You will get to know and love your preserved rat over the course of this dissection. In Biology 3A, a much more detailed look at mammalian anatomy will be conducted. Where are the Dorsal, Ventral, Medial, Lateral, Anterior and Posterior aspects 2. You may recognize and remember structures that you learned during that dissection. Arteries carry blood away from the heart. You may recall that in your first-year biology course you dissected a grass frog and a fetal pig. Use the table below to estimate the age of your pig. Determine the age of your pig by measuring the length from the tip of the snout to the attachment of the tail. The arteries and veins are challenging to identify, especially if the pig is not injected with dye. The Normal gestation (the period of time the fetus takes to develop in the uterus) for pigs is about 112 115 days. If you have a female pig look at another group’s male pig and vice versa. Make sure you can locate:įinally in the abdominal cavity are the reproductive organs. Use this guide to help you dissect a preserved fetal pig, or just look at the labeled pictures to get an idea of what the organs look like. Which digestive organs located in the abdominal cavity are considered to be accessory organs?Īlso in the abdominal cavity you will find the excretory system organs.Name one process that occurs in the large intestine.Name the three sections of the small intestines in order.What type of digestion occurs in the stomach?.

The model can be used look at the anatomy of the major body systems. As the pig is a mammal, many aspects of its structural and functional organization are identical with those of other mammals, including humans. What is the function of the gallbladder? They build the pig and then add the organs to the model. In the following laboratory exercise, you will examine in some detail the external and internal anatomy of a fetal pig (Sus scrofa).
