Teeth = increase surface area
Tongue = tastes and pushes food
Salivary Gland = produces Saliva
Saliva contains Lysozyme, Amilase
Lysozyme = kills bacteria
Amilase = digests starch (Carbs) into Maltose (Disaccaride)
Epiglottis = blocks the respitatory track while swallowing food
Esophagus = Peristaltis, pushes food to the stomach
Stomach = produces hydrochloric acid, gastrin (hormone), pepsinogen, gastric lipase.
Hydrochloric acid = kills bacteria, activates pepsinogen
Pepsin = digests proteins into peptides fragments
Lipase = digests lipase into fatty acid and glycerol
Gastrin = helps the production of Hidrocholoric acid
Liver = produce bile.
Bile = emulsifies fat (helps digestion of fat)
Pancreas = produces bicarbonate, trypsinogen, chymotripsinogen, procarboxypeptidase, lipase, amylase.
Bicarbonate = neutralizes the acid from stomach
Trypsin = digests protein into peptides fragments, activates chymotripsinogen, procarboxypeptidase
Chymotripsin = digests protein into peptides fragments
Carboxypeptidase = digests peptides fragments into amino acids
Lipase = digests fat into fatty acid and glycerol
Nuclease = digests DNA/ RNA into nucleotides
Amylase = digests starch into maltose
Small Intestine = produces secretin, cholecystokinin (hormone). There are brush-border enzymes (disaccaridase (maltase, sucrase, lactase), aminopeptidase, enterokinase, Nucleosidase). Absorb nutrients (monosaccaride, fatty acid, glycerol, phosphate, sugar (ribonucleic or deoxyribonucleic), nitrogenous base).
Enterokinase = activates trypsinogen
Aminopeptidase = digests peptides fragments into amino acid
Nucleosidase = digests nucleotides into phosphate, sugar, nitrogenous base.
Disaccharidase = digests dissacarides into monosaccarides (maltase, laktase, sukrase)
Maltase = digest maltose into 2 glucose
Lactase = digest lactose into glucose and galactose
Sucrase = digest sucrose into glucose and fructose
Cholecystokinin = triggers liver to secrete Bile
Secretin = triggers pancreas to secrete bicarbonate
Both = stops the digestion in the stomach
Colon = absorbs water, contains gut bacteria.
Gut bacteria = digest things that our body can't digest
