Which of the following is a correct pairing of epithelial tissue type and its primary location in the body?

Accepted Answer

Simple squamous epithelium – alveoli of the lungs

Question 4

Which of the following statements about the basement membrane is TRUE?

Accepted Answer

It is composed of proteins secreted by both epithelial and connective tissue cells.

A patient has a genetic defect affecting collagen production. Which tissue type would be most directly affected?

Accepted Answer

Connective tissue

Question 6

Which of the following best explains why cartilage heals slowly after injury?

Accepted Answer

Cartilage lacks blood vessels, limiting nutrient and waste exchange.

Question 11

Gap junctions are especially important in which of the following tissues for coordinated contraction?

Accepted Answer

Cardiac muscle

Question 12

Which of the following best describes the role of negative feedback in homeostasis?

Accepted Answer

It maintains a constant internal environment by counteracting deviations from a set point.

Question 13

Accepted Answer

Core body temperature

Question 14

Which of the following is NOT a function of the integumentary system?

Accepted Answer
