    could you give me best answer please :)

    1. natural killer cell

    2Monoclonal antibodies (mAb or moAb) are monospecific antibodies that are the same because they are made by identical immune cells that are all clones of a unique parent cell. Monoclonal antibodies are typically made by fusing myeloma cells with the spleen cells from a mouse that has been immunized with the desired antigen.They are used in cancer treatment and autoimmune diseases.

    4. T regulatory cells are a component of the immune system that suppress immune responses of other cells. This is an important "self-check" built into the immune system to prevent excessive reactions. These cells are involved in shutting down immune responses after they have successfully eliminated invading organisms, and also in preventing autoimmunity.

    5.Arteries are VERY muscular. Veins & lymphatic vessels have very little muscle. Because of this, veins and lymph vessels must rely on the movement of the body's muscles to get the fluid in them (blood, lymph) to return to the heart. Veins and lymph vessels have valves to prevent backflow so that gravity isn't really a factor.

    The lymphatic system picks up lymph from all over the body and returns it back to the heart to prevent edema (swelling). For example. If you have cancer in your foot, the lymph vessels in your foot will pick up the lymph containing the cancer and carry it up your leg, through your abdomen and thorax into your heart. Through all this, the cancerous cells may leave and get "stuck" along the way in turn "spreading" the cancer from your foot to, say, your stomach.

    6.Complement.
