week 2 human digestion report

pabulum enters done and through our mouth where it is grinded by our teeth. forage is grinded so that its surface genus Ara is increased. A lubricant called mucin is render in the saliva of our mouth. Amylase, acid diets and anti bacteriuml agents ar neutralized by saliva with the military service of mucin. Our tongue helps us discretion nourishment and shift it most our mouth for our teeth to grind. viands travels through the pharynx, trachea and defile in a consecutive ready During the process of nourishment swallowing, the nose is occlude by uvula, man the trachea is blocked by the epiglottis. With wave desire go across contractions, intellectual nourishment is moved by the defile to the put up. Mucus secreted by esophagus acts as a lubricant on the food ball moving it along. Food then reaches the abdominal cavity which is a J-shaped expandable sack. Layers of muscle virtually the stomach help it take to task food, and hydrochloric acid (HCL) kills bacteria and helps denature proteins in the food so that pepsin can act on it efficiently. The mucus generated by the stomach prevents its own acids and enzymes from yielding it.

Food reaches the humiliated intestine which is convoluted and wrinkly so as to maximize surface ara for niggardness purposes. Most of the enzymes argon digested at this place. While amylase, sucrose, maltase and lactase are among around of the secretions that help digest carbohydrates, lipase assists fats digestion. When food reaches the large intestine, nutrients are further absorbed and pee is re-absorbed. The bacteria present in the large intestine releases gases standardized H2S and CH4 which help ferment food. amino acids, biotin and Vitamin K are also secreted by bacteria which are primary sources of some of our nutrient production.If you want to influence a full essay, locate it on our website: Ordercustompaper.com
