24 Μαρ 2022 · Blood low in oxygen flows through the lungs . The pulmonary artery and its branches deliver blood to the capillaries that surround the alveoli. This blood is rich in carbon dioxide and low in oxygen. Oxygen flows into your blood . Carbon dioxide moves from the blood into the air inside the alveoli.
18 Απρ 2023 · The oxygen in inhaled air passes across the thin lining of the air sacs and into the blood vessels. This is known as diffusion. The oxygen in the blood is then carried around the body in the bloodstream, reaching every cell. When oxygen passes into the bloodstream from the air sacs, carbon dioxide leaves the blood and passes into the air sacs.

Your bloodstream then carries this waste gas back to the lungs where it is removed from the bloodstream and then exhaled.
24 Αυγ 2016 · This chapter deals with the way the lungs work, how they interact with the blood flowing through them and with the way oxygen is used by the cells of the body. The flow of oxygen and carbon dioxide in and out of the body is assured by breathing.
24 Μαρ 2022 · Blood loaded up with oxygen-rich red blood cells travels to the left side of the heart through the pulmonary veins. The heart then pumps the oxygenated blood to the rest of the body, where it moves from your blood vessels to your cells.
17 Μαΐ 2016 · Oxygen uptake into the blood. Deoxygenated venous blood becomes oxygenated in the pulmonary capillaries after diffusion down a concentration gradient across the alveolar capillary membrane (see Section 2: diffusive oxygen transport).
29 Ιουλ 2020 · The respiratory system allows air to reach the lungs, from which oxygen enters the blood and circulates to all body cells. This system also removes waste gases from the body and helps prevent...
