Question 1

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

Accepted Answer

Anatomy is the study of structure, and physiology is the study of function; structure determines function.

Question 2

A patient is unable to maintain a stable internal body temperature. Which necessary life function is most directly impaired?

Accepted Answer

Homeostasis

Question 3

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

Accepted Answer

Regulation of blood glucose by insulin

Question 4

A person is exposed to a cold environment, causing their body temperature to drop. Which of the following best describes the homeostatic response?

Accepted Answer

Effectors such as muscles generate heat by shivering to restore normal temperature.

Question 5

Which of the following best illustrates the concept of positive feedback?

Accepted Answer

Amplification of uterine contractions during labor

Question 6

A scientist is studying the microscopic structure of liver cells. Which subdivision of anatomy is she most likely using?

Accepted Answer

Cytology

Question 7

Which of the following is NOT a necessary life function?

Accepted Answer

Photosynthesis

Question 8

A patient has a disease that prevents the breakdown of nutrients in the digestive tract. Which life function is most directly affected?

Accepted Answer

Digestion

Question 9

Which of the following best describes the role of the control center in a homeostatic mechanism?

Accepted Answer

Determines the set point and analyzes information to determine the appropriate response.

Question 10

Which of the following is a correct example of a survival need and its function?

Accepted Answer

Water: involved in metabolic reactions and makes up 60-80% of body weight

Question 11

A patient with diabetes has difficulty regulating blood glucose levels. Which homeostatic mechanism is failing?

Accepted Answer

Negative feedback

Question 12

Which of the following best explains why water is considered a survival need?

Accepted Answer

It is required for chemical reactions and makes up a large portion of body weight.

Question 13

Which of the following scenarios best demonstrates the concept of 'structure determines function'?

Accepted Answer

The flexible structure of red blood cells allows them to squeeze through capillaries.

Question 14

Which of the following is an example of a gross anatomical study?

Accepted Answer

Studying the structure of the heart as seen during surgery

Question 15

A person is unable to respond to changes in their environment, such as moving their hand away from a hot surface. Which necessary life function is impaired?

Accepted Answer

Responsiveness

Question 16

Which of the following best describes the process of metabolism?

Accepted Answer

All chemical reactions that occur within the body, including catabolism and anabolism

Question 17

If the set point for body temperature is $$37^\circ C$$, and the body temperature rises to $$39^\circ C$$, which homeostatic process will occur?

Accepted Answer

Negative feedback will activate mechanisms to lower the temperature.

Question 18

Which of the following is a correct sequence of events in a typical negative feedback loop?

Accepted Answer

Receptor → Control Center → Effector

Question 19

A patient is unable to eliminate metabolic wastes from their body. Which necessary life function is most directly affected?

Accepted Answer

Excretion

Question 20

Which of the following best explains why positive feedback is less common than negative feedback in the human body?

Accepted Answer

Positive feedback amplifies changes and can be harmful if not controlled, while negative feedback maintains stability.
