Here we go. Nothing heavy for today, since it's a relaxation day. So, here's something easy. 5 Steps to Digestion.
Indigestion- Food starts its journey through the alimentary canal canal by entering the mouth.
That means, once you put the food in your mouth. That's indigestion! Fullstop! Period! End of story!
Digestion
- Food is broken down by enzymes into simpler substances to be absorbed by the small intestine.
Absorption- Food gets diffused by active transport in the small intestines.
Assimilation
- Nutrients of food get used by the body
e.g glucose for energy by respiration in cells
Egestion- Any undigested matter that passes through the alimentary canal will be passed out the body by the anus.
NOTE: Do not confuse EGESTION for EXCRETION.
Egestion = removal of anything UNDIGESTED by body e.g roughage/dietary fibre
Excretion = removal of METABOLIC WASTE by body e.g. expelling of carbon dioxide produced by cells during respiration.
