CSCC BIO-1101: UNIT 1 REVIEW WITH
QUESTIONS AND ANSWERS MEANT
FOR REVISION 2025 UPDATE
1. What is the study of the functions of the body systems called?
ANS: Physiology
2. What is the universal reference position of the body?
ANS: Anatomical position
3. Is the knee proximal to the thigh?
ANS: False
4. Which term would correctly describe the location of the heart in relation to the spine?
ANS: Anterior
5. The liver is a _____ organ.
ANS: Unilateral
6. The stomach resides in which cavity?
ANS: Abdominal
7. Is the brain located in the ventral, cranial cavity?
ANS: False
, 8. What fluid causes increased interstitial fluid (edema) due to injured blood vessels
(hemorrhage)?
ANS: Plasma
9. What is the fluid lost as sweat on a warm day?
ANS: Extracellular fluid
10. Even if you haven’t eaten for a while, your blood glucose levels are maintained at a
relatively stable level by homeostatic mechanisms. Is this statement true or false?
ANS: True
11. Which system(s) form the communication or "feedback" loops to maintain
homeostasis?
ANS: Both; endocrine system and nervous system
12. As we maintain homeostasis, which types of cells send information to the brain and
spinal cord about our environment?
ANS: Sensory nerve cells
13. Do most homeostatic mechanisms work by using positive feedback?
ANS: False
14. You were lying down for a while and then rise quickly, causing your blood pressure to
drop. However, you don’t faint because homeostatic mechanisms work to raise the blood
pressure. What type of feedback mechanism is this?
ANS: This is an example of a negative feedback mechanism at work.
15. If blood glucose is low, what must the body do to return to homeostasis?
ANS: Release a hormone (glucagon) which acts to raise blood glucose levels
