Oxygen Saturation At Various Points Through Circulation Complete each statement describing the degree of O2 saturation of the blood as it circulates through the lungs and the body. Then place each sentence in the order of blood flow, starting with blood at the alveoli. Assume normal, non-diseased, sea-level conditions out of 75% 100% 46 mmHg Into 0% systernic 40 mmHg pulmonary 25% Drag the text blocks below into thelr correct order. Blood arriving in the capillanes is exposed to an alveolar PO, of 104 mmHg, higher than that of the blood The pressure gradient causes oxygen to diffuse the blood Aner passing through the systemic capillaries, blood is about saturated with oxygen. The blood is now said to be "oxygen-poor" Returning to the inferior vena cava, the right side of the heart, and the pulmonary arteries, the PO in the blood is it will once again return to the lungs to be oxygenated As red blood cells pass through the capillaries, oxygen is unloaded and carbon dioxide is picked up o Blood in the pulmonary veins is close to saturated with oxygen
