Digestive System
Muhtasari
Every meal you eat is far too big and far too solid to enter your blood. A bowl of rice, a piece of chicken, an apple: each is a mass of huge insoluble molecules. The digestive system is the body's processing line that takes food in at the mouth, breaks it down step by step along a long muscular tube, and delivers small soluble molecules into the blood so every cell can use them.
In this lesson you will tour the alimentary canal and its helper organs, and learn exactly what each region does. You will learn to use the five key words examiners reward: ingestion, digestion, absorption, assimilation and egestion, and to place every organ inside that story so you can answer 'what happens here?' for any part of the gut.
