Poor Piggy: Pig Dissection Lab

Image
In replace of a video, I decided to write about it instead of show it. External Anatomy: Usually, the fetal pig is a light beige/ off pink color. To dissect it, you must tie down the wrists on the plate to have the ventral area exposed for dissection. The wrists of the pig is cut out of the diagram, but just like humans, it would be located near the ends of the arm. The shoulder is spread openly, which can be found after the elbow of the arm. Digits are essentially the fingers and toes of a pig. They are connected to the wrist, at the end of the arm. Those two structures allow the pig to move. The thoracic cavity is everything from the diaphragm and up. We'll talk about what goes into that portion of the pig later. The abdominal cavity should be everything below the thoracic cavity. To determine the sex, you look at the urogenital opening. On males, it should be located near the umbilical cord. For females, the opening is near the anus. Digestive System: In a digestive sys...

He founded the system of binomial nomenclatures that separated themselves into eight levels of organization. This is still used today! The broadest category would be the domain which it divides into three: archaea, bacteria, and eukarya. The next level would be kingdoms. Eukarya contains of protista, fungi, plantae, and animalia. Fungi and plantae can be easily described, or easier than animalia. Animalia has over fourteen different, major groups, or phylums. There are chordates, arthropods, echinoderms, and etc. The next levels, in order, would be class, order, family, genus, and species.  Even though this unit was pretty lengthy, I wish we could have expanded on more concepts. I wish we applied the classifications in history, like how would we classify dinosaurs and other animals that can be found in the geologic timeline. This also goes with out last unit, and y...
