WebbAlthough gas exchange is a continuous process, the oxygen and carbon dioxide are transported by different mechanisms. Transport of Oxygen in the Blood. Although oxygen dissolves in blood, only a small amount of oxygen is transported this way. Only 1.5 percent of oxygen in the blood is dissolved directly into the blood itself. WebbBlood travels through the arterioles and moves into the capillaries where gas exchange can occur. [citation needed] Capillaries are organised into capillary beds in tissues; it is here that blood exchanges oxygen for carbon dioxide waste. In the capillary beds, blood flow is slowed to allow maximum diffusion of oxygen into

WebbIn your lungs, your pulmonary arteries divide into many smaller blood vessels. Eventually, these smaller vessels lead to capillaries that surround alveoli (air sacs). This is where gas exchange takes place. Lungs: In your lungs, your blood refills its oxygen supply and gets rid of carbon dioxide. inby supply coupon code
