Stratified: I disagree with stratified, the answer is "simple" arrangement.
From the windpipe, the air moves through two large passageways, called the bronchi. A complex system of much smaller tubes or bronchioles branch out from your bronchi to carry oxygen to the "working parts" of the lungs - the millions of air sacs or alveoli thanks :0
The skin of amphibians is made of that kind of epithelium, but mostly, they are found in capillaries (circulatory system) and alveoli (lung), they are needed where it is necessary to have rapid exchange by diffusion.

Only whales have lungs .No other fish has lungs they have gills.
you will get a lungs cancer
Kind of sponge-like.
We should first start at the beginning. As you know, you breathe oxygen in when you contract your diaphragm and air fills your lungs. The walls of your lungs are filled with capillaries (tiny blood vessels) that look kind of like feathers. If you were to stretch out the entire surface area of the capillaries in your lungs, it would be about equal to the size of a tennis court! So, in the capillaries flows your de-oxygenated blood. It has been on a complete cycle through your body, and is now low on O2. When the erythrocytes (red blood cells) enter the capillaries, the oxygen gets chemically stuck to them. It attaches to a large protein called hemoglobin, a 4 piece protein with a single iron atom at the center. (this explains why an iron deficiency can lead to anemia, or a low red blood cell count) Each red blood cell contains as many, many hemoglobin molecules. The oxygen is at a HIGH concentration in your lungs, and so flows into the LOW concentration in the blood. As the laws of nature would predict, as the red blood cells move into areas of lower oxygen concentration, the oxygen leaves the hemoglobin and enters its new tissue.
A potato is not a cell, so a potato is not any kind of cell.
A crystal.

Smoking and Drinkin have a bad effect on the lungs in the long term :) x
Alveoli are covered with capillaries. The deoxygenated blood that has come into the lung through the arteries flows through these capillaries, getting rid of carbon dioxide and accepting oxygen from the air that has been brought into the alveoli by the bronchioles. The carbon dioxide travels back out of the alveoli, through the bronchioles, into the bronchial tube system, and out the trachea each time you exhale.
