Subjects : mcat, science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

13. Removes body wastes from bloodstream; helps regulate homeostasis of internal environment






14. Contractile in nature and functions to move the skeletal system and body viscera.






15. Dilates blood vessels and increases the permeability of capillaries - thus increasing interstitial fluid.
