Now let us look at the basic structure and functioning of this system – from the food entering the body through mouth, till it gets excreted in the form of feces, which is poop!
Well, this was all about the organs of the digestive system and their functions. So, just remember the order of the digestive system, the name of the organs, and their functions and you will be able to remember everything about this system easily.
The first part helps to soften the food, the second sends the food back to the mouth where it get chewed again, the third part removes moisture from the food, and the last which is fourth part mixes the food with digestive juices. Complex, right?
This causes the feeling of butterflies in the tummy. If you experience this, then just breathe deeply, and within minutes you will be okay.
However, when we don’t have food the rumbling sensation can be heard, because if there is food in the stomach the sound gets muffled.
