We must carefully and accurately dissect the pig so we can identify all important parts. We must use caution when carrying and cleaning sharp dissection tools. Dissection must help us to get to figure out specific parts of the organ that we need.

In general, dissection in biology lab will help us to see of how all the systems get together in an entire organism. We will get to see how they are all arranged spatially. Here are my twelve instructions for a fetal pig dissection.

Retrieve a fetal pig In this first method, the great caution is recommended. It is required to retrieve a fetal pig from the bucket with large tongs, being careful to drain as much preservative as possible. Stabilize the pig Place the pig ventral side up on a medium-sized dissection tray.

Secure the pig to the tray using twine. Wrap the twine behind the dissection tray and secure the second hoof.

Do the same for the back hooves. In other words, place the pig on its back and tie it with its arms and legs stretched apart using twine. Start of the dissection Beginning immediately superior to the umbilical cord, use large dissection scissors to make a small, V-shaped incision into the body cavity.

Using the blunt side of the scissors, extend this incision in a U shape inferiorly around the umbilical cord to the pelvis and superiorly through the right side of the sternum to the clavicle. We can also say make a cut in the wall of the abdomen just above the umbilical cord. Extend this cut downwards in a U shape around the umbilical cord toward each hind leg and upwards through the rib cage to the collar bone.

Lateral incision To fully open the body cavity, make perpendicular incisions laterally just superior to the hind legs, just inferior to the front legs and just inferiorly to the rib cage, between the diaphragm and the liver.

Peel back the walls of the abdomen to reveal the abdominal cavity. In other words cut perpendicularly to the mid-line incision just above the hind legs, just below the front legs and just below the rib cage.

Caution to not damage the diaphragm In order to avoid damaging the diaphragm when opening the thoracic cavity, cut the diaphragm away from the rib cage so that it lies over the liver. Gently, but firmly use both hands to crack open the rib cage.

Expose the larynx and trachea Using tweezers and a scalpel, carefully cut away the muscles of the neck to expose the larynx and trachea.Physiology of Gas Exchange.

Study Exercise Anatomy of the Respiratory System flashcards taken from the book Human Anatomy & Physiology Laboratory Manual.

Anatomy of the Respiratory System Nose and Nasal Cavity. The nose and nasal cavity form the main external opening for the respiratory system and are the first section of the body’s airway—the respiratory tract through which air moves. The nose is a structure of the face made of cartilage, bone, muscle, and skin that supports and protects the anterior portion of the nasal cavity.

In humans and other mammals, the anatomy of a typical respiratory system is the respiratory tract. The tract is divided into an upper and a lower respiratory tract. The upper tract includes the nose, nasal cavities, sinuses, pharynx and the part of the larynx above the vocal folds. Start studying A&P II - Review Sheet 36 - Anatomy of the Respiratory System.
