Digestive System
Gbogbo ọrọ náà
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.
Ebumnobi

- Describe the functions of the organs of the digestive system listed in 7.2.1, in relation to: (a) ingestion - the taking of substances, e.g. food and drink, into the body (b) digestion - the breakdown of food (c) absorption - the movement of nutrients from the intestines into the blood (d) assimilation - uptake and use of nutrients by cells (e) egestion - the removal of undigested food from the body as faeces
