Question 1

Which statement best describes the principle of complementarity of structure and function in human anatomy and physiology?

Accepted Answer

Structure and function are interdependent; the function of a body part depends on its structure, and vice versa.

Question 2

A patient is experiencing rapid blood loss. Which feedback mechanism is most likely to be activated, and what is its effect?

Accepted Answer

Positive feedback; it accelerates blood clotting until the bleeding stops.

Question 3

Which of the following correctly lists the levels of structural organization in the human body from simplest to most complex?

Accepted Answer

Atom, molecule, cell, tissue, organ, organ system, organism

Question 4

Which organ system is primarily responsible for regulating long-term changes in the body, such as growth and metabolism?

Accepted Answer

Endocrine system

Question 5

A person is standing upright, facing forward, with arms at the sides and palms facing forward. This describes which anatomical position?

Accepted Answer

Anatomical position

Question 6

Which of the following is NOT a functional characteristic necessary to maintain life in humans?

Accepted Answer

Digestion of food only in the stomach

Question 7

Which of the following elements forms the bulk of body matter?

Accepted Answer

Carbon, hydrogen, oxygen, nitrogen

Question 8

A molecule of water ($$\mathrm{H}_2\mathrm{O}) is $$held together by which type of chemical bond?

Accepted Answer

Covalent bond

Question 9

Which of the following best describes an oxidation-reduction (redox) reaction?

Accepted Answer

A reaction in which atoms exchange electrons, resulting in one atom being oxidized and another reduced.

Question 10

Which factor would NOT increase the rate of a chemical reaction in the human body?

Accepted Answer

Decreasing the surface area of reactants

Question 11

Which of the following is a correct description of the relationship between homeostatic imbalance and disease?

Accepted Answer

Homeostatic imbalance can lead to disease if the body's regulatory mechanisms fail to restore balance.

Question 12

Which of the following is a decomposition reaction?

Accepted Answer

$$\mathrm{AB} \rightarrow \mathrm{A} + \mathrm{B}$$

Question 13

Which body cavity contains the heart and lungs?

Accepted Answer

Thoracic cavity

Question 14

Which of the following best describes the general structure of carbohydrates?

Accepted Answer

Monosaccharide units linked together by glycosidic bonds

Question 15

Which of the following is a correct formula for calculating atomic mass?

Accepted Answer

$$	ext{Atomic mass} = 	ext{Number of protons} + 	ext{Number of neutrons}$$

Question 16

Which of the following best describes the action of enzymes?

Accepted Answer

Enzymes decrease the activation energy, speeding up chemical reactions.

Question 17

Which of the following is a correct description of a base?

Accepted Answer

A substance that releases hydroxide ions ($$\mathrm{OH}^-) in $$solution.

Question 18

Which of the following is a real-life example of an exchange reaction in the human body?

Accepted Answer

The reaction between hydrochloric acid ($$\mathrm{HCl}) $$and sodium bicarbonate ($$\mathrm{NaHCO}_3) to $$form sodium chloride ($$\mathrm{NaCl}$$), carbon dioxide ($$\mathrm{CO}_2$$), and water ($$\mathrm{H}_2\mathrm{O})$$

Question 19
