Answer #1

Answer is true

Because the hemoglobin saturation of oxygen is directly proportional to the partial pressure of the oxygen.In lungs the partial pressure of the oxygen is very high than co2 and the Carbon dioxide leaves the hemoglobin and oxygen binds to ir.Through the pulmonary capillaries the oxygenated blood reaches left side of the heart.The partial pressure of oxygen is high than co2 in ghe the oxygenated blood.So its hemoglobin saturation also increases.

The Red blood cells carry oxygen from the lungs to the tissues of the body and carry carbon dioxide from the tissues of the body to the lungs. Each red blood cell contains millions of hemoglobin proteins that bind to oxygen and carbon dioxide allowing for transport. (isotonic blood), the morphology of red blood cells can be described as slightly ovoid, biconcave disks. When severe dehydration occurs, blood becomes hypertonic: water exits red blood cells and enters into the blood...
