BIOL - How Food Gets Digested
Biology, alimentary canal, digestion, enzymes - IGCSE | IBDP | DSE | GCE | IAL | AP Biology
Digestion is the process of breaking down large, insoluble food molecules into small and soluble molecules.
The human digestive system consists of the alimentary canal and accessory organs.
After food is ingested through the mouth, it is chewed into a ball, called the bolus.
The food bolus moves down the digestive tract by peristalsis, which is a series of muscle contractions that moves the food bolus down the digestive tract.
