• intestinal juice : this fluid secreted by the small intestine in response to secretin and cck, contains additional enzymes for use in the small intestine.
• peristalsis : this physical digestion action of the intestinal walls thoroughly mixes food and juices together.
• emulsification : this physical digestion action occurs in the small intestine and increases the surface area of lipids.
• disaccharide : maltose, sucrose and lactose are examples of this.
• peptidases : these enzymes from intestinal juice help digest peptides into amino acid monomers.
• maltase : this enzyme from intestinal juice helps digest maltose into two glucose monosaccharides.
• sucrase : this enzyme from intestinal juice helps digest sucrose into one glucose monomer and one fructose monomer.
• lactase : this enzyme from intestinal juice helps digest lactose into one glucose monomer and one galactose monomer.
• duodenum : this first segment of the small intestine is from the pyloric sphincter to the beginning of the jejunum and is about 25 cm long.

• ileum : this final segment of the small intestine is from the end of the jejunum to the ileocecal sphincter and is about 3.6 m long.
• absorption : this is a large job of the small intestine and involves the final products of digestion.
• villi : these are long, finger-like folds that project into the small intestine and greatly increase its surface area for nutrient absorption.
• microvilli : the villi have these minute cytoplasmic extensions.
• lacteal : this absorptive end of the lymphatic system found in each villus absorbs chylomicrons and fat-soluble vitamins.
• capillary bed : this is found in each villus and absorbs amino acids, monosaccharides, minerals, short-chain fatty acids and glycerol, water soluble vitamins, and nucleotide components.
• ileocecal : this sphincter is found between the ileum and the colon.
• cellulose : this indigestible material passes from the small intestine into the large intestine.
• water : the re-absorptio of this occurs in the colon.
• e.coli : the decay action of this bacteria on undigested food changes it into the final fecal form, while also producing the vitamins b and k.
• rectum : this temporarily stores feces until defecation.
• anal sphincter : at the end of the rectum, this controls defecation through the anus.
