Question 1

Which of the following best describes the difference between anatomy and physiology?

Accepted Answer

Anatomy is the study of body structure, while physiology is the study of body function.

Question 2

Which level of structural organization is immediately above the tissue level in the human body?

Accepted Answer

Organ level

Question 3

A patient is experiencing a homeostatic imbalance resulting in elevated blood glucose levels. Which life function is most directly affected?

Accepted Answer

Metabolism

Question 4

Which of the following is an example of a positive feedback mechanism in the human body?

Accepted Answer

Blood clotting after a vessel injury

Question 5

Which macromolecule is correctly matched with its monomer?

Accepted Answer

Nucleic acids — nucleotide bases

Question 6

A patient with a severe burn has lost the ability to maintain boundaries. Which structure is primarily responsible for this life function?

Accepted Answer

Cell membrane

Question 7

Which organ system is primarily responsible for transporting nutrients, gases, and wastes throughout the body?

Accepted Answer

Cardiovascular system

Question 8

Which of the following best describes the role of serous membranes in the ventral body cavity?

Accepted Answer

They produce serous fluid to reduce friction between organs.

Question 9

A patient is injected with a radioactively labeled glucose for a PET scan. What is the principle behind this imaging technique?

Accepted Answer

It visualizes metabolically active tissues by detecting radioactive emissions.

Question 10

Which of the following equations correctly represents the breakdown of a triglyceride during digestion?

Accepted Answer

$$\mathrm{C_3H_5(O_2CR)_3} + 3\ H_2O \rightarrow \mathrm{C_3H_8O_3} + 3\ \mathrm{RCOOH}$$

Question 11

Which imaging technique is most suitable for detecting soft tissue injuries in the brain?

Accepted Answer

Magnetic resonance imaging (MRI)

Question 12

Which of the following best illustrates the concept of negative feedback in homeostasis?

Accepted Answer

A rise in blood glucose triggers insulin release, lowering blood glucose.

Question 13

Which life function is most directly associated with the absorption of nutrients from digested food?

Accepted Answer

Digestion

Question 14

A patient with kidney failure is unable to remove metabolic wastes from the blood. Which life function is compromised?

Accepted Answer

Excretion

Question 15

Which of the following is NOT a necessary life function?

Accepted Answer

Homeostasis

Question 16

Which organ system is primarily responsible for producing hormones that regulate other body functions?

Accepted Answer

Endocrine system

Question 17

Which of the following best describes the anatomical position?

Accepted Answer

Standing with arms at sides and palms facing forward

Question 18

Which plane divides the body into right and left halves?

Accepted Answer

Median (midsagittal) plane

Question 19

Which of the following body cavities is NOT exposed to the external environment?

Accepted Answer

Synovial cavity

Question 20

Which of the following best explains why homeostasis is described as a 'dynamic equilibrium'?

Accepted Answer

Variables fluctuate within a narrow range around a set point.
