Dissection: Fetal Pig

       A dissection was done in class to physically view the anatomy of the pig and to gain a better understanding of the organs in each focused system.

Before and After 

The sex of our pig is MALE because testis were present.

Brain - Controls almost everything that happens internally

Eye - (Lens and Cornea) Vision and optic nerves to transmit images to brain

Thyroid - Regulates metabolism and produces T3 and T4

Trachea and Larynx - The trachea allows for air passage while the larynx manipulates volume and pitch 

Heart - Propels blood throughout the body

Diaphragm - Below the lungs, a thin muscle (almost like a membrane) separates the chest cavity from the abdomen and allows for the expansion of the lungs when we breathe

Liver - Located below the diaphragm, the liver produces proteins for blood plasma, and is glycogen storage

Gallbladder - On the underside of the liver, the gallbladder produces, stores, and transports the bile to the duodenum after eating

Pancreas - In the upper abdomen behind the stomach, the pancreas produces enzymes that aid the in break down of left over food in the the stomach and produces insulin to regulate blood sugar levels

Spleen - Touching the pancreas, the spleen recycles old red blood cells and stores platelets and white blood cells

Small Intestine - 90% of the digestion and absorption of food occurs

Large Intestine - Absorption of water takes place

Stomach - Chemical (acids, enzymes, pepsin) and physical breakdown of food
We actually noticed a bit of some greenish black substance inside the stomach. We believe it to be amniotic fluid.

Kidney - Filters waste products from blood and is excreted as urine
