BIOS 256 Week 1 Lab Worksheet

The BIOS 256 Week 1 Lab Worksheet focuses on understanding the digestive system structure and function, guiding students through various lab activities and assessments. The first part of the lab involves reviewing knowledge related to the gastrointestinal tract’s anatomy, digestive organ structures, and accessory digestive organs. Students will need to work through Lab Activities 1-9 (pages 561-582), ensuring they complete each section accurately and save the document as instructed for submission.

Part 1: Reviewing Your Knowledge
