Digestive System Senen Velasco P6
major function fo the digestive system
Digestion
mechaical
physcial breaking of large food piece into smaller pieces
Mastication
chewing
segmentation
mixing/churning
peristalsis
wave/rippling
chemical
breaks food into simpler chemical that can be absorbed by cells in the body
Absoprtion
chemically digested food moves from intestine into blood and lymph
Digestive Enzyme
protein
protein-->peptide-->aminoacids
pepsin-protein-->peptide
protease-peptide-->amino acid
carbohydrates
polysaccharides-->disaccharides and monosaccharides
amylase-poly-->di
Dissacharides-->monosaccahrides
maltase-->glucose
lactase-->glucose and galactose
sucrase-->glucose and fructose
DNA/RNA
nucleic acid--> nucleotides
nuclease-->nucleotides
Lipids
fats-->fatty acids
lipase-->fatty acids and glycerol
Location of Digestion and Absorption of each macromolecule
small intestine
duodenum
chemical digestion
liver-->bile-->fat
pancreas-->pancreatic juices
carbs protien and fats
jejunum
apsorption
cicrcular folds to increase and surface area
Layer of GI tract
mucosa
produces mucus for redutcion of friction and protection
submucosa
areolar connective tissue containing major blood cells
muscularis
muscle layer
serosa
outer covering of GI tract
Disorder of Digestive System
jaundice
when the skin turns yellow due to excessive amount of bile in the blood
gall stone
these block the bile duct
hepatitis
it is the inflamation of the liver
occurs from shared needle or sex drugs or mushroom poisining
cirrhosis
its a chronic inflamation of the liver
Major organs of digestive system
two groups
alimentary canal
mouth
pharyx
esophagus
stomach
small intetsine
large intestine
accesory organs
teeth
tongue
salivary glands
liver
gall bladder
pancreas
