digestive tract
These parts of the digestive tract in the different mammals differ in the extent of their development, depending on the mode of life and the character of nutrition. Since vegetable food, differing greatly in chemical composition from the body of animals, needs to be treated more vigorously, the intestine of herbivores is very long and the large intestine is especially developed; in some animals, e.g. in the horse, the large intestine acquires accessory blind processes, in which the undigested food remnants undergo fermentation like in a fermenting vat. icd 10 training trains all these for the coding and billing and payment
