Oxygen is carried in the blood in two forms: (1) dissolved in plasma and RBC water (about 2% of the total) and (2) reversibly bound to hemoglobin (about 98% of the total). At physiological PO2 (40 &#60; PO2 &#60; 100 mm Hg), only a small amount of oxygen is dissolved in plasma since oxygen has such a low solubility.
All arteries carry oxygenated blood with the exception of the pulmonary artery from the right side of the heart to the lungs, which does not. Yes.Most arterial blood is oxygenated. There are two exceptions to that rule. One is the pulmonary artery which carries deoxygenated blood. Veins do carry deoxygenated (oxygen-poor) blood into the heart.   Superior and inferior vena cava carry the oxygen-poor blood to the heart; blood enters into the righ â¦ t atrium.   Contraction of the atria forces the blood into the ventricles.
