Correct Answer is C
Explanation
A. The internal exchange of gases occurs at the tissue level, where oxygen is delivered to cells and carbon dioxide is removed. The diaphragm is not involved in this process.
B. Exhalation involves the relaxation of the diaphragm, which causes the lungs to compress and air to be expelled from the lungs.
C. During inhalation, the diaphragm contracts and moves downward, creating more space in the chest cavity, which allows the lungs to expand and air to flow in.
D. The external exchange of gases occurs in the lungs, where oxygen is transferred into the blood and carbon dioxide is removed, but it is not directly linked to diaphragm contraction.
Correct Answer is A
Explanation
A. The phrenic nerve is responsible for stimulating the diaphragm to contract and initiate breathing. It originates from the cervical spinal nerves (C3-C5) and plays a critical role in respiration.
B. The pons is a part of the brainstem involved in regulating breathing patterns but is not a nerve itself.
C. The sciatic nerve is the largest nerve in the body, primarily responsible for motor and sensory functions in the lower limbs, not for breathing.
D. The accessory nerve (Cranial Nerve XI) is involved in motor functions of the neck and shoulders, not the diaphragm.
