Question 1

Which of the following best describes the main difference between exocrine and endocrine glands?

Accepted Answer

Exocrine glands use ducts to secrete products onto body surfaces or cavities, while endocrine glands secrete hormones directly into the bloodstream.

Question 2

A mother breastfeeding her infant is utilizing which type of gland for milk production?

Accepted Answer

Exocrine gland

Question 3

Which of the following is a primary function of goblet cells?

Accepted Answer

Lubricating and protecting the epithelium by secreting mucus

Question 4

If you had many more goblet cells than normal, which symptom would you most likely experience?

Accepted Answer

Excess mucus production

Question 5

Which type of multicellular gland needs to be completely regenerated each time it secretes product?

Accepted Answer

Holocrine

Question 6

Which type of gland does NOT need to be repaired at all after secretion?

Accepted Answer

Merocrine

Question 7

Which mode of secretion is most consistent with how goblet cells secrete?

Accepted Answer

Merocrine

Question 8

Which of the following best describes the secretion process of merocrine glands?

Accepted Answer

Products are released by exocytosis without damaging the cell.

Question 9

Which gland type is responsible for secreting hormones that can affect distant organs?

Accepted Answer

Endocrine gland

Question 10

A patient presents with oily skin due to overactive sebaceous glands. Which mode of secretion is involved?

Accepted Answer

Holocrine

Question 11

Which of the following equations best represents the process of exocytosis in merocrine secretion?

Accepted Answer

$$\mathrm{Secretory\ vesicle} \rightarrow \mathrm{Cell\ membrane} \rightarrow \mathrm{Product\ release}$$

Question 12

Which of the following is NOT a characteristic of endocrine glands?

Accepted Answer

They use ducts to transport their products.

Question 13

Which cell organelle is most directly involved in the secretion of mucus by goblet cells?

Accepted Answer

Golgi apparatus

Question 14

Which of the following best explains why holocrine glands need to be regenerated after secretion?

Accepted Answer

The entire cell ruptures and is destroyed during secretion.

Question 15

Which of the following is a real-world example of a merocrine gland?

Accepted Answer

Salivary gland

Question 16

Which type of secretion involves only a portion of the cell being shed to release product?

Accepted Answer

Apocrine

Question 17

Which of the following best describes the function of multicellular exocrine glands?

Accepted Answer

They secrete products onto body surfaces or into body cavities via ducts.

Question 18

Which of the following is a plausible consequence of defective goblet cells in the respiratory tract?

Accepted Answer

Reduced mucus secretion leading to increased risk of infection

Question 19

Which of the following best describes the role of microvilli in goblet cells?

Accepted Answer

They increase the surface area for absorption and secretion.

Question 20

Which of the following best matches the equation for holocrine secretion?

Accepted Answer

$$\mathrm{Cell\ rupture} \rightarrow \mathrm{Product\ release}$$
