Oxygen diffuses rapidly into the blood due to the concentration gradient between the alveoli in the lungs and the blood in the capillaries surrounding them. The alveoli have a high concentration of oxygen, while the blood has a lower concentration, which drives the diffusion of oxygen across the thin walls of the alveoli and capillaries. Additionally, the large surface area and short diffusion distance in the lungs help facilitate the rapid diffusion of oxygen into the blood.

Why does oxygen diffuse into the blood instead of the active transport?
Oxygen is a small molecule that can easily diffuse across cell membranes, including the membranes of red blood cells. This passive diffusion process is faster and more efficient than active transport for molecules like oxygen that are able to freely move across cell membranes.
By what process does oxygen diffuse from air into blood?
Oxygen diffuses from air into blood through the process of simple diffusion. This occurs in the lungs where oxygen moves from areas of high concentration in the alveoli to areas of lower concentration in the blood capillaries. The concentration gradient allows oxygen to pass through the alveolar walls and enter the blood.
Where in the body does oxygen diffuse into the blood from air?
Oxygen diffuses into the blood from the air in the lungs. This occurs in the alveoli, which are small air sacs in the lungs where gas exchange takes place. Oxygen crosses the thin alveolar membrane and enters the bloodstream to be carried to the body's tissues.
How do cells inside lacunae receive oxygen?
Cells inside lacunae receive oxygen through diffusion from nearby blood vessels. Blood vessels supply oxygen to surrounding tissues, which then diffuse into the lacunae where the cells reside. This process ensures that the cells inside lacunae receive the necessary oxygen for their metabolism.
What does inhaled oxygen diffuse through through?
Inhaled oxygen diffuses through the walls of the alveoli in the lungs, then into the bloodstream where it binds to hemoglobin in red blood cells for transportation to tissues and cells in the body.
What causes oxygen from the water to diffuse into the blood?
the lungs causes oxygen from the water to diffuse into the blood
What gas diffuse from the tissues to the blood?
Both oxygen and carbon dioxide diffuse from body tissues into the blood.
Oxygen diffuse into the blood at the alveoli?
Carbon dioxide does.
What gas diffuses from the tissues to the blood?
Both oxygen and carbon dioxide diffuse from body tissues into the blood.
What is the exchange of gases between the blood and air?
Diffusion. In the lungs, oxygen will diffuse into de-oxygenated blood (oxygen was removed from the blood in the body) and carbon dioxide will diffuse out of the blood into the lungs and expelled from your body when you breathe out.
Does oxygen diffuse from large blood vessels into the bodies cells?
YES
Where does oxygen diffuse into the blood during the process of respiration?
Oxygen diffuses into the blood from the air sacs in the lungs during the process of respiration.
What are four different substances that can diffuse in and out of your blood?
Oxygen, carbon dioxide, carbon monoxide, and glucose are just four substances that can diffuse into and out of your blood. There are many more.
How does the fetus obtain food and oxygen?
The mother's blood supply enters the foetus via the umbillical cord and allows oxygen to diffuse from the mother's blood into the foetus.
What causes oxygen to diffuse into the blood from the alveoli - simplest anwer?
A diffusion gradient.
How does long term exercise affect oxygen diffusion rates?
An increase in diffusion rates in tissues favours oxygen movement from the capillaries to the tissues, and carbon dioxide from the cells to the blood. Also With some training these rates increase, allowing oxygen and carbon dioxide to diffuse more rapidly.
Nutrients and oxygen diffuse into body cells from what?
Blood -> plasma -> extracellular fluid -> cells.
