Enterokinase
Activates Trypsinogen enzyme
Bicarbonate
Nutralizes chyme - Deactivates pepsin
Enterogastrone
Slows peristalsis movement
Large intestine
Absorbs water, salts, and some vitamins - stores waste until defecation
stores E. Coli - create Vitamin B, K
Cirrhosis
Damaged liver tissue gets replaced by scar tissue
Jaundice
Yellowing of the skin by bile salts produced in liver but cannot get to gall bladder becuase of gall stones
Gall stones
Bile salts and LDL form blockages in the bile duct
Liver
Detoxifies blood by filtering substances
Stores glycogen, vitamin A,B,D
Bile Salts
Emulsify fats apart
Made in liver - Stored in gall bladder
Lipase
Enzyme that digests Lipids
Made in pancreas - S.I.
Erepsin
Enzyme that digests proteins
Erepsinogen --> Erepsin
Made in pancreas - S.I.
Trypsin
Enzyme that breaks proteins down
Trypsinogen --> Trypsin
Made in pancreas - S.I.
Pancreas
Nutralize chyme from the stomach - produce enzymes
Lacteal
Small vessel inside the villi that absorbs fatty acids
Microvilli
Small formations on the villi - greatly increase surface area for absorbtion
Villi
Finger like formations on the wall of the small intestine - used to create more surface area for absorbtion
Small intestine
Chemically digest food and absorbs nutrients - transport undigested waste to the large intestine
Endoscope
A tube shaped instrament with a camera - used to diagnose problems inside the body
Histamine
Histamine is produced to try and counter the ulcer but it makes it worse
Ulcer
The protective layer of mucus breaks down exposing stomach acid to capillary network
Pepsin
Enzyme that starts protein digestion
pepsinogen --> Pepsin
Made in stomach and pancreas - S.I. - Stomach
Hydrochloric acid
Acid in the stomach - activate pepsinogen - pH (2-3)
Mucous cells
Secreate mucus so the stomach walls dont get dissolved
Sphincters
Lower esphogus gate - pyloric exit
Stomach
Stores food and starts protein digestion
Epiglotts
The gate that controls movement of food and air to their respective places
Peristalsis
The rythmic contracions of the esophagus that brings food to the stomach
Amylase enzyme
Enzyme produced in the mouth that digests carbs
Salivary gland
Produces amylase enzyme
Egestion
the removal of undigested materials
