Answered by chouhanpushpraj44

Explanation:

Inspiration is the process of inhaling oxygen. When we breathe in, the diaphragm contracts and moves downward. This increases the space in the chest cavity into which our lungs expand. Thus, the intercostal muscles between the ribs enlarge the chest cavity.
