How does the diaphragm pull air into and out of the lungs?
When the diaphragm expands, causes the lungs to become smaller forcing all the air in the lungs to be pushed out since there is more pressure. When the diaphragm contracts, it makes more room for the lungs to expand, forcing air in the lungs since there is more space.
Do lungs get smaller in the cold?
no
What are the small balloons in the lungs?
These are called alveoli.The bronchi (or air passages) continually divide into smaller and smaller bronchi in the lungs, until they become bronchioles. The very smallest of the bronchioles end in a tiny sac or 'balloon' called alveoli.The alveoli are surrounded by a dense network of capillaries which allows the exchange of gases between the lungs and the bloodstream.alveoli
How does the bronchi work?
A bronchus is a passage of airway in the respiratory tract that conducts air into the lungs. The bronchus branches into smaller tubes, which in turn become bronchioles.
What adaptations made it possible for vertebrates to become land dwellers?
Lungs, legs, major changes in renal function (water conservation), "dry" skin.
What causes air to enter the lungs?
The diaphragm, below the lungs, contracts causing a lower pressure in the lungs, and pulls the air in. To exhale, the diaphragm relaxes, and the chest muscles contract, forcing the lungs to be smaller and the air to be pushed out. While having sex, this happens faster as we need more energy. ah! ah! ah! oh! oh!oh!
Is it true that inside the lungs each bronchus divides into smaller and smaller tubes?
true
What are changes in kidneys or lungs called?
