In an average adult with healthy lungs we find approximately 300 million alveoli with a total surface area approaching 150 meters square, or the size of a tennis court.

∙ 14y agoThe average human lung capacity as measured in surface area in the alveoli is about 3.000 square feet. That is about the size of a tennis court, or the floor space in two average three bedroom homes.

Where in the lungs does gas exchange happen?
AlveoliGaseous exchange takes place in the alveoli of the lung
What organ does oxygen pass from into the capillaries?
I believe its the alveoli in the lungs. These alveoli provide a large surface area for gaseous exchange.
Why do capillaries cover the alveoli?
Capillaries cover the alveoli in order to maximize the area for gas exchange between the lungs and the blood. Carbon dioxide is released from the blood through the capillary walls and into the alveoli, while oxygen is picked up from the alveoli through the capillary walls and into the blood.
What features of the alveoli mean that gas exchange is more efficient?
They Have A large surface area and they are full of red blood cells
Why do alveoli die in emphysema?
Destruction of alveoli reduces the surface area for gas exchange
Why is there large surface area for the alveoli?
The function of alveuli is to provide a surface for gas exchange. Therefore, a large surface area means that there is a lot of area for the gas exchange to take place. Therefore it is to improve efficiency of gas exchange in the lungs (exchanging carbon dioxide for oxygen). The large surface area is due to the shape of the alveoli- the have many small "pockets".
What is the part of alveoli in our body?
There are about 300 million alveoli in each of your lungs. These tiny air sacs provide an ideal site for the diffusion of gases into and out of the blood - also known as gaseous exchange. The alveoli have a very large surface area - in fact if all of the alveoli in your lungs were spread out flat they would cover the area of a tennis court. This large surface area is the result of all the alveoli being small spheres - it is another example of the importance of the surface area- to-volume ratio. If your lungs were simply two large balloon-like structures, the surface area wouldn't be big enough for you to get enough oxygen by diffusion to supply the needs of your cells. But each alveolus is a very tiny sphere. The smaller the radius of a sphere, the bigger the relative surface area - halving the radius increases the relative surface area by a factor of four. The millions of tiny alveoli in the human lungs are a very effective adaptation which provides a huge surface area for gaseous exchange into and out of the blood. The alveoli have a good air supply from the bronchioles and a rich blood supply. This is vital for successful gaseous exchange because it maintains a steep concentration gradient for oxygen from the air in the alveoli to the blood, and for carbon dioxide from the blood to the alveoli.
Organelle has a large amount of surface area?
The Alveoli
What organelle has a large amount of surface area?
The Alveoli
Why is 300 million alveoli in one pair of lungs?
The large number of alveoli increases the surface area over which gas exchange can occur, allowing the blood to become oxygenated more quickly.
What do alveoli have that enables them to absorb a large amount of oxygen?
A large surface area
What provide the greatest surface area for gas exchange?
Gas exchange occurs in the alveoli of the lungs.
