Question 1

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

Accepted Answer

Specific functions are performed by specific structures, and the form of a structure relates to its function.

Question 2

A physician uses the scientific method to diagnose a patient. Which of the following steps is NOT part of the scientific method?

Accepted Answer

Making a diagnosis without gathering evidence

Question 3

Which level of organization is correctly matched with its description?

Accepted Answer

Organ level: Organs are made of two or more tissues working together to perform specific functions

Question 4

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

Accepted Answer

Regulation of blood glucose by insulin

Question 5

In the regulation of blood glucose, which organ acts as the control center?

Accepted Answer

Pancreas

Question 6

Which type of anatomy focuses on the study of cells?

Accepted Answer

Cytology

Question 7

A patient presents with a fever and tiredness. Which terms best describe these findings?

Accepted Answer

Fever is a sign; tiredness is a symptom.

Question 8

Which organ system is primarily responsible for rapid, short-term responses in extrinsic homeostatic regulation?

Accepted Answer

Nervous system

Question 9

What is the correct sequence of components in a homeostatic regulatory mechanism?

Accepted Answer

Receptor → Control center → Effector

Question 10

Which of the following best describes positive feedback?

Accepted Answer

It produces a response that amplifies the original change in conditions.

Question 11

Which organ system is NOT directly involved in the regulation of body temperature?

Accepted Answer

Urinary system

Question 12

Which of the following is a function of the lymphatic system in homeostatic regulation?

Accepted Answer

Removal, destruction, or inactivation of toxins and pathogens

Question 13

Which equation best represents the relationship between atoms and molecules at the chemical level?

Accepted Answer

$$	ext{Molecule} = 	ext{Atom}_1 + 	ext{Atom}_2$$

Question 14

A patient is unable to maintain blood pressure within normal limits. Which organ systems are most likely involved in this homeostatic failure?

Accepted Answer

Nervous and endocrine systems

Question 15

Which of the following best describes dynamic equilibrium in physiology?

Accepted Answer

Physiological systems continually adapt and adjust to changing conditions.

Question 16

Which specialty of anatomy would be most useful for a surgeon planning an operation on the heart?

Accepted Answer

Regional anatomy

Question 17

Which of the following is a correct example of autoregulation?

Accepted Answer

A blood vessel dilates in response to decreased oxygen levels in the surrounding tissue.

Question 18

Which of the following is NOT a component of the scientific method used in medical diagnosis?

Accepted Answer

Ignoring patient symptoms

Question 19

Which organ system is primarily responsible for the absorption of oxygen and elimination of carbon dioxide?

Accepted Answer

Respiratory system

Question 20

Which of the following best describes the role of effectors in a homeostatic regulatory mechanism?

Accepted Answer

They carry out the commands of the control center to restore balance.
