\ (When blood flows through capillaries, the fluid part of blood, oozes into intercellular spaces through minute pores of the, , capillary wall. This fluid, formed in the intercellular space, is the, , tissue fluid) t dots not contain RBCs, large protein molecules, d plateléts) Exchange of materials takes place between the tissue, fluid and cells. Tissue fluid is, absorbed into the blood and, lymph capillaries(Lytmph is, the tissue fluid inside the, lymph capillaries. ) 3, , , , , , , , , , , , , , , , , , , , _ Armoury of the human body, , inches of size, purple in colour, about 200, t. Located above the abdomen on the left, of the stomach. The largest organ of the immune, mamed spleen. Though it performs various, functions, providing immunity is the main function., Spleen consists of 2 types of tissues. Red pulp tissues, filter and remove old and damaged RBCs present in, bl66d. The reusable components in it, like iron are, ' protected. White pulp cells store T cells and B cells, which are the main components of the immune system., The lymphocytes which identify and destroy, , ic bacteria and viruses that enter the body,, ' Pp in the spleen and lymph nodes.
