Rhombus - Area. 1  As for all parallelograms, the area K of a rhombus is the product of its base and its height (h). 2  The area can also be expressed as the base squared times the sine of any angle... 3  or in terms of the height and a vertex angle... 4  or as half the product of the diagonals p, q...
Helper T cells augment the immune response by recognizing the presence of a foreign antigen and then stimulating antibody production and producing cytokines that âturn onâ or activate other T cells. Regulatory T cells function in an opposite manner: they dampen or turn off the immune response.
The white blood cells involved in the acquired immune response are called lymphocytes. There are two main types of lymphocytes â B cells and T cells. B and T lymphocytes are made in the bone marrow, like the other blood cells. Lymphocytes have to fully mature before they can help in the immune response.B cells mature in the bone marrow. But the immature T cells travel through the bloodstream to the thymus gland where they become fully developed.ntibodies can also detect and kill damaged cells. The B cells are part of the memory of the immune system. The next time the same germ tries to invade, the B cells that make the right antibody are ready for it. They are able to make their antibody very quickly.
