(15 cards)
what is peristalsis
-contraction of muscular tissue that helps move food through the gut
what does bile do
- emulsifies fats giving larger SA for lipase
-neutralises stomach acid for enzymes
what breaks down starch and what into
amylase to maltose
what breaks down maltose and into
maltase to glucose
what breaks down proteins and into what
protease into amino acids
what breaks down lipids and into what

where excess water is absorbed fro food
what is the function of the rectum

what is the function of the stomach
-pumels food with muscular wall
-produces protease
-hcl to kil bacteria
-optimum ph for protease (acidic)
what is the function of the pancreas
-produce protease, amylase, lipase into small intestine
what is the function of the small intestine
- produce protease, lipase, amylase
-where nutrients are absorbed out the gut into body
how is the small intestine adapted for absorption
-large SA
-vili with microvilli with blood supply for quick absorption
-very long so time for food to break down
what is the function of the mouth
–teeth break down food
- salivary glands produce amylase
