Outlines the role of the small intestine in breaking down food
Most of the digestion finishes here.In the small intestine, carbs are converted to glucose and proteins converted to amino acids.Some fats are converted to fatty acids and glycerol while most fats are emulsified by bile and absorbed without chemical

change. Any useful nutrients pass through the intestine wall into the body where blood takes them to the cells.

Discuss the difference in pH of the stomach and the small intestine
Gland of the stomach produce hydrochloric acid making it much more acidic (low pH). Pancreatic juice in the small intestine is alkaline as it neutralises the contents from the stomach.

Identify that the manner of administration of a drug may be related to its solubility
Different rates of solubility means different means of administration of the drug. For example fast acting drugs are administered by inhalers (asthma) are contained in aerosols so they can diffuse rapidly. Drugs given by skin patches or injections

are absorbed by the body at slower rates.
5 of 7
Identify vitamins that are water-soluble
B1, B2, Niacin, B6, vitamin C, pantothenic acid, biotin, B12, and folate. These substances need to be consumed daily as the body excretes them in urine rather than storing them
6 of 7
Identify vitamins that are fat-soluble
vitamins A, D, E and K. Because they are fat-soluble, they can be stored in body tissue.
