Accepted Answer

Supine

Question 8

Which of the following best describes the function of serous fluid within body cavities?

Accepted Answer

Question 9

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

Kidney

Question 11

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

Accepted Answer

It receives and processes information and sends out commands.

Question 12

Which of the following directional terms correctly describes the relationship between the nose and the ears?

Accepted Answer

The nose is medial to the ears.

Question 13

Which organ system is primarily responsible for long-term regulation of homeostasis through chemical messengers?

Accepted Answer

Endocrine system

Question 14

Accepted Answer

Histology

Question 15

Which of the following is an example of extrinsic regulation of homeostasis?

Accepted Answer

The nervous system increasing heart rate during stress

Question 16

Which of the following best describes the anatomical position?

Accepted Answer

Question 18

Which of the following is a real-life example of positive feedback in the human body?

Accepted Answer

Amplification of blood clotting after vessel injury

Question 19

Which of the following best explains why failure to maintain homeostasis can lead to disease?
