The gaseous exchange of oxygen (O2) and carbon dioxide (CO2) occurs within the lungs. Oxygen is inhaled through the mouth and nose, it passes through the bronchi, which branch off into smaller airways called bronchioles. It is at the ends of these bronchioles where the Alveoli are, (tiny, pear shaped sacks).
When oxygen enters the Alveoli, it is diffused into the surrounding capillaries (which are one cell thick). It is also in the alveoli where carbon dioxide is exchanged, the carbon dioxide is removed from the blood plasma in the surrounding capillaries, where it begins it's process of expiration (breathing out).

How does oxygen gas help people with breathing difficulties?
body cells need oxygen, and need to get rid of carbon dioxide, so we inhale oxygen. the O2 is exchanged with CO2 in blood, and then, we exhale CO2. the O2 goes to the cells, and the cells give off CO2. then the blood carries the CO2 to the lunhs, and the cycle starts again.
Which gases will be exchanged in the stomata?
Oxygen and carbon dioxide. (O2) and (CO2)
Which organ is responsible for the removal of CO from the blood?
The lungs are responsible for the removal of carbon dioxide (CO2) from the blood. Oxygen is taken in through the lungs during inhalation and exchanged for carbon dioxide during exhalation. This process ensures the elimination of CO2 from the blood and the supply of fresh oxygen to the body.
Where are carbon dioxide and blood in the body?
CO2 exchanged to blood through capillaries and blood to alveoli
Why humans need hemoglobin to carry oxygen around the body?
haemoglobin contains Fe as central atom. Fe forms coordinate bond with O2 molecule and carry to the cells. Inside cell it diffuses into mitochondria where it is used to oxidation of alcohol into CO2 and H2O. The CO2 is ultimately enter into blood and carry to lungs via heart where it is exchanged for oxygen.
What are exchanged between the body cells and the blood plasma?
There are many substances they exchange, but the main ones are oxygen from the blood to the cells and CO2 from the cells to the blood.
Which two gases are exchanged in the lungs?
oxygen and carbon dioxide
What gases are exchanged in the lings during breathing?
The primary gases we breath are Oxygen (21%), Nitrogen (78%) and "others" (1%). The gases exchanged in the lungs are Carbon Dioxide (CO2) with Oxygen (O2)...red blood cells carry Oxygen to replace the CO2 that our body produces through metabolism, muscle movement and all other activity.141038-1110O

Where are oxygen and carbon dioxide exchanged in the body?
The alveoli sacks have many capillaries and the exchange occurs. O2 from the lungs hits the blood and CO2 is just given off.
Which gases will be exchanged in the stomata?
Oxygen and carbon dioxide. (O2) and (CO2)

What gasses are exchanged in the lungs?
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.
What are the two gases that are exchanged during the breathing process?
The function of the respiratory system is to exchange oxygen and carbon dioxide. You breath in air that is rich in oxygen and your lungs move it into the blood to go throughout your body. Then your lungs extract carbon dioxide from the blood and you breath it out.
Where are carbon dioxide and blood in the body?
CO2 exchanged to blood through capillaries and blood to alveoli
What substance needed by the body cells enters the body through the lungs?
O2 and Co2, but we breathe out the Co2 again + the O2 which is converted in more Co2
How the arteries that lead from your heart to your lungs different from the other arteries in your body?
the artieries that lead to your heart have carbon dioxide (Co2) in them and the arteries that lead to your body are carrying oxygen to the body parts
