Question 1

Which statement best explains the relationship between anatomy and physiology?

Accepted Answer

Anatomy studies the structure of the body, and physiology studies how those structures function; structure determines function.

Question 2

A patient has damaged thin-walled air sacs in their lungs. Which physiological process is most likely impaired?

Accepted Answer

The exchange of gases, such as oxygen and carbon dioxide, due to reduced surface area for diffusion.

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

Which organ system is primarily responsible for regulating emotions and bodily functions through hormone production?

Accepted Answer

Endocrine system

Question 5

A person is unable to maintain normal body temperature and is at risk of hypothermia. Which survival need is most directly compromised?

Accepted Answer

Normal body temperature

Question 6

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

Accepted Answer

Sweating to lower body temperature when overheated

Question 7

If the hypothalamus detects low blood sugar, which part of the homeostatic control system is it acting as?

Accepted Answer

Control center

Question 8

Which organ system is responsible for distributing nutrients, gases, and waste throughout the body?

Accepted Answer

Cardiovascular system

Question 9

A person is unable to expel waste and balance water and electrolytes. Which organ system is most likely malfunctioning?
