Accepted Answer

Muscle cells

Question 4

Which of the following is TRUE regarding exocrine glands?

Accepted Answer

They have ducts and secrete products onto epithelial surfaces

Question 5

Which equation correctly represents the relationship between total body water (TBW), intracellular fluid (ICF), and extracellular fluid (ECF)?

Accepted Answer

$$TBW = ICF + ECF$$

Question 6

A researcher is studying the movement of oxygen from the lungs to the tissues. Which organ systems are directly involved in this process? Select the BEST combination.

Accepted Answer

Respiratory, cardiovascular, and muscular systems

Question 7

Which of the following statements about epithelial cells is CORRECT?

Accepted Answer

They form sheet-like layers that cover surfaces and line hollow organs

Question 8

Which body fluid compartment contains the largest volume of water?

Accepted Answer

Intracellular fluid

Question 9

A hormone is released into the blood without passing through a duct. Which type of gland is responsible for this secretion?

Accepted Answer

Endocrine gland

Question 10

Which of the following is an example of homeostasis in the human body?

Accepted Answer

The release of erythropoietin from the kidneys in response to low oxygen levels

Question 11

Which of the following is NOT a function of connective tissue?

Accepted Answer

Generating electrical impulses

Question 12

Which of the following best describes the role of the plasma membrane in body fluid compartments?

Accepted Answer

It acts as a semipermeable barrier separating intracellular and extracellular fluids

Question 13

A patient has a total body water (TBW) of 42 L, with 28 L as intracellular fluid (ICF). What is the volume of extracellular fluid (ECF)?

Accepted Answer

$$ECF = TBW - ICF = 42\,L - 28\,L = 14\,L$$
