The Digestive System
The role of the digestive system is to break down and assimilate the nutrients from the food we eat and redistribute those nutrients to all tissues in the body via the blood circulation or the lymphatic system, so our cells can receive the required energy to function.
The digestive system requires nutrients to function: for tissue function or the release of digestive juices and enzymes. A steady supply of protein (amino acids) is, therefore, required. The intrinsic factor, which is essential to the assimilation of vitamin B12, is a protein (glycoprotein).
Histamine is also required to produce hydrochloric acid. Hydrochloric acid (and other gastric juices. e.g., potassium chloride and sodium chloride) aid digestion by creating the optimal pH for pepsin and gastric lipase, which helps your body to break down, digest, and absorb nutrients, including protein and large fatty molecules. It also eliminates bacteria and viruses in the stomach, protecting your body from infection. (1) (2)
