Question 1

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

Accepted Answer

Anatomy is the study of the structure of body parts and their relationships, while physiology is the study of how those parts function to carry out life-sustaining activities.

Question 2

A researcher is investigating how the heart pumps blood through the body. Is this study more related to anatomy or physiology, and why?

Accepted Answer

Physiology, because it involves the function of the heart in pumping blood.

Question 3

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

Accepted Answer

Chemical, cellular, tissue, organ, organ system, organismal

Question 4

A patient is unable to maintain a stable internal body temperature. Which concept does this scenario best illustrate?

Accepted Answer

Homeostatic imbalance

Question 5

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

Accepted Answer

Regulation of blood glucose by insulin

Question 6

In a homeostatic control system, what is the role of the effector?

Accepted Answer

To provide the means for the response to the stimulus

Question 7

A person is standing with their body erect, feet slightly apart, and palms facing forward with thumbs pointing away from the body. What is this position called, and why is it important?

Accepted Answer

Anatomical position; it provides a standard reference for anatomical terminology

Question 8

Which of the following best describes the sagittal plane?

Accepted Answer

Divides the body into right and left parts

Question 9

A cut made perfectly on the midline of the body would result in which type of section?

Accepted Answer

Midsagittal (median) section

Question 10

Which of the following is NOT a necessary life function for humans?

Accepted Answer

Photosynthesis

Question 11

If a person is dehydrated, which homeostatic mechanism is triggered first?

Accepted Answer

Negative feedback causing thirst and fluid intake

Question 12

Which of the following best explains why oxygen is a survival need for humans?

Accepted Answer

It is required for the release of energy from food molecules.

Question 13

A patient has a deep wound on the anterior surface of the forearm. Which directional term best describes the location of the wound relative to the skin?

Accepted Answer

Deep

Question 14

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

Accepted Answer

Labor contractions during childbirth

Question 15

Which of the following best describes the function of the control center in a homeostatic control system?

Accepted Answer

It determines the set point and analyzes input to determine the appropriate response.

Question 16

A cross section of the body that divides it into superior and inferior parts is made along which plane?

Accepted Answer

Transverse (horizontal) plane

Question 17

Which of the following is a correct sequence of events in a negative feedback mechanism regulating blood glucose?

Accepted Answer

Blood glucose rises → pancreas releases insulin → cells absorb glucose → blood glucose falls

Question 18

Which of the following best describes the relationship between the elbow and the wrist?

Accepted Answer

The elbow is proximal to the wrist.

Question 19

A patient is experiencing heart failure due to the breakdown of homeostatic mechanisms. Which of the following best explains this situation?

Accepted Answer

Homeostatic imbalance has overwhelmed negative feedback, leading to destructive positive feedback mechanisms.

Question 20

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

Accepted Answer

Excessive atmospheric pressure
