The human digestive system.
00:02
The human digestive system has the main function that is to absorb the nutrients which is present in the food material.
00:10
And this in turn is assisted by the use of enzymes which are secreted by the human body.
00:15
Besides enzymes, certain hormones are also involved with regard to this particular processes.
00:20
In order to carry out first important function that is called as mechanical digestion return as md, followed by chemical digestion return as cd.
00:28
So this mechanical digestion starts right from the oral cavity that is referred to be as the mouth and then this chemical digestion tends to start right from the stomach where the food content are in turn present for a longer period of time in order to be broken down into smaller pieces.
00:45
So here it is only the mechanical activity of the teeth which is in turn present in the mouth and this it is in turn passed onto the food pipe which in turn can also be alternatively referred as the esophagus and from which it is delivered to the stomach.
00:58
But in the stomach there are large amount of secretions which are in turn pulled up for example secretions from that of the liver it in liver is in turn added along with which the secretions from pancreas is in turn also supported so all of these secretions in turn with this acidic content of the stomach in turn can degrade the food content into smaller pieces very effectively because this acidic content is almost sufficient to degrade most of the product whereas the enzymes which are in turn present in the liver and also because.

Pancreas can help in effective digestion...
