Question 1

Which of the following best illustrates the principle of complementarity of structure and function?

Accepted Answer

Question 2

A patient is unable to maintain a stable internal body temperature when exposed to cold environments. Which necessary life function is most directly impaired?

Accepted Answer

Homeostasis

Question 3

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

Accepted Answer

Regulation of blood glucose by insulin after a meal

Question 4

A midsagittal plane divides the body into:

Accepted Answer

Equal right and left halves

Question 5

Which of the following best describes the function of serous fluid found between the parietal and visceral serosa?

Accepted Answer

It lubricates the organs, reducing friction during movement.

Question 6

A patient with a severe injury to the pelvic cavity is at increased risk for damage to which organ?

Accepted Answer

Urinary bladder

Question 7

Which of the following is NOT a necessary life function?

Accepted Answer

Photosynthesis

Question 8

A person is experiencing rapid breathing and increased heart rate after running. Which two necessary life functions are most directly involved in this response?

Accepted Answer

Movement and responsiveness

Question 9

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

Accepted Answer

It determines the set point and processes information from the receptor.

Question 10

A patient is found to have a deficiency in water intake. Which of the following is a likely consequence at the cellular level?

Accepted Answer

Impaired chemical reactions due to lack of solvent for metabolic processes

Question 11

Which of the following best explains why the body cannot survive more than a few minutes without oxygen?

Accepted Answer

Oxygen is essential for the release of energy from food via cellular respiration.

Question 12

A patient is diagnosed with pleurisy, an inflammation of the serous membrane surrounding the lungs. Which specific serous membrane is affected?

Accepted Answer

Pleura

Question 13

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

Accepted Answer

Enhancement of labor contractions by oxytocin

Question 14

If a transverse (horizontal) plane is used to cut the body, which of the following results?

Accepted Answer

The body is divided into superior and inferior parts.

Question 15

A patient is experiencing a homeostatic imbalance due to aging. Which of the following is a likely consequence?

Accepted Answer

Control systems become less efficient, increasing risk of illness

Question 16

Which of the following best describes the anatomical position?

Accepted Answer

Body erect, feet slightly apart, arms at sides, and palms facing forward

Question 17

A patient is found to have a metabolic disorder affecting the sum of all chemical reactions in their body cells. Which term best describes this process?

Accepted Answer

Metabolism

Question 18

Which of the following is a function of the plasma membrane in maintaining boundaries?

Accepted Answer

It separates the internal environment of the cell from the external environment.

Question 19

A patient is unable to sense and respond to changes in their environment, such as touching a hot surface. Which necessary life function is most directly impaired?

Accepted Answer

Responsiveness

Question 20

Which of the following best describes the relationship between organ systems and survival needs?

Accepted Answer

Organ systems are designed to service the needs of cells, and all cells depend on organ systems to meet their survival needs.
