Let us consider four major functions of digestive system.
00:13
This four major functions of digestive system, let us in detail explain them.
00:24
Digestive system major function is it breaks down the food that we intake.
00:35
Put these broken down into energy and used for survival of a living organism.
00:48
This is the function of a digestive system and the digestive system includes gastrointestinal tract.
00:56
I'm using gi for gastrointestinal tract and accessory organs.
01:05
Accessory organs required for functioning of a digestive system.
01:14
Gastro -inestinal tract consists of oral cavity, pharynx, esophagus, esophagus, stomach, small intestine, and stomach, small intestine, and large intestine.
01:43
So let me write small and large intestine.
01:47
Constring the accessor organs present in the digestive system includes teeth, tongue, glandular organs like salivary glands, liver and pancreas.
02:10
These are the parts that we come across in a digestive.
02:16
System the parts that we come across in a digestive system.
02:31
Now let us consider the functions the digestive system performs.
02:41
The steps involved in digestive system major functions includes ingestion, then digestion that is processing by physical and chemical means, then absorption of the food that is digested, and defecation, that is excretion of the waste from the body.
03:03
Now, considering the first step, ingestion, that is in ingestion, we are going to take food, that is, digestive system helps us to take in the food through the mouth, that is ingestion.
03:22
Next comes digestion of the food.
03:26
The food that is ingested moves through the digestive tract and through the digestive tract the food that is digested moves through the digestive tract by a process known as peti -stylosis and this is possible with the help of movement of muscles in the gastrointestinal tract in the g .i.
04:04
Tract.
04:06
The movement of the muscles helps in movement of the food through the digestive system.
04:16
Apart from this food is also broken down during this process of movement it even involves breakdown of the ingested food that is ingested nutrients and even helps in elimination of the undigested waste from the body next let's move to the digestion which is related to the secretions, the enzymes, hormones and other substances that are present in the digestive tract help in digestion of the food.
05:06
They help to digest the food that is ingested or eaten.
05:16
Now hormones they help in release of digestive juices.
05:36
And signal the brain, provide signal to the brain when it is hungry or full and help in digestion of the food.
05:57
Next comes after secretion.
06:01
The next step is digestion here...
