Answer:
What are the tiny air sacs in the lungs called?
Your bronchioles are some of the smallest airways in your lungs. Inhaled air passes through tiny ducts from the bronchioles into elastic air sacs (alveoli). The alveoli are surrounded by the alveolar-capillary membrane, which normally prevents liquid in the capillaries from entering the air sacs.
What happens when we exhale (breathe out)?
When you breathe out, or exhale, your diaphragm and rib muscles relax,reducing the space in the chest cavity. As the chest cavity gets smaller, your lungs deflate, similar to the releasing of air from a balloon.
Which two structures does the trachea lead to in the lungs?
The windpipe (trachea) is the largest airway. The trachea branches into two smaller airways: the left and right bronchi, which lead to the two lungs.
