Oxygen - Hemoglobin Dissociation Curve

摘要

The delivery system of oxygen in the human body consist of lungs and CVS, which it depends by it self on the: 1 Amount of O2 entering the lung. 2 Adequacy of pulmonary gas exchange. 3 Blood flow to the tissue: witch depends on the degree of the constriction of the vascular bed in the tissue, and on the cardiac output. 4 Capacity of blood to carry O2: which depends on the amount of dissolved O2, amount of Hb in the blood, and affinity of Hb for O2
