Human digestive system

Also referred to as alimentary canal, alimentary tract, gastrointestinal tract and gastrointestinal system

The human digestive system or gastrointestinal tract is complex. The digestive tract (also referred to as alimentary canal) consists of digestive organs that take in food.

This digestive tract or alimentary canal processes (digests) food to get the required nutrients for the body and expels the remaining waste material.

Do we need to know our digestive system to digest food?

We don't really need to know and understand how the digestive system works, unless you are studying to be a doctor.

Even a new born baby digests it's food without knowing anything about the digestive system or digestive process.

The whole digesting process happens without much interference from us. So we tend to take it for granted.

It is when things start going wrong that we want to know the 'how' and 'why' about our body in general and digestion in particular.

It is when we start having digestive problems such as acid indigestion, heartburn, constipation, stomach bloating, stomach gas, flatulence etc., we want to know how and why and where things are wrong. And if we can set them right.

Many of us also feel helpless and think that we just have to endure / tolerate these problems and accept them inevitable as a part of growing old or 'that is how life is'.

The possibility of improving our digestive system with some changes in food and eating habits does not seem real to many. When you know how the digestive system works, you can at least try to make some changes in your diet and eating habits to improve it.

These changes may not happen overnight. But they may make your digestive health better and that is bound to make your life better too. It is worth learning and understanding the digestive process.
