Histology: practice question

The best answer is D, Simple squamous epithelium. Simple squamous type I pneumocytes provide a thin diffusion barrier in alveoli, allowing efficient exchange of oxygen and carbon dioxide.

Stratified squamous epithelium protects high-friction surfaces.

Transitional epithelium lines urinary tract.

Pseudostratified epithelium lines much of conducting airway.

It tests Histology in Anatomy. The correct option holds because: Correct: simple squamous cells minimize diffusion distance in alveoli.

We tag it as an application question: it asks you to use a fact on a patient or a finding. The tag is our own editorial judgement, not an official difficulty rating, so read the reason for every option, not only the answer.

Learn every nerve by its route, its muscles and what a lesion looks like at the bedside. That one habit answers a large share of questions. Then use the flashcards and the other Anatomy questions on this site to test what stuck.

No. It is an original practice item (editorial status: sample, version 1). NextPrep does not publish recalled or leaked questions, and independent faculty review of this item has not been completed yet, so confirm important facts in a standard textbook.
