| Epiglottis | a cartilage flap at the base of the tongue that prevents food/liquid from entering the windpipe (trachea) by covering the larynx during swallowing. |
| Esophagus | muscular tube that transports food and liquids from the pharynx to the stomach, located behind the trachea and heart and passing through the diaphragm |
| Stomach | a J-shaped muscular organ in the upper abdomen that acts as a temporary food storage and digestive unit, churning food into chyme using acid and enzymes |
| Small Intestine | coiled, tube-like organ located in the central abdomen, connecting the stomach to the large intestineDuodenum |
| Duodenum | the first, shortest, and widest section of the small intestine |
| Jejunum | the middle section of the small intestine, located between the duodenum and ileum |
| Ileum | the final, longest section of the small intestine, located in the lower abdominal and pelvic cavity, connecting the jejunum to the large intestine |
| Cecum | a blind, pouch-like, intraperitoneal structure located in the right iliac fossa that acts as the first part of the large intestine, connecting the ileum to the ascending colon |
| Large Intestine | the final section of the gastrointestinal tract, roughly 5 feet long, responsible for absorbing water, electrolytes, and some vitamins from indigestible food residue, converting it into feces |
| Ascending Colon | the first, 12–20 cm segment of the large intestine on the right side of the abdomen, stretching from the cecum to the hepatic flexure |
| ransverse Colon | the longest, most movable part of the large intestine, spanning the upper abdomen to absorb water, nutrients, and electrolytes while forming stool. |
| Descending Colon | the left-side segment of the large intestine, extending from the splenic flexure to the sigmoid colon, that stores feces and absorbs remaining water and electrolytesSigmoid Colon |
| Sigmoid Colon | the S-shaped final section of the large intestine, located in the lower-left abdomen, connecting the descending colon to the rectum |
| Rectum | the final 10–14 cm (approx. 5 inches) of the large intestine, located in the posterior pelvis between the sigmoid colon and anal canal |
| Anus | the 3-4 cm long, terminal opening of the digestive tract located between the buttocks, connecting the rectum to the outside of the body |
