Inhalation (also known as inspiration) is the movement of air from the external environment, through the air ways, and into the alveoli.

Inhalation begins with the onset of contraction of the diaphragm, which results in expansion of the intrapleural space and an increase in negative pressure according to Boyle's Law. These negative pressure generates airflow because of the pressure difference between the atmosphere and alveolus. Air enters, inflating the lung through either the nose or the mouth into the pharynx (throat) and trachea before entering the alveoli.

Other muscles that can be involved in inhalation include:

How do you know if you have inhaled pot?
Q. One of my friends smoked pot with her mom the other day and she wasn't sure if she inhaled it. I want to know if she did because she's freaking out and hoping she didn't inhale. She said that she felt it in the back of her throat.

A. Wear a gas mask like the ones that protect you from toxic conditions at fires, or when asbestos is being removed from a place. You CAN'T clear your lungs of cigarette smoke. My friend, who never smoked a day in his life, was diagnosed with advanced lung cancer in February, and they only give him 3-5 months to live. It's impossible to find it until it's advanced. Yes, I AM trying to scare you.
