Question 1

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

Accepted Answer

The function of a body part depends on its structure, and the structure is designed to perform its specific function.

Question 2

Which of the following is NOT one of the four basic tissue types found in the human body?

Accepted Answer

Skeletal tissue

Question 3

A patient is unable to maintain a stable internal body temperature when exposed to cold environments. Which requirement for life is most directly compromised?

Accepted Answer

Homeostasis

Question 4

Which of the following best illustrates a negative feedback mechanism in the human body?

Accepted Answer

Regulation of blood glucose levels by insulin, where increased glucose triggers insulin release to lower glucose.

Question 5

Which of the following is a correct sequence of structural organization in the human body, from simplest to most complex?

Accepted Answer

Cell → Tissue → Organ → Organ system → Organism

Question 6

Which of the following is an example of a necessary life function that involves the breakdown of ingested foodstuffs into simple molecules?

Accepted Answer

Digestion

Question 7

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

Accepted Answer

Microscopic anatomy

Question 8

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

Accepted Answer

Determines the set point at which a variable is maintained and processes input from receptors.

Question 9

Which of the following is considered a survival need for humans, and is the most abundant chemical in the body?

Accepted Answer

Water

Question 10

A patient has a disorder in which their body cannot remove metabolic wastes efficiently. Which necessary life function is most directly affected?

Accepted Answer

Excretion

Question 11

Which of the following best describes the afferent pathway in a homeostatic control system?

Accepted Answer

It carries information from the receptor to the control center.

Question 12

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

Accepted Answer

Blood clotting after a vessel injury

Question 13

If a person is unable to separate their internal environment from the external environment, which structure is most likely compromised?

Accepted Answer

Plasma membrane

Question 14

Which of the following is NOT a requirement for human survival?

Accepted Answer

Vitamin D

Question 15

A person is exposed to a cold environment. Their body responds by shivering to generate heat. Which component of the homeostatic control system is responsible for this response?

Accepted Answer

Effector

Question 16

Which of the following best describes homeostasis?

Accepted Answer

The process by which the body maintains a relatively stable internal environment despite external changes.

Question 17

Which of the following is an example of metabolism?

Accepted Answer

The breakdown of glucose to release energy in cells

Question 18

Which of the following best describes the function of the muscular system?

Accepted Answer

Allows manipulation of the environment, locomotion, and facial expression

Question 19

Which of the following is a correct example of a homeostatic variable?

Accepted Answer

Blood sugar

Question 20

A patient is experiencing a homeostatic imbalance due to a disturbance in their internal environment. Which of the following is a likely consequence?

Accepted Answer

Increased risk of disease
