Where does the actual air exchange take place in the lungs?
The actual air exchange takes place in the alveoli of the lungs
What is 'gaseous exchange'?
Gaseous exchange is the movement of oxygen in the body, it takes place in the lungs through diffusion by the alveolar surface. There are millions of alveloi in the lungs, which gives it around 70m2 of exchange surface.
What surrounds the alveoli in the lungs to allow gas exchange to occur?
Capillaries
How are the lungs and the capillaries connected?
The lungs contain air sacs called alveoli which are surrounded by blood capillaries to allow gaseous exchange.
What is avieoli?
they are tiny air sacs in the lungs that allow the exchange between oxygen and carbon dioxide.
What duty do the lungs perform?
They allow gaseous exchange between the inhaled oxygen and the exhaled carbon dioxide.
What job is the lungs allow the blood to do?
Exchange oxygen and carbon dioxide in the alveoli of the lung, then transfer it to the heart
Where does the exchanged of gases in the body take place?
Gas exchange between the body and the environment occurs in the lungs.
Why does human lungs need thin permeable walls?
To allow for gas exchange, i.e. oxygen and carbon dioxide.
In the lungs oxygen from air enters what?
Oxygen in the lungs and passes through the alveoli, small sacs which allow gas exchange, and enters the blood to be pumped throughout the body.
Where in the lungs do you exchange gases?
In the lungs, exchange of gases occurs in the alveoli(sing: alveolus).
What are the structures that allow for the exchange of oxygen and carbon dioxide between the lungs and blood?
The tiny air sacs of the lungs were oxygen and carbon dioxide are exchanged are the alveoli.
