Digestive System
Biology
| Term | Definition |
|---|---|
| Nutrients | Carbohydrates, Proteins, Lipids, Vitamins, Minerals, Water |
| Mechanical Digestion | The process of mashing and grinding food |
| Chemical Digestion | The process of using enzymes to break down food |
| Hydrolysis | A chemical reaction where something reacts with water and is changed into a new substance |
| Ingestion | First stage of digestion...consume food |
| Digestion | The breakdown of food into smaller particles called nutrients that can enter cells |
| Absorption | Third stage of digestion...nutrients diffuse into blood and cells |
| Egestion | Fourth stage of digestion...elimination of solid wastes |
| Mouth | This is where digestion starts...site of mechanical digestion |
| Salivary Amylase | Enzymes present in the mouth that break down starches into disaccharides |
| Pharynx | Back of the throat |
| Epiglottis | This flap of tissue that closes to prevent food from passing into the trachea |
| Esophagous | Site of peristalsis |
| Peristalsis | Strong muscular contractions that push food along |
| Stomach | Site of both chemical and mechanical digestion |
| Hydrochloric Acid | I am present in the stomach to aid in the chemical digestion process |
| Sphincters | "Trap doors" that regulate the passage of food into and out of the stomach |
| Pepsin | Digestive enzyme in the stomach that catalyzes the breakdown of proteins to peptides |
| Chyme | Liquid leaving the stomach |
| Liver | I make bile and act as an emulsifier to break down fat into tiny droplets |
| Bile | Fluid secreted by the liver that aids in digestion |
| Gall Bladder | I store bile |
| Insulin | I lower blood sugar levels |
| Glucagen | I raise blood sugar levels |
| Sodium Bicarbonate | I am made in the pancreas and neutralize chyme entering the small intestines |
| Pancreatic Amylase | I am an enzyme found in the pancreas |
| Trypsin | Enzyme produced in the pancreas and aids digestion in the small intestines...hydrolyzes proteins to smaller polypeptides |
| Lipase | Enzyme produced in the pancreas and aids digestion in the small intestines...hydrolyzes fats into fatty acids and glycerol |
| Small Intestines | Final site of chemical digestion |
| Villi | Tiny finger-like projections that line the small intestines...site of nutrient absorption |
| Maltase, Sucrase, Lactase | Enzymes found in the intestines which break down disaccharides into monosaccharides |
| Peptidase | Any enzyme that acts a s a catalyst in the splitting of a peptide into an amino acid |
| Large Intestines (colon) | I remove water from undigested food to form feces |
| Rectum | Stores feces |
| Anus | Exit for feces |
| Emulsification | The breakdown of large fats into tiny fat droplets to provide a larger surface area for lipase to act. |
| Pancreas | Organ located in the abdomen. It plays an essential role in converting the food we eat into fuel for the body's cells. |
