What else can I help you with?
What type gas moves from the alveoli into the blood?
o2
What are the two gases that diffuese the alveoli and the capillaries?
CO2 and O2
Where in the human body is o2 and co2 exchanged?
Oxygen (O2) is exchanged for carbon dioxide (CO2) in the lungs. In the alveoli, tiny air sacs in the lungs, oxygen from the air is transferred into the bloodstream while carbon dioxide from the blood is released into the air to be exhaled.
Where are alveoli located in human body?
Alveoli are very tiny air sacs found in the lungs where CO2 and O2 are changed.
What is relationship of the alveoli to capillaries?
The alveoli branch from the bronchioles and are responsible for gas exchange with the pulmonary capillaries. They come in close contanct with the capillaries so the exchange of O2 and Co2 can occur rapidly and easily.
What is the Diffusion of gases between alveoli and blood?
The Diffusion is the exchange of oxygen (O2) and carbon dioxide (CO2) between the alveoli and the blood. So blood that is pumping through the capillaries in the lungs has a low concentration of O2 and a high concentration of CO2, in the alveoli it is high concentration O2 low concentration CO2. Therefore the 2 gases exchange across the alveoli membrane by diffusion trying to establish a concentration gradient.
Why partial pressure of O2 falls from trachea to alveoli?
There is more space that is occupied by H20 in the alveoli than the trachea. (BTPS - body tempertaure ,pressure saturated)
How are breathing and circulation linked?
They are linked in the alveoli of the lungs where CO2 escapes from and O2 is captured by the blood.
Is o2 concentration greater in the pulmonary capillaries or alveoli?
In the alveoli
Which way would O2 and CO2 diffuse during internal respiration?
O2 would diffuse into the cells, and CO2 would diffuse into the systemic capillaries.
How the movement of oxygen takes place in human?
During Inhalation the Oxygen enters the Alveoli of the lungs . The alveoli is surrounded by very tiny Blood vessels called Capillaries . Through Diffusion The O2 Moves out of the alveoli and into the Blood . Now the Blood carries it all over to the body with the help of Hemoglobin .The Blood Passes through Tissues then the O2 diffuses into the cells due to its higher concentration in the blood .The O2 Combines with the digested food present in the cells to give out Energy . So this is how O2 moves . Hope This Helped Thanks
Where in your respiratory system does the exchange of O2 happen?
Gaseous exchange occurs in the alveoli (singular = alveolus) of the lungs.
