Gas exchange in the lungs occurs between blood in capillaries and air in?
alveolus
What small structure in the lung is the site of oxygen exchange with blood capillaries?
The alveolus or alveoli (plural).
What are tiny air spaces in the lungs by blood capillaries?
Alveoli. Singular is alveolus.
How do capillaries exchange substances between the blood and the tissues?
Oxygen and Carbon Dioxide.
Does the exchange of substances happen next to the blood capillaries?
this is a false statement blood capillaries do not exchange in diffrent part of your body
Where does the air terminate in the respiratory system?
Probably in the tiny "balloons" called alveoli (singular, alveolus). Each has its walls filled with capillaries that bring in blood rich in carbon dioxide/low in oxygen. The carbon dioxide diffuses into the alveoli (then exhaled) while the oxygen just inhaled diffuses from each alveolus into the capillaries and is carried throughout the body. The heart pumps the blood constantly and permits this exchange in the lungs.
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.
What Are sites of exchange between blood and tissue?
The exchange that takes place between organs and blood are **** and ********
What blood vessels permit the exchange of nutrients and gases between blood and tissue?
Capillaries
Because there is more oxygen in an alveolus than in the blood around it oxygen diffuses?
When there is more oxygen in an alveolus than in the blood around it oxygen diffuses from the capillaries to the veins. This is due to the high concentration of oxygen in the alveoli.
Exchange of nutrients and gases between the blood and tissue cells?
capillaries is where the exchange of materials occur such as; gases,nutrients, hormones, and so on.between the blood and the interstitial fluid.
What blood vessels do the exchange of gases occur?
the blood vessel which allows gas exchange to occur is the capillaries
