2 MAJOR CLASSIFICATIONS OF THE DIGESTIVE SYSTEM
A. FOOD TUBE/ALIMENTARY CANAL/DIGESTIVE TRACT
B. ACCESSORY ORGANS/GLANDS
DIGESTIVE SYSTEM- responsible for the breaking down of food into simpler molecules. ABSORPTION- bringing food to the body cells
DIGESTION-) the process of breaking down complicated chemicals in nutrients into forms that the body can use. ETYMOLOGY: Comes from the LATIN word DIGESTUS meanng to assimilate food. OTHER NAMES FOR THE SYSTEM:
DISEASE: Hemmoroid-also known as "almoranas" in Tagalog.
Salivary Amylase-enzyme secreted by the salivary gland
Gullet-technical term for esophagus
Stomach-temporary reservoir for partially digested food (the partially digested food is technically known as the bolus or chyme) Colon-technical term for the large intestine
Cardiac Sphincter and Pyloric Sphincter-they BOTH prevent the flowback of the food but each one of them performs a very important function. (Their functions can be seen in the Biology Textbook) 2 PHASES OF DIGESTION:
CHEMICAL PHASE AND MECHANICAL PHASE OF DIGESTION
under the MECHANICAL PHASE OF DIGESTION: we have Swallowing and chewing under the CHEMICAL PHASE OF DIGESTION: please refer to your Biology textbook *EGESTION(hndi ko lng sure kung ENGESTION or EGESTION s spelling)-opposite of ingestion, Egestion is the discharge or expulsion of undigested material (food) from a cell in case of unicellular organisms, and from the digestive tract via the anus in case of multicellular organisms.
