Question 1

Which of the following best describes the principle of complementarity of structure and function?

Accepted Answer

Function always reflects structure, and what a structure can do depends on its specific form.

Question 2

A patient has a genetic mutation that causes their red blood cells to be sickle-shaped rather than disc-shaped. Which concept does this best illustrate?

Accepted Answer

The principle of complementarity of structure and function

Question 3

Which of the following is an example of negative feedback in the human body?

Accepted Answer

Regulation of blood glucose by insulin

Question 4

Which level of structural organization is correctly matched with its description?

Accepted Answer

Organ system level: organs that work closely together to accomplish a common purpose

Question 5

A scientist is studying the microscopic structure of liver tissue. Which field of anatomy is she working in?

Accepted Answer

Histology

Question 6

Which of the following is NOT a necessary life function?

Accepted Answer

Photosynthesis

Question 7

A person is exposed to a cold environment, causing their body temperature to drop. Which sequence correctly describes the negative feedback response?

Accepted Answer

Receptor detects cold → control center triggers heat production → effector causes shivering

Question 8

Which of the following best illustrates a positive feedback mechanism?

Accepted Answer

Enhancement of labor contractions by oxytocin

Question 9

Which survival need is most directly involved in the release of energy from food molecules?

Accepted Answer

Oxygen

Question 10

A patient is unable to maintain adequate atmospheric pressure in their lungs. Which survival need is most directly compromised?

Accepted Answer

Oxygen exchange

Question 11

Which of the following best describes the role of the effector in a homeostatic control system?

Accepted Answer

It provides the means to respond to a stimulus and carries out the control center's response.

Question 12

Which of the following is an example of a catabolic reaction in metabolism?

Accepted Answer

Breakdown of glucose to release energy

Question 13

A person has a fever of 40°C. Which of the following is a likely consequence if this temperature is sustained?

Accepted Answer

Disruption of homeostasis due to altered rates of chemical reactions

Question 14

Which of the following best describes the function of the plasma membrane in maintaining boundaries?

Accepted Answer

It separates the internal environment of the cell from the external environment.

Question 15

Which of the following is a correct sequence of the levels of structural organization in the human body, from simplest to most complex?

Accepted Answer

Chemical → Cell → Tissue → Organ → Organ system → Organism

Question 16

Which of the following is an example of how organ systems interrelate to maintain homeostasis?

Accepted Answer

The digestive system absorbs nutrients, which are then transported by the cardiovascular system to body cells.

Question 17

A person is unable to sweat due to a genetic disorder. Which necessary life function is most directly impaired?

Accepted Answer

Excretion

Question 18

Which of the following best explains why homeostatic imbalance increases the risk of disease?

Accepted Answer

It disrupts the stable internal environment required for normal cell function.

Question 19

Which of the following is a real-world example of the importance of anatomical terminology in healthcare?

Accepted Answer

A nurse uses precise anatomical terms to describe the location of a wound to a physician.

Question 20

Which of the following equations best represents the sum of all chemical reactions in the body (metabolism)?

Accepted Answer

$$	ext{Metabolism} = 	ext{Catabolism} + 	ext{Anabolism}$$
