Question 1

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

Accepted Answer

Anatomy focuses on the structure of the human body, while physiology focuses on how those structures function.

Question 2

A student is asked to identify the plane that divides the body into anterior and posterior sections. Which plane should they select?

Accepted Answer

Frontal (coronal) plane

Question 3

During a physical examination, a doctor uses palpation. What is the doctor doing?

Accepted Answer

Feeling body parts to examine size, consistency, texture, location, and tenderness

Question 4

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

Accepted Answer

Cell, tissue, organ, organ system, organism

Question 5

Which of the following is an example of a negative feedback mechanism in human physiology?

Accepted Answer

Regulation of body temperature

Question 6

A runner’s blood CO$_2$ level rises during exercise. Which component of the homeostatic control system detects this change?

Accepted Answer

Receptor

Question 7

Which of the following is the set point for normal human body temperature?

Accepted Answer

37°C (98.6°F)

Question 8

In the homeostatic control of body temperature, which of the following acts as the effector?

Accepted Answer

Blood vessels and sweat glands

Question 9

Which of the following best describes the response in the negative feedback loop for thermoregulation?

Accepted Answer

Vasodilation and increased sweating

Question 10

Which of the following is TRUE regarding positive feedback mechanisms?

Accepted Answer

They accelerate the process and amplify the initial stimulus.

Question 11

A patient is experiencing a homeostatic imbalance in blood pH. Which principle explains why this can lead to disease?

Accepted Answer

Homeostasis maintains variables within a narrow range; failure to do so disrupts equilibrium and can result in disease.

Question 12

Which of the following is a correct example of extrinsic regulation?

Accepted Answer

The nervous and endocrine systems control responses throughout the body.

Question 13

Which of the following is the correct formula for calculating the average of a set of values $x_1, x_2, ..., x_n$?

Accepted Answer

$\frac{x_1 + x_2 + ... + x_n}{n}$

Question 14

Which of the following is NOT a core property shared by all living organisms?

Accepted Answer

Secretion

Question 15

A student is asked to paraphrase information from a textbook for a case study assignment. What is the proper way to cite this information?

Accepted Answer

Paraphrase and provide MLA/APA reference

Question 16

Which of the following best describes the anatomical position?

Accepted Answer

Standing erect, facing the observer, arms at sides, palms facing forward, feet flat on the floor

Question 17

Which body cavity protects the brain?

Accepted Answer

Cranial cavity

Question 18

Which of the following is a real-life example of a homeostatic response involving the respiratory system?

Accepted Answer

Increased respiratory rate to exhale excess CO$_2$ during exercise

Question 19

Which of the following is the correct order of components in a homeostatic control system?

Accepted Answer

Variable → Receptor → Control Center → Set Point → Effector → Response

Question 20

Which of the following best explains why physiological systems must integrate to maintain homeostasis?

Accepted Answer

Because opposing forces must be balanced to maintain equilibrium and prevent disease.
