Question

Sequence the following steps for nutrient digestion.
1. Gastric secretions mix with the food material.
2. Undigested material and some liquids move to the large intestine and waste material is excreted as feces.
3. End products of digestion are absorbed through the intestinal wall and into circulation.
4. Salivary amylase breaks down food into smaller components.
5. Secretions from the gallbladder, pancreas, and intestinal lining cells digest carbohydrates, protein, and fats.
6. Salivary amylase action stops while pepsin begins to break down proteins.

	A.	5, 6, 2, 1, 3, 4
	B.	3, 4, 5, 2, 1, 6
	C.	1, 2, 3, 4, 5, 6
	D.	4, 1, 6, 5, 3, 2

Answer 1

Answer is D

4,1,6,5,3,2

Salivary amylase breaks down food into smaller components this enzymes are found in saliva in our mouth

Then food goes to stomach through oesophagus and

Gastric secretions mix with the food material

Then gall bladder, pancreatic and intestinal enzymes act on it

Then it goes to small intestine where nutrients absorbed into blood

And then undigested goes to large intestine

And then excrete as faeces
