The dome-shaped muscle that lies below the lungs and is important in the breathing process is the
A. alveoli.
B. asthma.
C. bronchi.
D. diaphragm.
D. Diaphragm.
The correct answer is D. diaphragm.
The correct answer is D. diaphragm.
To find the answer, you can try the following steps:
1. Understand the question: The question is asking for the dome-shaped muscle that is located below the lungs and plays a role in the breathing process.
2. Review the options: Look at the options provided and consider which one could match the description given in the question.
- Alveoli: Alveoli are tiny sacs located in the lungs where gas exchange occurs. They are not a muscle and are not located below the lungs, so this option is not correct.
- Asthma: Asthma is a chronic respiratory condition characterized by difficulty breathing. It is not a muscle and is not located below the lungs, so this option is not correct.
- Bronchi: The bronchi are the main air passages that branch off from the trachea and lead into the lungs. They are not a muscle and are not located below the lungs, so this option is not correct.
- Diaphragm: The diaphragm is a flat, dome-shaped muscle located below the lungs and above the abdomen. It plays a crucial role in the breathing process by contracting and relaxing, causing the lungs to expand and contract. This option matches the description given in the question and is therefore correct.
3. Select the correct answer: Based on the analysis above, the correct answer is D. diaphragm, as it fits the description provided in the question.
