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

Question 1

Which division of anatomy focuses on the study of large, visible structures such as muscles and bones?

Accepted Answer

Gross or macroscopic anatomy

Question 2

The principle of complementarity of structure and function states that:

Accepted Answer

Function always reflects structure, and what a structure can do depends on its specific form.

Question 3

Which level of structural organization is defined as a group of similar cells performing a common function?

Accepted Answer

Tissue level

Question 4

A patient presents with a wound that is healing slowly. Which life function is most directly impaired?

Accepted Answer

Reproduction (cellular level)

Question 5

Which of the following is an example of negative feedback in homeostatic regulation?

Accepted Answer

Regulation of blood glucose by insulin

Question 6

If the body temperature rises above 37°C, which homeostatic mechanism is activated?

Accepted Answer

Negative feedback to reduce temperature

Question 7

Which organ system is primarily responsible for removing metabolic waste products such as urea and carbon dioxide?

Accepted Answer

Excretory system

Question 8

A person is unable to sense and respond to stimuli. Which necessary life function is most affected?

Accepted Answer

Responsiveness

Question 9

Which of the following best describes the role of the receptor in a homeostatic control system?

Accepted Answer

Monitors the environment and responds to stimuli

Question 10

Which survival need is essential for the release of energy from food?

Accepted Answer

Oxygen

Question 11

A patient with heart failure is experiencing destructive positive feedback mechanisms. What does this imply about their homeostatic balance?

Accepted Answer

Negative feedback mechanisms are overwhelmed.

Question 12

Which of the following is NOT a necessary life function?

Accepted Answer

Photosynthesis

Question 13

Which equation best represents the sum of all chemical reactions in the body?

Accepted Answer

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

Question 14

Which organ system works closely with the muscular system to allow movement of body parts?

Accepted Answer

Nervous system

Question 15

A person is exposed to high altitude, resulting in decreased atmospheric pressure. Which survival need is most directly affected?

Accepted Answer

Appropriate atmospheric pressure

Question 16

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

Accepted Answer

Enhancement of labor contractions by oxytocin

Question 17

Which of the following best describes the organ system level of structural organization?

Accepted Answer

Organs that work closely together

Question 18

Which of the following is a function of proteins as a survival need?

Accepted Answer

Needed for cell building and cell chemistry

Question 19

A scientist is studying the microscopic structure of tissues. Which division of anatomy is she working in?

Accepted Answer

Histology

Question 20

Which of the following best describes the role of the effector in a homeostatic control system?

Accepted Answer
