Unit 4 Report Distributing Metabolites through the body Food that we consume is composed of very complex molecules. During the digestive process these compounds are broken down into smaller and smaller subunits in preparation for use by the body as building blocks needed for the many components of the human body. In Module 3 we followed the food through the digestive system and considered the process that takes place in the digestive system. The pizza that was eaten by Matt and Maria contained ingredients

Classical Conditioning was created from his research on the studying of dogs salivating‚ to be more precise the secretion of digestive enzymes. In Ryazan‚ Russia Ivan Pavlov was born on September 14th 1849. He was from a large family and his father
