When fresh air is inhaled, oxygen is the primary substance that is added to the blood in the capillaries of the alveoli. As air enters the alveoli, oxygen diffuses across the alveolar membrane into the capillaries, where it binds to hemoglobin in red blood cells. This process is essential for delivering oxygen to tissues throughout the body, supporting cellular respiration and energy production. Additionally, carbon dioxide, a waste product, is released from the blood into the alveoli to be exhaled.

The alveoli are the sites of respiration: the oxygen in them provided by the inhaled air diffuses into the blood cells that flow through the capillaries. Carbon dioxide diffuses out of the blood and into the alveoli so it can be exhaled. The capillaries provide a way for the blood to reach the alveoli. Hope this helps
Alveolar capillaries do not inhale; rather, they facilitate the exchange of gases during respiration. When air is inhaled into the lungs, oxygen diffuses from the alveoli into the blood within the capillaries, while carbon dioxide moves from the blood into the alveoli to be exhaled. This process is crucial for supplying oxygen to the body and removing carbon dioxide, a waste product of metabolism.
answer the question ppl
Gas exchange between inhaled air and the blood occurs across the capillaries of the alveoli in the lungs. Oxygen from the inhaled air diffuses through the thin alveolar walls into the blood, where it binds to hemoglobin in red blood cells. Simultaneously, carbon dioxide, a waste product of metabolism, diffuses from the blood into the alveoli to be exhaled. This efficient exchange is driven by differences in partial pressures of the gases.

Oxygen enters the blood through the process of diffusion in the lungs. In the alveoli, oxygen from inhaled air diffuses into the blood in the surrounding capillaries, where it binds to hemoglobin in red blood cells for transport to tissues throughout the body.
The smallest blood vessels are the capillaries.
The thin walls of the blood vessels are capillaries around the alveolar sacs that permit diffusion of gases in every single red blood cell with oxygen inhaled ... they are thinner to improve the pressure gradient to allow more O2 in the capillaries, because the pulmonary capillaries have the lowest blood pressure in the body (normally)
Inhaled oxygen will diffuse through the walls of the lungs. It will also diffuse through the walls of red blood cells so it can be carried all over the body.
Capillaries contain oxygenated blood.
Blood does not move faster through the capillaries. Blood flow is slowest in the capillaries.
