Accepted Answer

Integumentary system

Question 4

A patient presents with difficulty in locomotion and maintaining posture. Which organ system is most likely affected?

Accepted Answer

Muscular system

Question 5

Which of the following is a correct example of negative feedback in homeostasis?

Accepted Answer

Body temperature regulation by sweating when overheated.

Question 6

What is the main function of the lymphatic system?

Accepted Answer

Picks up fluid leaked from blood vessels and returns it to blood; houses white blood cells for immunity

Question 7

Which of the following best describes the role of serous membranes in body cavities?
