We also identitified the sex of our fetal pig‚ and upon observation at the base of the umbilical cord we determined the sex was a male. The first part of our dissection involved reviewing the masseter muscle structure. We use a scalpel

Dissection of the Respiratory System of the Fetal Pig Inferior to the Larynx Dissection is an art. We must carefully and accurately dissect the pig so we can identify all important parts. We must use caution when carrying and cleaning sharp dissection tools. Dissection must help us to get to figure out specific parts of the organ that we need. In general‚ dissection in biology lab will help us to see of how all the systems get together in an entire organism. We will get to see how
