How are the lungs designed in human beings to maximise the area for 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 site for exchange of gases in human beings is the?
alveoli
What is the function of simple tissues?
They are designed to exchange materials such as the alveoli exchange gases or the capillary walls exchange fluid and nutrients with the intestitial tissues.
What is the function of simple epithelial tissues?
They are designed to exchange materials such as the alveoli exchange gases or the capillary walls exchange fluid and nutrients with the intestitial tissues.
How are the alveoli designed to maximise the exchange of gases?
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
Where in the lungs do you exchange gases?
In the lungs, exchange of gases occurs in the alveoli(sing: alveolus).
Where does the exchange of gases occur in the plant?
During the stage of photosynthesis, the exchange of gases occur in the leaves.

Exchange of gases?
perfusion
How can leafs exchange gases in the absence of light?
Light is necessary for the exchange of gases in plants.æ Light is what instigates photosynthesis and without photosythesis there can be no gas exchange.
What blood vessels do the exchange of gases occur?
the blood vessel which allows gas exchange to occur is the capillaries
Where does the acual exchange of gasoccur?
The actual exchange of gases occurs in the alveoli
Do you exchange gases in the lungs?
YES
