HUMAN NUTRITION

Detailed explanation-1: -As such, enzymes such as alpha-amylase secreted by salivary glands in the oral cavity and also by the pancreas cannot function in the stomach, and thus digestion of carbohydrates does not occur in the stomach.

Detailed explanation-2: -The only dietary components that are not digested in the stomach are fats and carbohydrates.

Detailed explanation-3: -All sugars and other carbs need to be broken down into easily-used monosaccharides. After you swallow, sugar and other foods travel down the esophagus via peristalsis into the stomach and then the small intestines. Here, sugars are all broken down by additional enzymes into single units and absorbed for further use.

Detailed explanation-4: -The spleen is not part of the digestive system, however, is connected to the blood vessels of both the stomach and the pancreas.

Detailed explanation-5: -During digestion, starches and sugars are broken down both mechanically (e.g. through chewing) and chemically (e.g. by enzymes) into the single units glucose, fructose, and/or galactose, which are absorbed into the blood stream and transported for use as energy throughout the body.
