Air enters through the nose or mouth, this air then travels down the wind pipe, past the voice box and to the lungs. The lungs divide into two small tubes called bronchi, these bronchi then split into thousands of tiny tubes called bronchioles, at the end of these tiny bronchioles are millions of small 'air sacs' called alveoli. Once in the alvoli gas exchange of carbon dioxide and oxygen in the capillary walls happens.
The oxygen which you have breathed in through your nose or mouth is diffused through the capillary walls to meet red blood cells, which then take the oxygen to the heart, where it pumps the blood cells to cells all over the body that need oxygen to function and do its job correctly.
when this oxygen reaches the cells it kind of 'swaps' positions with the carbon dioxide (CO2) which has been created as a waste product by the body's cells.
Once the CO2 is attached to the blood cells, it is returned to the heart where it pumps the blood cells back to the lungs, where gas is diffused again and the cycle starts again.
sorry, a bit confusing.
carbon dioxide.
carbon dioxide.
Your lungs.
No. Your lungs pass oxygen into the blood and also pass carbon dioxide to the air outside your body. Oxygen combines with carbon to form carbon dioxide. This happens in our muscles, among other places.
The blood carries the carbon dioxide from the body cells to the lungs so the lungs can release the carbon dioxide when you exhale
There are two main gasses that are exchanged in the lungs: carbon dioxide and oxygen. The lungs use tiny air chambers called alveoli to take in oxygen and let out carbon dioxide.
The heart pumps the blood that takes carbon dioxide to the lungs. So, the heart is a necessary element, but isn't the one effectively doing it.
Breathing is the movement of air into and out of the lungs. Respiration is the exchange of oxygen and carbon dioxide. Oxygen is picked by and carried to the cardiovascular system and taken to the cells. The cells take up the oxygen and release the carbon dioxide back into the CVS and out to the lungs. The lungs take in oxygen and release carbon dioxide.
Air contains oxygen, carbon dioxide, nitrogen, and other compounds. We take carbon dioxide into our lungs all the time, but our lungs keep the oxygen. However, if you were in a room with ONLY carbon dioxide, you would die--not from carbon dioxide per se, but from lack of oxygen.
the main function of our lungs in to take away carbon dioxide and refill the blood with oxygen
The gas exchange that takes place in the lungs are carbon dioxide and oxygen.
The lungs take in oxygenated air and gets it to the blood. It then releases the carbon dioxide out of your body.
