The space in the mouth that aids in digestion and taste.

Includes taste, grinding of food, lubrication, and limited digestion.

Connects oral cavity to the esophagus; passage for food, liquid, and air.

The innermost layer of the digestive tract, consisting of epithelium, lamina propria, and muscularis mucosae.

Layer of connective tissue containing blood vessels and nerves beneath the mucosa.

Layer that enables movement in the digestive tract, composed of circular and longitudinal muscles.

Outermost layer of the gut in the peritoneal cavity, made of simple squamous epithelium.

Outermost layer of parts of the digestive tract not covered by peritoneum.

A muscular tube connecting the pharynx to the stomach.

Muscle at the junction of the esophagus and stomach controlling food entry.

The stomach has four layers: mucosa, submucosa, muscularis externa, and serosa.

Stomach's muscularis externa has three layers: oblique, circular, and longitudinal.

Folds in the inner surface of the stomach that allow for expansion.

Mechanically mixes food into chyme; starts protein digestion and absorbs some substances.

Muscle controlling the opening between the stomach and duodenum.

Blood supply comes directly from the celiac trunk and common hepatic artery.

Lymphoid tissue in the ileum that monitors intestinal bacteria.

A fold of tissue that attaches the intestines to the abdominal wall, containing blood vessels.

Straight blood vessels arising from the mesenteric arcades.

Includes caecum, colon segments, rectum, with key functions in water absorption and feces formation.

Pouches formed by contraction of the large intestine, allowing for segmentation of contents.

Three longitudinal muscle bands in the large intestine that create haustrations.

Similar to colon but lacks taenia coli and has longitudinal muscle; covered by peritoneum.

Foregut, midgut, hindgut supply organs with arteries: celiac trunk, superior and inferior mesenteric.

Right and left gastric arteries supply blood to the lesser curvature of the stomach.

Right and left gastro-omental arteries supply blood to the greater curvature of the stomach.

The small intestine is about 6.7 meters long; it's the longest part of the GIT.

Small intestine is divided into duodenum, jejunum, and ileum.

Villi increase the surface area for nutrient absorption in the small intestine.
