Digestive system Flashcards
Large intestine
Water absorption
Small Intestine
3 parts
-doudenum( where chemical digestion occurs)
-jejenum( villi cover the foldings of si increasing surface area of si)
-ileum(absorb what jejenum cant like salt)
Rectum
Abosrb H2o
Epoglottis
Cover to trachea
pharynx
Throat Passage way
esophagus
Connective tissue
muscle contraction persitelsis
stomach
Produce: pepsin ( breaks down protein works in acidic environment)
Hydrochloric acid: Prevents amylase to breakdown carbs
Mucus: lubricate stomach wall protection
Both C and M digestion
Mouth
M and C
M= Teeth
C= Salivary amylase from salivary glands
Liver
Produce Bile
Pancreas
Secretes: Insulin blood sugar hormone
:amylase
:lipase
:trypsin
:sodium bicarbonate
sends to doudenum
Salivary Glands
Secretes amylase an enzyme breaking down starches or carbs
Gall bladder
Bile storage
Pyloric Sphincter
Entrance to doudenum
exit to stomach
muscles that controls food direction and allows the food to avoid going backwards
Cardiac sphincter
Avoid the bolus and stomach acid to move up back to esophagus
GERD
Sphincter is open specifically cardiac and allows acid to go up to esophagus
Treated by wrapping sphincter
Gastritis
When stomach lining dont produce enough mucus
Ulcer
hole in stomach wall
Lactose Intolerance
When theres not enough lactase to break down lactose or digest lactose
Heart Burn
Discomfort in the upper chest caused by over eating, alchohol,smoking
Macronutrient
Broken down in Chemical Digestion
provides energy for body broken down into carbs \, fats, protein
Where is chemical compounds used
Metabolism
Enzyme
a catalyst which speeds up digestion process
