digestive system

• The stomach is located between the esophagus and small intestine.
• The digestive system breaks down the food you eat
• Food is fuel
• Pyloric valves open so food can get into our small intestine
• Inside your stomach there is hydrochloric acid
• Your small intestine is 7 meters long
• Your large intestine is 2 meters long
• Peristalsis pushes food down your digestive tract without us thinking about it (involuntary muscles/smooth muscles)
• The purpose of the digestive system is to ingest, digest, absorb, and excrete food
• Inside your mouth you have salivary glands
• Salivary glands contain digestive enzymes
• Your teeth manually break down food
• Your throat aka pharynx attaches to your mouth and esophagus
• Your esophagus is your "food tube"
• Your esophagus uses peristalsis to push food down
• Your esophagus is attaached to your stomach
• Your stomach is attached to your small intestine
• Your small intestine is attached to your large intestine
• Your large intestine is attached to your rectum
• Your rectum is attached to your anus
• You have 3 accessory organs in the digestive system: the pancreas, liver, and gallbladder
• Your stomach holds and churns food
• Your stomach has a thick, protective mucous from the hydrochloric acid
• The small intestine absorbs nutrients from the food
• Nutrients are absorbed from food by diffusing through the wall of the small intestine into the bloodstream
• The large intestine absorbs water from indigestible food
• The rectum temporarily stores the remaining food waste and feces before it is expelled from the body
• The anus is the "exit door" for feces
• Accessory organs supply digestive enzymes for the digestive system
• The liver produces bile, a chemical which breaks down fat
• The gall bladder stores bile
• The pancreas produces pancreatic juice to break down carbs, fats, and proteins
• The digestive system uses oxygen from the respiratory system in order to break down foods into nutrients
• The digestive system gets food pushed along by muscles from the muscular system (peristalsis)
• The digestive system gives important nutrients to your bones (calcium and potassium)
• Nerves around the digestive tract allow the digestive system to function properly
• The circulatory system gets nutrients from the digestive system through diffusion
