Includes prehension, mastication, digestion, absorption, and waste elimination.

Layers of the gastrointestinal tract that help in movement and absorption.

Glands that produce saliva, aiding in digestion and oral health.

Carnivores have sharp teeth; herbivores have flat teeth for grinding.

Mechanical is physical breakdown, chemical is enzymatic breakdown of food.

Consists of regions like the fundus, body, and pylorus, each with specific functions.

Rhythmic contraction of muscles to move food through the digestive tract.

Includes specialized structures like the crop and gizzard for food processing.

The process of swallowing, mainly controlled by the hypoglossal nerve (CN XII).

The muscle controlling the entrance of food into the esophagus from the pharynx.

Also known as the cardiac sphincter; it controls food entry from the esophagus to the stomach.

Different mammals have varying muscle types in the esophagus; skeletal muscle vs. smooth muscle.

The stomach stores, mechanically breaks down, and chemically breaks down food.

The dividing line in the equine stomach between glandular and non-glandular regions.

Depressions in the stomach lining that contain cells producing acids and enzymes.

Cells in the stomach that produce hydrochloric acid for digestion.

Cells in the stomach that produce pepsinogen, an enzyme precursor for protein digestion.

Glands located ventral to the ear canals.

Located ventral to the parotid glands near the mandible.

Located under the base of the tongue.

Glands located in the cheek, also called zygomatic in dogs and cats.

Saliva contains water, proteins, electrolytes, antibodies, glycoproteins, bicarbonate, and enzymes.

Stimulates larger volumes of watery saliva.

Stimulates smaller volumes of more mucoid saliva.

Chewed food mixed with saliva ready for swallowing.

Enzyme in saliva that digests starch; less present in dogs, cats, and ruminants.

Inactive precursor of pepsin, activated by HCl.

Enzyme that digests proteins into smaller peptides.

Hormone secreted by G cells which stimulates HCl production.

Part of the autonomic nervous system that stimulates digestion.

Release of digestive juices before food enters stomach.

Hormone that aids digestion by stimulating gallbladder contraction.

Hormone that regulates water homeostasis and stimulates bicarbonate secretion.

Muscle contractions in the stomach that aid digestion.

First part of the small intestine where most chemical digestion occurs.

An enzyme that activates trypsinogen for protein digestion.

Part of the small intestine responsible for nutrient absorption and chemical digestion.

Lymphoid tissues in the ileum that play a role in the immune system.

An artery supplying blood to the stomach, pancreas, liver, and proximal duodenum.
