Q: Which of the following equations best represents the sum of all chemical reactions in the body (metabolism)?

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

Question 1

Which of the following best describes the principle of complementarity of structure and function in human anatomy?

Accepted Answer

Structure always reflects function; what a structure can do depends on its specific form.

Question 2

Arrange the following levels of structural organization in the human body from simplest to most complex: tissue, molecule, organ, cell.

Accepted Answer

Molecule, cell, tissue, organ

Question 3

Which organ system is primarily responsible for removing metabolic waste such as urea from the body?

Accepted Answer

Urinary system

Question 4

A patient is lying face up on an examination table. What is the correct anatomical term for this position?

Accepted Answer

Supine position

Question 5

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

Accepted Answer

Regulation of body temperature

Question 6

Which subdivision of anatomy focuses on the study of tissues?

Accepted Answer

Histology

Question 7

A structure located toward the midline of the body is described as:

Accepted Answer

Medial

Question 8

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

Accepted Answer

Photosynthesis

Question 9

Which serous membrane directly covers the surface of the lungs?

Accepted Answer

Visceral pleura

Question 10

A patient presents with pain in the right lower quadrant of the abdominopelvic region. Which organ is most likely affected?

Accepted Answer

Appendix

Question 11

Which organ system is responsible for transporting nutrients, gases, and wastes throughout the body?

Accepted Answer

Cardiovascular system

Question 12

Which of the following best describes homeostasis?

Accepted Answer

The condition in which the body's internal environment remains relatively constant within physiological limits.

Question 13

Which feedback system amplifies the original stimulus rather than reducing it?

Accepted Answer

Positive feedback

Question 14

Which of the following is a survival need that must be maintained within a narrow range for human life?

Accepted Answer

Normal body temperature

Question 15

Which body cavity contains the heart and lungs?

Accepted Answer

Thoracic cavity

Question 16

Which anatomical plane divides the body into right and left halves?

Accepted Answer

Sagittal plane

Question 17

Which subdivision of physiology would most likely study the effects of exercise on muscle tissue?

Accepted Answer

Exercise physiology

Question 18

A multi-step scenario: A person is exposed to cold weather, causing their body temperature to drop. Which organ system initiates shivering, and what type of feedback mechanism is this?

Accepted Answer

Nervous system; negative feedback

Question 19

Which of the following correctly matches the organ system with its major function?

Accepted Answer

Digestive system: breaks down food and absorbs nutrients

Question 20
