Q: Which equation best represents the relationship between structure and function in anatomy and physiology?

$\text{Function} \propto \text{Structure}$

Question 1

Which statement best describes the Principle of Complementarity of Structure and Function in human anatomy?

Accepted Answer

Structure determines function, and function can also alter structure over time.

Accepted Answer

Molecule, cell, tissue, organ

Question 3

A patient has a break in the skin that exposes underlying muscle. Which directional term best describes the location of the muscle relative to the skin?

Accepted Answer

Deep

Question 4

Which organ system is primarily responsible for returning leaked fluid from blood vessels to the bloodstream and providing immunity?

Accepted Answer

Lymphatic system

Question 5

During vigorous exercise, the body increases breathing rate to supply more oxygen to cells. Which two organ systems are directly involved in this process?

Accepted Answer

Respiratory and cardiovascular systems

Question 6

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

Accepted Answer

Regulation of body temperature

Question 7

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

Accepted Answer

Question 8

Which body plane divides the body into anterior and posterior parts?

Accepted Answer

Question 9

If a surgeon makes a cut that divides the body into right and left halves, which plane is being used?

Accepted Answer
