The value to students of dissecting a mammal, especially a pig because most students like to learn hands on giving them an opportunity to dissect a pig gives us a chance to give us a visual and help us understand the systems in a mammal. 2.
My feeling about dissecting a pig is nervous because it is a real pig even though it is fetal. I feel like I will end up cutting the pig in the wrong spot.

MATERIALS AND PROCDURES:
Refer to Grade 11 Biology textbook, page 640 - 645
Length of the pig: 32.5 cm
Name of the pig: Oinky
Sex of the pig: Female
Gestational age of the pig: 140 days

Tongue: It’s supplied with a number of muscular valves. That control and direct the amounts of food through the Digestive tract. Epiglottis: The Epiglottis is a flap of skin that makes sure no food gets into the Respiratory tract.
