Match the digestive organ on the left with its function.
RUDIKE [14]

Answer:

pancreas: secretes digestive enzymes into the small intestine

esophagus: the place where peristalsis takes place

small intestine: area of the digestive tract where most nuturients are absorbed

stomach: area of the digestive tract that follows the esophagus

large intestine: area of the digestive tract where mostly water is absorbed

Explanation:

peristalsis: so the food can move down towards your stomach, independently of gravity

pancreas: helps your stomach become the ultimate weapon to destroy anything that gets in there with its enzymes

small intestine: it is really really long -> more time to absorb nutrients

large intestine: like a farm of bacteria, the most exotic things that somehow made it through all the way here are finally destroyed -> also, water absorbtion: your body wants to retain as much as possible, this is how and where stool formation takes place
