Pancreas
Gall bladder
Stomach
Your stomach has what 3 functions?
Controls food moving into the small intestine
Breaks down protein
Destroy bacteria
Breaks down Fat
First section of the small intestine is called the

rectum
colon
caecum
jejunum

liver
gallbladder
pancreas
stomach
Saliva contains this enzyme to start the digestive process.
amylase
hydrochloric acid
sodium bicarbonate
renin

absorption
peristalsis
digestion
assimilation
where there is the most absorption of nutrients
jejunum

digestion
peristalsis
absorption
assimilation
finger-like projections in the small intestine that absorb nutrients
villi
microvilli
lacteal
Villi are shaped the way they are so that:
they move food through the digestive tract
they increase the surface area of the small intestine for absorption of nutrients
they break food into smaller pieces
Lipase is made in the
mouth and esophagus
small intestines and pancreas
small intestines and large intestines
liver
What is the role of bile?
Emulsify lipids and neutralise stomach acid
Acidify the gastric juices and digest protein
Absorption and Assimilation
The protective substance that lines the stomach is called
Trypsin
Saliva
Pepsin
Mucus
Which of the following are the structural adaptations of villi for absorption?
The small intestine is very long that more time is provided for absorption of digested food.
The epithelial cell is one cell thick to shorten the diffusion distance of digested food.
Microvilli are present on cell surfaces of epithelial cells to further increase surface area for absorption of digested food.
The epithelium is one cell thick to shorten the diffusion distance of digested food.
