Gastrointestinal System - Coggle Diagram
Gastrointestinal System
Anatomy
Mouth (oral cavity)
Entry point
Consists of lips cheek tongue teeth salivary glands
Teeth responsible for mechanical digestion thru breaking down food
Salivary glands secrete saliva to initiate chemical digestion
Tongue helps in food manipulation, processing and swallowing
Eusophagus
Muscle that connects mouth to stomach
Transport food from mouth to stomach
Liver
Largest internal organ
Produces bile that aids in fat digestion
Stores glycogen vitamins minerals
Stomach
Digestion of food
Gastric juices help break down protein
Churn food and create enzyme called chyme
Gallbladder
Stores bile
Pancreas
Produce digestive enzymes
Produce insulin
Large intestine
Absorbs water and electrolytes and forms feces
Good bacteria help in breaking down food and producing vitamins
Rectum stores feces
Small intestine
Longest part
Most of dogestion and enzyme absorption
Lining got villi and microvilli which aid in absoprtion
Physiological process
Food propulsion where swallowing and peristalsis occur
Food breakdown in stomack
Food breakdown and absorption in small and large intestine
age related changes
Tooth enamel and dentin gradually wear down, making teeth more
susceptible to cavities.
There is a decrease in saliva production
delayed emptying of food into the
stomach
Slowing of gastric emptying
decrease in enzyme peoduced so less absorption
decreased sphincter and muscle tone which delays movement and expulsion
Liver decreases in weight and size
gallstones increase in gallbladder
Less pamncreating enzymes created
