Following are the two advantages of endoplasmic reticulum in the cell.
1) Endoplasmic reticulum is an organelle of the cell which is responsible for the production of protein for the cell. This protein is sent to the Golgi apparatus where it is modified and then used by cell where it is needed.
2) Endoplasmic reticulum also helps in removing of toxic substances from the cell. If these toxic substances can't be removed, it causes harm to the cell.
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.
