Study Notes

Mouth

Initiates the digestive process; enzymes released help break down food.

Epiglottis

Tissue that covers the larynx, preventing food from entering the airway during swallowing.

Gallbladder

Small pouch that stores bile; releases bile into the duodenum to aid fat digestion.

Small Intestine

Longest part of the digestive system, despite being called "small" due to its width; continuous tube with the large intestine.

Duodenum

First section of the small intestine; name means "12 each," based on its believed length correlating to 12 fingers.

Jejunum

Middle section of the small intestine, approximately 5 to 8 feet long.

Ileum

Final section of the small intestine; the longest part, measuring 16 to 20 feet.

Appendix

Attached to the cecum; inflammation of the appendix is known as appendicitis.

Pharynx

A shared passageway for food and air, connecting the mouth to the esophagus and the trachea.

Esophagus

Muscular tube transporting food from the pharynx to the stomach.

Liver

Largest internal organ responsible for storing energy, detoxifying substances, and producing bile.

Stomach

Contains a tough, acidic lining to facilitate food breakdown in the digestive process.

Pancreas

Produces insulin and other hormones; generates enzymes crucial for food digestion in the intestines.

Large Intestine

Comprised of three parts: cecum, colon, and rectum; key in water absorption and waste formation.

Cecum

The beginning of the large intestine; a pouch-like structure receiving material from the small intestine.

Colon

Largest segment of the large intestine, divided into ascending, transverse, and descending sections.

Rectum

The terminal section of the large intestine, measuring 6 to 8 inches; stores stool until excretion.

Anus

The exit point of the digestive tract; expels waste (stool) from the body.
