Introductory
Dissecting animals helps students better understand the anatomy of, in this case, a fetal pig, and helps us prepare for what University has to offer, depending on what one will study.
Purpose
The purpose of the fetal pig dissection was to understand the scientific process of dissection and gain hands-on experience of the internal and external anatomy of the fetal pig. In addition to this, the fetal pig dissection helps students better interpret the relative position and sizes of organs, as well relation between organ and organ system.

Locating major vessels of the heart
Inferior vena cava: Runs from liver and lower part of body to right side of heart. Empties into right atrium.
Superior vena cava: Runs from upper body of pig to right side of heart. Empties into right atrium.
Pulmonary trunk: Begins at right ventricles. Transports deoxygenated blood to lungs.
Aorta: Largest artery in circulatory system. Branches to transport blood to all major organs.
Aortic arch: Part of aorta that arises from left ventricle. Two major vessels come from aortic arch: Bracheocephalic trunk: Splits to send to right forelimb + head. Left subclavian artery: Supplies left forelimb.
14. Using the blunt probe, you can discover 4 chambers of heart. Locating the right chamber via the diagram below. It is visible within the eye. Locating the left atrium is also visible within the eye. You will notice several veins at left atrium, known as the pulmonary veins. Also, isolate pulmonary veins from heart via scissors. Locate the aorta coming off left ventricle and separate from heart via scissors. Then, locate pulmonary trunk arising from right ventricle and separate from heart via scissors. Finally, remove heart from thoracic cavity by teasing away connective tissue.
15. After so, make incision that separates left side and right side of heart.
16. Locating the lungs: Lungs are very visible with eyes. Lungs are relatively large due to the fact that
