Pig Dissection Relate and Review

In the Pig Dissection, we used the knowledge of External Anatomy, Digestive System, Respiratory System, Circulatory System, Endocrine System, Immune System,  and Urinary and Reproductive systems and answered how do all these systems apply to the Pig's anatomical structure. The External anatomy(the easiest to identify) included the External Ear, Eyelid, Wrist, Shoulder, Digits, Ankle, hip, tail,umbilical chord, thoracic and abdominal cavity, along with the gender of the pig which was a female. Digestive System(to eat) includes the mouth, incisor teeth, canine teeth, tongue, papillae, hard and soft palates, esophagus, stomach, liver, gall bladder, pancreas, large and small intestine, rectum and anus. The dissection for the Digestive organs is the longest because of how we need to first cut it body, break the pig's throat and mouth open. The Respiratory System(to breathe) includes the nostrils, larynx, trachea, lungs, and diaphragm. The parts were also as easy to identify. For the Endocrine System(Control hormones), it includes the cervical and thoracic thymus portions, thyroid, and spleen, which were parts very hard to identify that we could only find the pig;s thyroid and spleen. The Circulatory(transports materials throughout body) includes the heart organs (right and left auricles, and right and left ventricles, and the vessels(Coronary Artery, Aorta, Superior and Inferior vena cava, Umbilical arteries and veins, and Renal arteries and veins. The coronary artery took the most time to identify. Then the Urogenital (Excretes waste) included the kidney, ureter bladder, and since our pig was a female, an ovary, uterine horn, uterus, vagina, and genital papillae, which are used when they give birth to young pigs. My favorite part of the dissection was cutting the pig's body and being able to observe the many parts that are same shaped in humans such as the digestive organs.Pig Dissections are always very valuable since they just increase our understanding of how human body systems are also similar to the animal body systems. This whole lab relates to the last few vodcasts before the Lymphatic and Inflammatory vodcast, which included the Nervous, Endocrine,Digestive, Immune, Respiratory and Circulatory system vodcasts.
