The Parotid Salivary Gland is behind the mouth, above the pharynx. The Pharynx is below the salivary glands, but before the esophagus. The Esophagus is located in the center of the body, and vertically connects the pharynx to the stomach. The Stomach is on the left-side of the body, located between the esophagus and intestines. The Liver is on the right-side of the body, located over the stomach and gallbladder. The Gallbladder is also on the right-side of the body, located directly under the liver. The Pancreas is slightly off-center (more right), located under the stomach, above the transverse colon. The Transverse Colon rests horizontally in the human body, below the stomach, gallbladder, pancreas, and liver. The Descending Colon is on the left-side of the body, and the Ascending Colon is on the right-side of the body; both are on the outside of the small intestine. The Small Intestine is below the transverse colon, and between the ascending and descending colons. The Rectum is vertically centered below the descending colon, above the anal canal. The Anal Canal is also vertically centered, but it is directly below the rectum. The Appendix is on the right-side of the body, below the ascending colon.

I will remember the location of each body part by studying the picture and memorizing where they are located. It will also help to read the above paragraph while looking at the picture without the labels on it.

Part III

The Mouth is involved in propulsion, mechanical, and chemical digestion. The Small Intestine is involved in propulsion, absorption, and chemical and mechanical digestion. The Esophagus is involved only in propulsion. The Stomach is involved in propulsion, absorption, and chemical and mechanical digestion. The Large Intestine is involved in propulsion, absorption, and chemical digestion.

Part IV

Propulsion can be defined as muscular movement that pushes food through the digestive tract. Without propulsion,...
