Zebras breathe the same way that all mammals do. They have lungs, a trachea, and bronchioles. Zebras inhale through their nose or mouth. The air goes down the trachea and branches into bronchi and bronchioles. Oxygen and carbon dioxide pass across the cell membranes inside the alveoli of the bronchioles. The zebra then exhales out of their nose or mouth.
when you breath in oxygen, it goes through the bronchi in your lungs, through the bronchioles and then to the alveoli from there it goes to the capillaries where the oxygen dissolves into the blood through tissue that is one cell thick. as that happens, the carbon dioxide that is in your blood already, dissolves out into the alveoli. then it travels through the bronchioles, bronchi, and to your lungs, then out your nose.
Neither, alveoli are the air sacs within the lungs in mammals (singular alveolus).
Which of these have very thin cell membranes?
An individual air cell is called an alveolus (plural: alveoli) in the lungs. Alveoli are tiny air sacs where gas exchange occurs during the process of breathing.
Stratified: I disagree with stratified, the answer is "simple" arrangement.
In the lungs are small air sacs called alveoli. These alveoli are covered with blood capillaries. Oxygen and Carbon Dioxide diffuse through the alveolar capillary membrane. Oxygen diffuses from the alveoli to the blood capillary and carbon dioxide diffuses from the capillary to the alveoli and you breath it out of your body.
The membrane of the alveolus, the air sacs in the lungs where this process takes place, is only one cell thick. The wall of the capillary running adjacent to the alveolus is also one cell thick, so the gases are exchanged between the alveolus and the capillary cell membranes.
tumors usually start to develop in the central bronchi. They grow quickly and prevent the lungs from functioning at their full capacity. Tumors may block the movement of air through the bronchi in the lungs
In the alveoli, which are the tiny air sacs in the lungs, oxygen moves from the air into the blood and carbon dioxide moves from the blood into the air. This gas exchange occurs through diffusion across the thin walls of the alveoli and capillaries.
Diffusion along the (partial) pressure gradient.
