Human digestive system glycoprotein called haptocorrin which is a binding protein to vitamin B. It binds with the vitamin in order to carry it safely through the acidic content of the stomach. When it reaches the duodenum, pancreatic enzymes break down the glycoprotein and free the vitamin which then binds with intrinsic factor. Food enters the mouth where the first stage in the digestive process takes place, with the action of the tongue and the secretion of saliva. The tongue is a fleshy and muscular sensory organ, and the very first sensory information is received via the taste buds in the papillae on
Methanogens in digestive tract of ruminants cellulose breakdown occupy the rumen. They initiate the fermentation process.The animal observes the fatty acids, vitamins and nutrient content on passing the partially digested food from rumen to omasum which, decreases the pH level and thus initiates the release of enzymes for further break down the food which is later passed to the abomasumthat absorbs remaining nutrients before excretion.This process takes about 9–12 hours. Some of the microbes in ruminant digestive system are: Methanogens in digestive tract of ruminants Methanogens are a group of microorganisms that can produce methane as a byproduct of their metabolism.They hold an important place in
