the paouch like air secs at the smallest lenchioles is called alveoli.the walls of alveoli are very thin and they are sorrounding thin blood capllaries .it is in alveoli exchange of gaseouse takes place there are so many alveoli in blood so they provides very larges surface srea for cxchanges of gaseouse
What else can I help you with?
Where in the lungs do you exchange gases?
In the lungs, exchange of gases occurs in the alveoli(sing: alveolus).
Where does the acual exchange of gasoccur?
The actual exchange of gases occurs in the alveoli
What process do alveoli participate in?
exchange of gases in respiratory
What are the small chambers of the lungs that are involved in the exchange of gases?
The alveoli are small sacs within the lungs where gas exchange occurs. They are located at the ends of bronchiole branches.
How would thick-walled alveoli affect the exchange of the respiratory gases?
lower exchange rate,takes longer for gases to diffuse
What gases can you infer are being exchange in the alveoli?
Oxygen and carbon dioxide
What process is responsible for the exchange of gases in the alveoli and the blood?
The difference in the partial pressure of the gases in the blood coming to the lungs and the alveoli mediated the gas exchange. Without this difference we wont be able to breathe. Diaphragm in the thoracic cavity plays an important role in exchange of these respiratory gases.
Where does the exchange of gases between blood air occur?
The exchange of gases between blood and air occurs in the alveoli of the lungs. Oxygen from the air diffuses into the bloodstream, while carbon dioxide from the blood diffuses into the air in the alveoli to be exhaled.
How are lungs designed in humans to maximise the area of exchange of gases?
Lungs consist of a series of tubes of ever-decreasing size, which carry air to and from the blood at the gas exchange surface in the 'alveoli'. These alveoli are microscopic hollow balls (at the ends of thousands of tubes) which are covered on the outside by blood capillaries (extremely narrow blood vessels) and a thin layer of mucus on the inside, which increases the speed at which the air diffuses into and out of the blood. The spherical shape of the alveoli, the microscopic width of these hollow balls (allowing more to fit within a small space) and the density of blood vessels inside the lungs all maximise the surface area. A last, important note: the lungs are NOT 'designed'; human lungs have evolved from simple gas exchange organs like the lungs of lungfish, becoming increasingly complex over a very long period of time.

The thin moist membrane through which humans exchange gases is found in the what?
alveoli
Why does simple squamous epithelium line the alveoli?
permits the easy exchange of gases
