DIGESTIVE SYSTEM

• refers to the process in which animals take in food that provides energy and nutrients

  ingestion
• refers to the process in which digested foods are distributed into different parts of the body cells

  assimilation
• process of turning food into smaller molecules with the aid of ENZYMES

  chemical digestion
• where does the final stage in digestion of food happens

  large intestine
• refers to the act of chewing food. It is the initial stage of digestion

  mastication
• enzyme in saliva that helps break down starch. It is also referred to as ptyalin

  amylase
• organ system responsible for breaking down large molecules and absorbing organic compounds

  digestive system
• it is the digestive organ responsible for reabsorbing water. It is where the final part of digestion occurs

  large intestine
• refers to the contraction of smooth muscles that assists the movement of food down the esophagus

  peristalsis
• it is a thick, semifluid mass of partially digested food that is formed in the stomach

  chyme
• it is responsible for absorbing nutrients from the intestinal tract

  intestinal villi
• it refers to the process in which digested nutrients pass into the blood vessels

  diffusion
• it is the process where undigested food is released from the body in the form of feces

  egestion
• it is the correct sequence of processes involved in human digestive system

  ingestion, digestion, absorption, assimilation, egestion
• it refers to the moist ball of food that is chewed mixed with saliva

  bolus
• it is the enzyme present in the stomach that digests protein

  pepsin
• it is where digestion starts

  mouth
• it is the process of physically breaking down food with the help of teeth

  mechanical digestion
• it refers to the tube that attaches the mouth to the stomach

  esophagus
• it is a J-shaped, bag-like muscular organ that stores food

  stomach
• it produces an enzyme that helps digest fat

  liver
• it is the enzyme that digests fat

  bile
• this is where bile is stored

  gall bladder
• organ that produces insulin and other digestive enzymes i.e., amylase, peptidase, and lipase which help digest carbs, proteins, and lipids

  pancreas
• it is the organ where most of the digestion and absorption occurs

  small intestine
• what are the 3 parts of the small intestine in order

  duodenum, jejunum, ileum
• carbohydrates are broken down into sugars/glucose

  proteins are broken down into amino acids

  fats are broken down into fatty acids
• it is where feces are pushed out of

  anus
