Digestion and Absorption
Digestion
Breaking down food to molecules small enough to be absorbed into blood
salivary amylase
Enzyme in saliva that breaks down starch
pancreatic lipase
Secreted by the pancreas into the small intestine, enzyme that digests triglycerides (fats)
diarrhea
any change in bowel habits involving increased stool frequency or fluidity
The side that faces the digestive tract lumen is called _____
apical membrane
The sides faces the blood vessels is called the _______
basolateral membrane
Carbohydrates
break down into manosaccriades, lipids break down into fatty acids and monoglycerides and proteins break into amino acids
chemical digestion
breaking of covalent chemical bonds in organic molecules by digestive enzymes
mechanical digestion
breaks large food particles into smaller ones
lacteals
connected by lymphatic vessels to the thoracic duct
Carbohydrates
consist primary of polysaccharide
Triglycerides
consists of three fatty acids bound to glycerol
the final step in carbohydrate digestion is performed by series of ______
disaccharides
Lipase
enzymes digest lipid molecules
The major monosaccharides is called
glucose
Na+/K+ pump
located on the basolateral membrane
Absorption
means by which molecules moved out of the digestive tract into blood for distribution throughout the body
salivary amylase
minor amount of carbohydrates digestion begins in the oral cavity with partial digestion of starches by ________
Lipids
molecules that are insoluble or only slightly soluble in water
Triglycerides
most common type of lipid abs are often referred to as fats.
pancreatic lipase
responsible for the majority of carbohydrates digestion
lingual lipase
secreted oral cavity and swallowed food
loss of reflexes below the level of injury
spinal shock
