Detailed explanation-1: -The role of blood plasma is to carry oxygen to the needy tissues. The role of tissue fluid is to transport nutrients from the blood to the cells also, the exchange of gas takes place. Tissue Fluid when entering a lymphatic capillary is known as lymph.
Detailed explanation-2: -Fluid found in the spaces around cells. It comes from substances that leak out of blood capillaries (the smallest type of blood vessel). It helps bring oxygen and nutrients to cells and to remove waste products from them.
Detailed explanation-3: -High hydrostatic (liquid) pressure exists at the arterial end of the capillary. The hydrostatic pressure inside the capillary is higher than the hydrostatic pressure in the tissue fluid. This difference in pressure forces water and other small molecules out of the capillary, forming tissue fluid.
