabolites and combine it with amino acid tyrosine for productions of Thyroid hormones:
ThyroxineT3,(20%)
TriiodothyronineT4(80%). This production is under the influence of Thyroid stimulating hormones,regulated by the pituitary gland,
T3 and T4 increase calorinogenesis, (liberation of heat from digestion to supply energy,and oxygen consumption of the heart.)
Deficiency of thyroid hormones are goiters, hypothyroidism, and hyperthyroidism
