Digestive System - Coggle Diagram
Digestive System
Anatomy of the digestive system
The stomach
where gastric juices are found and food is broken down into smaller molecules
Small intestine
completes the digestion of the food molecules
Duodenum
stimulates the digestion of fat and protein produces serotonin
Villi
Microvilli
forms vesicles and absorbs
creates large surface are for absorption of digested food molecules
Liver
produces bile and breaks up and digests fats
Gallbladder
where the extra bile is stored
Pancreas
produces pancreatic juices, produces lipase, amylase, and endopeptidase
Large Intestine
Chemical digestion is its main function and this is done via bacteria
It absorbs lots of water and feces is created with the extra food
Chemical Processes
Ingestion
Digestion
Mechanical
Physical breakdown of food
Chemical
Break down of large molecules, from polymers to monomers
Absorption
Transport
Chemical substances
Bolus
mixes with the gastric juices
Chyme
semifluid mixed with food found in the stomach
Transport mechanisms
Passive transport
Simple diffusion
Facilitated diffusion
Active transport
Endocytosis
Membrane pump
Hydrolysis
reaction used to break down large organic molecules
Peristalsis
smooth muscles move the food bolus through the canal
