The Digestive System
In this lab you will identify all of the major components of the fetal pig digestive system. Before you begin, recall the following information regarding dissections:
- Only use your scalpel or scissors when absolutely necessary. Clean your specimen by removing matertial with the tweezers or probes, not by cutting.
- Never walk around the lab with a dissecting instrument in your hand. Leave them at your lab station.
- Never dump waste tissue in the sink. All waste material goes in the garbage can.
