Protese
an enzyme that digests or breaks down protein

Bile
produced in the liver, stored in the gall bladder
8 of 35
peristalsis
its the muscular contraction of the oesophagus that contracts and uses down food bolus

malnutrition
is when you take in too much bad food or too little of any foods so you either become anorexia because your not eating enough or obese because your eating to much bad stuff

Absorption
the absorption of digested food into the bloodstream
14 of 35
assimilation
building up of large molecules from smaller ones e.g.) glucose to glycogen

Egestion
getting rid of undigested waste material in the form of feces
16 of 35
Gullet
muscular tube, long transports food from out to stomach
17 of 35
stomach
hydrochloric acid, protease breaks down protein
18 of 35
pancrease
produces enzymes amylase and protease and lipase

rectum
stores faces for 24hrs
21 of 35
****

22 of 35
appendix
no function
23 of 35
Duodenum (small intestine)
digestion is completed their
24 of 35
lleum (small intestine)
digested food is absorbed into the blood stream through the vili
25 of 35
gall bladder
stores bile, neutralises stomach, emulsifies fat
26 of 35
liver
priduces bile,stores the products of digestion
27 of 35
bile production
bile neutrilis stomach acids, emulsifis fats
28 of 35
digestion in the small intestine
a good blood supply, a thin lining, very large surface area
29 of 35
vili
are very small finger like projections linning the small intestine there are many millions of vili in the small intestine

blood capillaries
which absorb amino acids and sugars
