Q
Q: What is the primary muscle involved in the process of inhalation?
Solution:
The diaphragm contracts and moves downward, increasing the thoracic cavity volume and allowing air to flow into the lungs.
Steps: 7
Show Steps
Step 1: Understand that inhalation is the process of taking air into the lungs.
Step 2: Identify the main muscle used during inhalation, which is the diaphragm.
Step 3: Know that the diaphragm is a dome-shaped muscle located at the bottom of the ribcage.
Step 4: When you inhale, the diaphragm contracts (tightens) and moves downward.
Step 5: This downward movement increases the space in the chest (thoracic cavity).
Step 6: As the thoracic cavity volume increases, air is drawn into the lungs.
Step 7: This process allows your body to take in oxygen from the air.
