Food reaches the picayune intestine which is convoluted and wrinkly so as to maximize surface argona for denseness purposes. Most of the enzymes are digested at this place. While amylase, sucrose, maltase and lactase are among approximately of the secretions that help digest carbohydrates, lipase assists fats digestion. When food reaches the large intestine, nutrients are further absorbed and weewee is re-absorbed. The bacteria present in the large intestine releases gases like H2S and CH4 which help ferment food. amino acids, biotin and Vitamin K are also secreted by bacte ria which are primary sources of some of our! nutrient production.If you want to turn a full essay, devote it on our website:
