Question 5

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

Accepted Answer

Question 6

During a marathon, a runner's body temperature rises. Which organ system is primarily responsible for returning the body temperature to normal?

Question 8

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

Prone

Question 9

Which of the following statements about serous membranes is correct?

Accepted Answer

The visceral serosa covers the surface of internal organs, while the parietal serosa lines the cavity wall.

Question 10

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

Accepted Answer

It processes the signal from the receptor and sends instructions to the effector.

Question 11

A patient is experiencing rapid blood loss from a severe wound. Which type of feedback loop is activated to restore homeostasis, and what is the physiological response?

Accepted Answer

Transverse plane

Question 16

Which of the following scenarios best exemplifies the concept of dynamic equilibrium in homeostasis?

Accepted Answer
