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
