Because your living cells constantly produce Carbon Dioxide. So if your muscles are producing Carbon Dioxide constantly and then your blood cells come along carrying oxygen, the Carbon Dioxide is pulled into your blood vessels and exchanged with oxygen. So then when your blood cells come in contact with the lower pressured air in the alveolus, the opposite happens...carbon dioxide is pulled out of the blood cells and into the air while oxygen is pulled inward.

∙ 13y agoOxygen is carried in the blood by virtue of combining reversibly with the haemoglobin in the RBC to form oxyhaemoglobin, an unstable compound that forms when the oxygen binds to the heme component of the protein hemoglobin in red blood cells. It travels in this form until it reaches the recipient cells, in this case the muscle cells, and then is released, passes through the capillary wall, diffuses into the cell and then is utilized by the muscle cell.

∙ 14y agoWe need oxygen for aerobic respiration, which takes place all the time in our cells. In the alveoli of the lungs, oxygen diffuses into our capillaries mainly due to a steep concentration gradient, thanks to a rich blood supply which passes the alveoli. Diffusion is further aided by having a thin cell membrane for the gases to pass through - less than 40 micrometres! The same happens as the capillaries, rich with O2, pass by our cells. The gradient of oxygen between the blood plasma and the cytoplasm of our cells is such that the gas transfers into the cell. The capillaries are one cell thick, and permeable, to ensure this diffusion occurs as efficiently as possible.

∙ 13y agoThis process is thru the use of passive transport. The oxygen in you lungs are of a higher concentration than it is in your blood and since hemoglobin likes oxygen it moves naturally into the the blood supply in the lungs. Your blood is then returned to the heart and pumped throughout the body. Because your blood has more oxygen in it than your cells do the blood thru the use of passive transport again give the oxygen to the cells and pick up waste product and carbon dioxide to be returned eventually to the heart. Your blood is then returned to the lungs where the blood once again disposes of the carbon dioxide thru the use of passive transport and picks up oxygen.

∙ 14y agoBecause there is more oxygen in the blood than the muscle, oxygen moves from the capillaries to the muscles down the concentration gradient naturally.

What causes oxygen from the water to diffuse into the blood?
the lungs causes oxygen from the water to diffuse 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.
What are the air sacs in the lungs through which oxygen and carbon dioxide diffuse into the blood?
AVEVOLIS
What are Air sacs in the lungs through which oxygen and carbon dioxide diffuse into and out of the blood are?
The humorus
Air sacs in the lungs through which oxygen and carbon dioxide diffuse into and out of the blood are the?
alveoli
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
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.
Will O2 diffuse from air to blood or from blood to the alveolar air?
It will be absorbed from the air into your lungs. Then when it reachs the alveolus it will diffuse from the alveolus into the blood capillaries down an oxygen concentration through diffusion where it will combine with the heamoglobin in the Red Blood Cells.
Inhaled oxygen diffuses through the walls of what?
Inhaled oxygen diffuses through the walls of the alveoli in the lungs into the surrounding capillaries, where it binds to hemoglobin in red blood cells for transport to tissues in the body.
What organ does the oxygen-carbon Dioxide take place?
Oxygen is brought into the blood, and carbon dioxide released from the blood, at the alveoli of the lungs. Gases diffuse across the alveolar membrane to enter or leave the blood.
What is the exchange of gases between the lungs and the blood called?
The exchange of oxygen and carbon dioxide is called restoration. Organisms that function with the help of respiration are human beings, other mammals, birds, and reptiles. Anything that breathes in oxygen and breathes out carbon dioxide is completing respiration.
Do red blood cells carry oxygen to all of the cells in the human body?
No - not really anyhow. Oxygen is brought to the lungs by breathing in air. The lungs function as an exchange system which loads up the red blood cells with oxygen. So lungs give oxygen to red blood cells which then deliver the oxygen to all the parts of the body.
