Which route of entry could chemicals use to enter through the body’s airways? a. absorption b. ingestion c. inhalation d. injection

Correct answer choice is :

When you breathe in, or inhale, your diaphragm contracts and moves down. This raises the space in your chest hollow, into which your lungs grow. The intercostal tissues between your ribs also help expand the chest cavity. They contract to pull your rib crate both upward and outside when you inhale.
