A patient has a mutation affecting the structure of simple squamous epithelium in their alveoli. Which function is most likely impaired?

Accepted Answer

Rapid diffusion of gases

Question 4

Which of the following best describes the difference between merocrine and holocrine gland secretion?

Accepted Answer

Merocrine glands release their product by exocytosis; holocrine glands release their product by cell rupture.
