DS3: Liver to large intestine

what does the liver do?

bodys main filter: produces bile, stores glucose in glycogen, detoxifes blood, de-amiontes amino acids

what is bile?

stored in gallbladder: released into small intestine to help digest fats

why does the liver store glucose in glycogen form?

ensures all organs have a steady supply of fuel, stores it fast

how does the liver detoxify the blood?

makes enzymes that break down toxins like alcohol, nicotine, posions, excess hormones

how does the liver deaminate amino acids?

removes nitrogen, producing ammonia and urea

where does the liver get its blood?

small intestine nutrients aborbed or from oxygenated blood from lungs/heart

what does bile do?

emulsifies: breaks big fats into small fats (allows for more surface area in digestion)

why do we store bile?

eating large portions of fat is helpful but can lead to gallstones from bile salts crystalizing

what is the absorption of nutrients?

gluclose is transported into cells of intestinal walls to move into bloodstream

how are amino acids absorbed?

transported into cells of intestinal wall to move into bloodstream

what happens to glycerol and fatty acids when absorbed?

diffuced in intestinal wall: coated into proteins and moved into lymp vessels then bloodstream

what does the large intestine do?

absorbs water and electrolytes, produces feces, houses bacteria

why does the liver absorb water and electrolytes?

helps make feces (shit) solid. really solidifies that shit. and prevents dehydration

what is the appendix?

stores ‘good bacteria’ and helps us well, shit.

what are some digestive disorders?

ulcers, inflamed bowel disease, hepititis, cirrhosis, galstones

what is ulcers

thick layer of mucous in stomach gets run down- can cause holes in stomach
