How do mammals breathe?
Mammals breathe using organs called lungs. They take air in and the oxygen is exchanged for carbon dioxide in small organelles called alveoli. This carbon dioxide is then expelled.
What do the alveoli in the body do?
alveoli take co2 from
Where does exchange of oxygen and carbon dioxide take place?
The exchange of oxygen and carbon dioxide takes place in the alveoli of the lungs. Oxygen from the air we breathe diffuses into the bloodstream, while carbon dioxide from the bloodstream diffuses into the alveoli to be exhaled out of the body.
What route would you take starting at Chang'an ending at Kashgar?
bamiyan, afghanistan
How does your body remove CO2and take O2?
Your body removes CO2 by exhaling it out of your lungs when you breathe. It takes in O2 through your lungs when you breathe in. The exchange of gases occurs in the alveoli, tiny air sacs in the lungs where oxygen is absorbed into the bloodstream and carbon dioxide is released.
What path does the air take when we breathe in?
When we breathe in, air enters through our nose or mouth, travels down the throat (pharynx), passes through the voice box (larynx), then enters the windpipe (trachea). The trachea branches into two bronchi, which further divides into smaller bronchioles that lead to the lungs where oxygen is exchanged with carbon dioxide in the alveoli.
How our lungs work?
When we breathe in, air enters our lungs through the trachea (windpipe) and moves into smaller airways called bronchi, bronchioles, and finally, into tiny air sacs called alveoli. In the alveoli, oxygen from the air passes into capillaries to enter the bloodstream, while carbon dioxide moves from the blood into the alveoli to be exhaled when we breathe out. This gas exchange process allows oxygen to be delivered to cells throughout the body and removes carbon dioxide waste.
What gas do alveoli take from the blood?
oxygen
When you breathe in what do you take in?
When you inhale (take in air when you breathe), you are taking in Oxygen.
How does the blood get oxygen?
by suking it
How gaseous exchange take place in the alveoli?
We have followed the path of the air and of the oxygen into the bloodstream. But breathing is a two-way street: we breathe in and then we breathe out. When we breathe in, or inhale, oxygen is removed from the air. Breathing also removes waste from the lungs and from our noses and mouths. How does this waste material get into the air that we breathe out, or exhale? The thin walls of the alveoli actually have two purposes. When we breathe in, oxygen passes through the walls of the alveoli and into the blood. Carbon dioxide and water vapor then travel the opposite direction. They are the main waste products that pass from the blood vessels (arteries) in the lungs, into the alveoli, through the windpipe and out the nose and mouth.
Where does the difussion of gases take plce in the body?
Alveoli.
