During which phase of respiration does the diaphragm relax? (2023)

Step 1: Understand that respiration has two main phases: inhalation and exhalation.
Step 2: Know that during inhalation, the diaphragm contracts and moves downwards, allowing air to enter the lungs.
Step 3: Recognize that during exhalation, the diaphragm relaxes and moves back up.
Step 4: Realize that when the diaphragm relaxes, the volume of the thoracic cavity decreases.
Step 5: Understand that this decrease in volume pushes air out of the lungs, completing the exhalation process.

Respiration Phases – Understanding the phases of respiration, specifically inhalation and exhalation, and the role of the diaphragm in these processes.
Diaphragm Function – Knowledge of how the diaphragm's contraction and relaxation affect lung volume and airflow.
