B. The main muscle used in breathingExplanation
The correct answer is "the main muscle used in breathing." The diaphragm is a dome-shaped muscle located below the lungs that plays a crucial role in the process of breathing. When we inhale, the diaphragm contracts and moves downward, creating more space in the chest cavity and allowing the lungs to expand and fill with air. When we exhale, the diaphragm relaxes and moves upward, pushing air out of the lungs. Therefore, the diaphragm is the primary muscle responsible for the mechanical aspect of breathing.Rate this question:

Without an adequate supply of oxygen, our body's cells would not be able to function properly, leading to organ damage and eventually death.Rate this question:

Correct Answer
A. DiaphragmExplanation
The diaphragm is the main breathing muscle because it plays a crucial role in the process of inhalation and exhalation. When we inhale, the diaphragm contracts and moves downward, creating more space in the chest cavity for the lungs to expand and fill with air. This allows us to take in oxygen. On the other hand, when we exhale, the diaphragm relaxes and moves upward, pushing the air out of the lungs. Without the diaphragm's contraction and relaxation, the process of breathing would not be possible.Rate this question:
