Air exchange
What else can I help you with?
What is a specific molecule that diffuses into the blood at the lungs?
oxygen
Oxygen diffuses into the capillaries of the lungs because there is?
It diffuses because the concentration of oxygen in the capillaries is lower than the concentration of oxygen in the air (law of diffusion).
When you exhale but dn't delibirately inhale why does air still flow into your lungs?
Because air diffuses from high pressure to low pressure, when we breath we aren't really "sucking" air in, our diaphragm lowers and our ribcage extends allowing our lungs to "expand" air then diffuses from the outside of the body into our lungs, when the diaphragm contracts it creates a higher pressure in the lungs compared to the outside, so air then diffuses from the lungs and out of the body.
In haled oxygen diffuses through the walls of the?
Alveoli in the lungs.
Which organ in your body diffuses oxygen into your blood stream?
your lungs
What does oxygen diffuse into?
Oxygen diffuses from any place there is a lot of it to any place where there is less. In the body, it diffuses from the air in the alveoli of the lungs, through the lung and capillary walls and into the blood, where it is taken up by the haemoglobin of the red blood cells. When the bood reaches the body tissues it diffuses out of the blood and into the cells.
Oxygen diffuses into the capillaries of the lungs because there is a?
greater concentration of oxygen in the air sacs of the lungs than in the capillaries.
What gases are exchanged in the repitory ystem?
Oxygen diffuses from the alveoli of the lungs into the blood. Carbon dioxide diffuses from the blood into the alveoli of the lung where is will be exhaled.
Which gas diffuses the oxygen?
In the lungs, oxygen diffuses from the alveoli into the bloodstream through the process of gas exchange facilitated by differences in partial pressure.
What brings air into contact with blood?
In the human body, air is brought into contact with blood in the lungs. This happens through the process of respiration, where oxygen from the air diffuses into the blood in the capillaries surrounding the alveoli in the lungs, and carbon dioxide from the blood diffuses into the air to be exhaled.
Where oxygen diffuses into red blood cells and carbon dioxide diffuses out?
This process occurs in the capillaries of the lungs. Here, oxygen from inhaled air diffuses into red blood cells in exchange for carbon dioxide, which then diffuses out of the red blood cells and is exhaled from the body.
What is the process of exchanging gases with the bloodstream called?
The process of exchanging gases with the bloodstream is called respiration. In the lungs, oxygen from the air we breathe diffuses into the bloodstream while carbon dioxide from the bloodstream diffuses into the air in our lungs to be exhaled.
