nasal passages
15 multiple answer 2 points
choose two things the liver does
produces bile to help digest fatty foods
filters blood coming from the digestive tract
produces water to help food slide through the intestine
produces sugar to help break down food
16 multiple choice 1 point
the function of the gall bladder is to
give you strength
make gall stones
produce gas
store bile produced by the liver

Explanation:

For the first question, digestion starts in the mouth with saliva (saliva contains enzymes like amylase that begin breaking down carbohydrates). The tongue helps in moving food around but is not the start of digestion in terms of chemical breakdown. The stomach is part of the digestive process but not the first place. Nasal passages are for respiration, not digestion.
For the second question (number 15), the liver produces bile to help digest fatty foods (emulsifies fats) and filters blood coming from the digestive tract (removes toxins, processes nutrients). It does not produce water for food sliding (that's more related to intestinal secretions) or produce sugar to break down food (it stores and releases glycogen but not in that context).
For the third question (number 16), the gall bladder stores bile produced by the liver. It does not give strength (muscles etc. relate to that), make gall stones (that's a pathological condition, not its function), or produce gas (digestive processes in intestines relate to gas production).

Answer:

First question: mouth with saliva.
15: produces bile to help digest fatty foods, filters blood coming from the digestive tract.
16: Store bile produced by the liver.
