Lungs

Which of these have very thin cell membranes?
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).
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.
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 Carbon Dioxide is not absorbed into the blood it is only the oxygen. When you breathe in, the air travels down your windpipe, down the bronchi and then down the bronchis. On the end of the bronchioles, there are sacs called alveoli. These have a good blood supply surrounding them. The blood is absorbed through this small sac. The reason it can get through is that the walls of the alveoli are only one cell thick.
Diffusion along the (partial) pressure gradient.
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
Blood capillaries surrounding air sacs called alveoli.
The lungs are similar to a cell membrane in the sense that oxygen enters the alveoli similarly to how it enters cells.
