Rationale: Goblet cells in the respiratory tract secrete mucus, which traps debris and pathogens, protecting the lungs as part of the mucociliary clearance system.

Correct Answer: A

Rationale: Fatigue and dyspnea are early signs of hypoxia as the body struggles to oxygenate tissues, prompting increased respiratory effort.

Correct Answer: C

Rationale: A pregnant individual has the highest caloric needs due to fetal growth and increased maternal metabolism.
