These tissues secrete compounds that help with digestion -- the mucosal lining in your stomach, for example, secretes stomach acid -- and also absorb the nutrients from your food.

Proteins are degraded into small peptides and amino acids before absorption. Chemical breakdown begins in the stomach and continues in the large intestine.
