It is a diffuse gland found in the mesentery between the stomach and the small intestine. What does bile do? Where does it do its job? It is embedded in the liver on the underside of the right lobe. Give an example of a protein, carbohydrate and a fat that the pig could get in his slop. What are the monomers that make up proteins, carbohydrates and fats?Ī pig can eat all of the major organic molecules that you can in his pig slop. What membrane holds the small intestines in place? What is the major function of the small intestines? Certain white blood cells (T Lymphocytes) mature in the thymus. Cut through the muscle to expose the thymus gland. The thymus gland is part of the immune system.

PIG DISSECTION DIAGRAMS SKIN

You may have to make lateral incisions to pullthe skin back. Move the skin a part in the neck region to expose the neck region. Locate and observe the thymus gland, larynx, trachea, esophagus and thyroid gland. Observation of the Neck Region of the Fetal Pig What are the major organ systems located in the abdominal cavity? (2) What are the major organ systems that are located in the Thoracic cavity?(2) What organs are located in the abdominal cavity? What two cavities does the diaphragm separate? Make lateral cuts and pull back the flaps to expose the abdominal cavity. Make a flap by cuttingaround the umbilical cord. What organs arelocated in the thoracic cavity?Ĭut posteriorly from the diaphragm to theumbilical cord. Pull back the flaps formed by these cuts to reveal the thoracic cavity. The diaphragm is the structure that separates the thoracic cavity from the abdominal cavity.Ĭut from the diaphragm up to the hairs in the throat region, then make the lateral cuts. The nasopharyngeal opening leads from the oral cavity to the nasal passages.įollowing the numbered incisions use scissors to expose the thoracic and abdominal cavities. The nasopharngeal opening is posterior to the soft palate. Notice that the esophagus is underneath the trachea.

Note that theglottis is located very close to the esophagus.Įxplain the relationship between the esophagus, the epiglottis and the glottis. The opening to the esophagus is located posterior and dorsal to the glottis. The glottis is the opening between the oral cavity and the trachea. The epiglottis is the flapthat covers the glottis. You will see a flap pointed dorsally this is theepiglottis. Push down on the tongue to open the jaws. The pharynx is a passageway for what two substances? The Pharynx is dorsal to the oral cavity and has three openings: the glottis, the esophagus and the trachea. Observation of the Pharynx of the Fetal Pig In humans what structure hangs from the soft palate? V Soft Palate - smooth region posteriorto the hard palate.
