Respiratory System And how it works

Tiny hairs called cilia protect the nasal passageways and other parts of the respiratory tract. They filter out dust and other particles that can get in the nose with the air. When you breath in and out, the cilia move back and forth in the nose.

The Anatomy Of The Nose

Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. Inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.

The Capillaries are blood vessels that carry blood and leads carbon dioxide from the alveoli.

Physics help us understand how both inhalation and exhalation depend on pressure gradients between the lungs and atmosphere. It also helps when you understand a certain way things move about.

Physics is a good tool for equations.
