During inspiration, external intercostal muscles and diaphragm contract.
Explanation:
- Inspiration is the process of inhaling or breathing in air into the lungs.
- During inspiration, the diaphragm and external intercostal muscles contract.
- The diaphragm is a dome-shaped muscle located at the base of the lungs, and the external intercostal muscles are located between the ribs.
- When these muscles contract, they cause the volume of the thoracic cavity to increase, which leads to a decrease in the pressure inside the lungs.
- As a result, air flows from an area of higher pressure outside the body into an area of lower pressure inside the lungs, filling them with air.
Option A is therefore the correct answer.
