THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Oxygen diffuses through the capillary wall, into the tissue fluid and the cells. Carbon dioxide diffuses from the cells into the tissue fluid, then across the capillary walls into the blood plasma . Glucose diffuses from the blood plasma, across the capillary walls to the tissue fluid, and then to the cells.

Detailed explanation-2: -Its composition is water, amino acids, fatty acids, salts, sugars, hormones, coenzymes, white blood cells and metabolic waste products. All the nutrients and minerals are pushed out from the capillaries into the tissue fluid, and later taken up by the cells in the tissues.
