There are two cells that oxygen must diffuse from. Once the oxygen enters the lungs, it is pushed to the aveoli, which is one cell thick and where the gas exchange occurs. Surrounding it are capillaries, which is also one cell thick. Here, oxygen moves across the two cells while the CO2 exits the red blood cell to exit the lungs.

The oxygen diffuses into the blood stream from the alveoli in the lungs. There are millions of these tiny sacs, which enables a greater volume of gases to exchange across the membranes, as a result of the increased surface area.

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.


What are the air sacs in the lungs through which oxygen and carbon dioxide diffuse into the blood?

AVEVOLIS

Inhaled oxygen diffuses through the walls of what?

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.


Where in the lungs does oxygen and carbon dioxide diffuse across in the lungs?

since the air in lungs have more oxygen than the blood in the surrounding, the oxygen will be difused to the blood, similerly the quantity of carbon dioxide in the surrounding blood will be more compared to that in the lungs. so again difussion takes place, thus happens the exchange. no osmosis(the exchange of water from a place with a high concentration of water to a place with low concentration of water) but there is diffusion.


Because they trap oxygen from the atmosphere in the water for animals to breathe?

The lungs are the organs that "trap" oxygen from the atmosphere for animals to breath. Lungs do not really trap oxygen, however, they present a tissue to the oxygen-rich air in which the oxygen may diffuse into, where it can be captured by the hemoglobin in the blood.


Are lungs moist or dry?

For oxygen to diffuse into capillary beds of any organism, there needs to be a certain amount of moisture.


What happens when the breathing rate increases in humans?

A) additional oxygen will diffuse into the blood as carbon dioxide diffuses out of the blood in the lungs


What determines in which direction carbon dioxide and oxygen will diffuse in the lungs?

pressure difference between carbon dioxide and oxygen level between pulmonary artery and alveolar space


Where does the transfer of oxygen into the bloodstream take place?

normally the oxygen transfer from the lungs to the cells through haemoglobin in most of the animals. the oxygen transfer occurs in lungs from the atmospheric air.
