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

$$\text{Metabolism} = \text{Catabolism} + \text{Anabolism}$$

Question 1

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

Accepted Answer

Structure and function are interrelated; the form of a body part enables its function.

Question 2

Which subdivision of anatomy focuses on the study of tissues using a microscope?

Accepted Answer

Histology

Question 3

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

Accepted Answer

Responsiveness

Question 4

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

Accepted Answer

Chemical, cell, tissue, organ, organ system, organism

Question 5

Which of the following best describes homeostasis?

Accepted Answer

The process by which the body maintains a constant internal environment despite external changes.

Question 6

A person running a marathon in hot weather begins to sweat profusely. Which component of the homeostatic control system is responsible for producing sweat?

Accepted Answer

Effector

Question 7

Which of the following is NOT a survival need for humans?

Accepted Answer

Excessive sunlight

Question 8

Which body system is primarily responsible for transporting oxygen and nutrients to tissues and removing wastes?

Accepted Answer

Cardiovascular system

Question 9

A broken arm impacts which body systems the most, and why?

Accepted Answer

Skeletal and muscular systems, because the skeletal system provides structure and the muscular system enables movement.

Question 10

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

Accepted Answer

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

Question 11

Which of the following best describes negative feedback in homeostatic regulation?

Accepted Answer

A response that reduces or shuts off the original stimulus.

Question 12

A person with a fever of 40°C is at risk because:

Accepted Answer

Chemical reactions in the body may speed up to dangerous levels.

Question 13

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

Accepted Answer

Blood clotting after injury

Question 14

Which subdivision of physiology would most likely study the effects of a heart attack on blood flow?

Accepted Answer

Cardiovascular physiology

Question 15

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

Accepted Answer

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

Question 16

A person touches a hot stove and immediately withdraws their hand. Which necessary life function is demonstrated?

Accepted Answer

Responsiveness

Question 17

Which of the following is a correct statement about the relationship between anatomy and physiology?

Accepted Answer

Anatomy and physiology are inseparable because structure determines function.

Question 18

Which of the following is an example of an anabolic reaction?

Accepted Answer

Synthesizing proteins from amino acids

Question 19

Which organ system is primarily responsible for removing metabolic wastes from the body?

Accepted Answer

Urinary system

Question 20

A climber at high altitude experiences difficulty breathing due to low atmospheric pressure. Which survival need is most directly affected?

Accepted Answer

Appropriate atmospheric pressure
