I am a form of mechanical digestion that changes semi digested bolus into chyme:

Gastric mixing

I am released from parietal cells and activate pepsinogen to pepsin in the stomach:

HCl (Hydrochloric Acid)

I am the terminal region of the small intestine and connect the large intestine at the cecum:

Ileum

I am the digestive enzyme released in the pancreatic juices that aids in the digestion of proteins:

Inactive proteases

I am the actual act of ingesting food:

Ingestion

Salivary amylase

Initiates the chemical breakdown of carbohydrates

I am the middle region of the small intestine:

Jejunum

I am the organ whose primary function is the absorption of water and electrolytes:

Large intestine

I produce bile:

Liver

I am the three accessory organs that send secretions to the duodenum of the small intestine:

Liver, pancreas, gallbladder

I am the duct that carries the pancreatic juices into the duodenum of the small intestine:

Main pancreatic duct

I am another term for chewing:

Mastication

I am the process when ingested material is physically broken down into smaller units by chewing:

Mastication

We are formed as a result of emulsification:

Micelles

I am small extension of the plasma membrane that form a brush border, which releases enzyme that complete chemical digestion in the small intestine:

Microvilli

We are microscopic extensions of the plasma membrane lining the wall of the small intestine to help increase the surface area:

Microvilli

We are the three forms of carbohydrates:

Monosaccharides, disaccharides, polysaccharides

I am the general term to describe the voluntary and involuntary muscular contractions for mixing and moving material through the GI tract:

Motility

I am the process that involves a series of voluntary and involuntary contractions to help facilitate the digestive process and moving and mixing things through the GI tract:

Motility

I am the reason why lipid molecules need to be emulsified:

Not water-soluble

I am the location where carbohydrate digestion begins:

Oral cavity

I am the location where mechanical digestion begins:

Oral cavity

I am the structures that make up the upper GI tract:

Oral cavity, pharynx, esophagus, stomach, duodenum of small intestine

I am the accessory organ that lies posterior to the stomach and has a tail, head, and body:

Pancreas

I am the digestive enzyme released in the pancreatic juices that aids in the digestion of carbohydrates:

Pancreatic amylase

I resume the chemical digestion of carbohydrates in the small intestine by mixing with chyme:

Pancreatic amylase

I am the digestive enzyme released in the pancreatic juices that aids in the digestion of triglycerides:

Pancreatic lipase

I am the enzyme who functions with micelles to digest each triglyceride to monoglyceride and two free fatty acids:

Pancreatic lipase

I am the largest salivary gland and am located anterior and inferior to the ear:

Parotid salivary gland

I am released from chief cells and in the stomach and hydrolyze the peptide bonds in certain amino acids:

Pepsin

We are brush border enzymes that help break the remaining chains into individual amino acids, which are then absorbed into the bloodstream:
