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:
