Question 9

Which of the following correctly matches a body cavity with a major organ it contains?

Accepted Answer

Thoracic cavity – lungs

Question 10

A patient is experiencing rapid blood loss. The body responds by increasing the rate of blood clotting. Which type of feedback mechanism is this, and what is the general formula for feedback regulation?

Accepted Answer

Positive feedback; $$\Delta x = x_{stimulus} + x_{response}$$

Question 11

Accepted Answer

Medial

Question 12

If a patient has pain in the right lower quadrant (RLQ) of the abdomen, which organ is most likely involved?

Accepted Answer

Appendix

Question 13

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

Accepted Answer

Protects the body from environmental hazards and regulates temperature

Question 14

A patient is diagnosed with diabetes mellitus, a condition in which blood glucose regulation fails. Which organ system is primarily responsible for this regulation?

Accepted Answer

Endocrine system

Question 15

Which of the following best describes the anatomical position?

Accepted Answer

Standing upright, facing forward, arms at sides, palms facing forward

Question 16

Which of the following scenarios best illustrates the use of correct anatomical terminology?

Accepted Answer

The heart is superior to the diaphragm.

Question 17

Which of the following is a correct description of a serous membrane and its function?

Accepted Answer

A double-layered membrane that reduces friction between organs in body cavities

Question 18

A patient is experiencing difficulty breathing due to fluid accumulation in the pleural cavity. Which body cavity and membrane are directly involved?

Accepted Answer

Thoracic cavity; pleura

Question 19

Which of the following best explains why positive feedback mechanisms are less common than negative feedback mechanisms in the human body?

Accepted Answer

Positive feedback mechanisms are less effective at maintaining homeostasis because they amplify changes rather than counteract them.
