What Happens When Blood Reaches the Lungs? Blood that reaches the lungs travels throughout a community of small blood vessels, the place oxygen strikes into the blood and carbon dioxide strikes out of the blood, based on the National Heart, Lung and Blood Institute. This oxygen-wealthy blood is transported by way of the pulmonary veins and again to the heart, the place it's pumped out to the remainder of the physique. The air trade in the lungs is necessary to the body’s total functioning. Oxygen that enters the blood within the lungs is obtained via air that is breathed in, or inhaled. The National Heart, Lung and Blood Institute explains that inhaled air travels down the windpipe, by way of the bronchial tubes and into small air sacs known as alveoli. Small blood vessels referred to as capillaries encompass the alveoli. Oxygen passes by means of the thin partitions of the alveoli and into the blood within the capillaries. A protein in the crimson blood cells called hemoglobin helps to transport the oxygen. At the same time, carbon dioxide passes from the blood into the alveoli. When air is breathed out, or exhaled, the air contained within the alveoli, which is wealthy in carbon dioxide, is pressured out of the lungs and exits the physique by the nose and mouth.
