which divides into two bronchi, each of which enters a lung. The bronchi divide and subdivide into a network of countless tubules. The smallest tubules, or bronchioles, enter cup-shaped air sacs known as alveoli, which number about 700 million in both lungs. Each alveolus is surrounded by a...
trachea -rigid tube that connects the mouth with the bronchi (windpipe) Breathing and the Autonomic Nervous System You don't have to think about breathing because your body's autonomic nervous system controls it, as it does many other functions in your body. If you try to hold your breath...
The trachea is divided at its base into two airways called the bronchi, which lead to each lung. The bronchi split like the branches of a tree into tens of thousands of smaller airways called bronchioles, which connect to tiny air sacs called alveoli. This Article Improved My Health Changed ...

Water and oxygen can move across the membrane of the alveoli in the lungs. How do their paths through the alveoli cell membrane differ? Why do the walls of the alveoli need to be thin? What structures in the mouth are important in the respiratory system?
The Alveoli in Your Lungs. Alveoli are tiny air sacs in your lungs that take up the oxygen you breathe in and keep your body going. Although they're microscopic,
The bronchi further divide into smaller branches (bronchioles) that are situated within the lungs. From here air finally reaches its destination, the alveoli (alveolus in singular), which are small air sacs resembling small grape-like clusters. It is in these small air sacs that blood and...
Smoking also damages the alveoli, the tiny air sacs that bring oxygen into your body. Once they’re destroyed, they don’t growback. When you lose too many of them you’ll haveemphysema, a lung condition that causes severe shortness of breath. ...
