Unit 5: Absorption and Excretion
Unit 5 Objectives (Chapters 15-17)
This unit will be split into two tests: Chapters 15 and 16, and Chapter 17 (take home)
**Reminder: All of these objectives need to be answered thoroughly and be typewritten. They
will be collected along with your reflection on the day of the test. Objectives in BOLD need not
be included with this packet. Everything on the test will be based on these objectives.

19. What accessory organs (there are three!) assist the small intestine, what do each of them
secrete into the small intestine, and what functions do the secretions have? (Ch 15)
