What food digests out?
4 Digestion works by moving food through
the gastrointestinal (GI) tract
. 4 Digestion begins in the mouth with chewing and ends in the small intestine. 4 As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules.
Which system that digest food and eliminate waste?
The digestive system
includes the digestive tract and its accessory organs, which process food into molecules that can be absorbed and utilized by the cells of the body. Food is broken down, bit by bit, until the molecules are small enough to be absorbed and the waste products are eliminated.
How the body eliminates waste or undigested food?
Your
large intestine
is the final part of your digestive tract. Undigested food enters your large intestine from your small intestine. It then reabsorbs water that is used in digestion and eliminates undigested food and fibre. This causes food waste products to harden and form faeces, which are then excreted.

Gastroparesis
is a disorder that occurs when the stomach takes too long to empty food. This disorder leads to a variety of symptoms that can include nausea, vomiting, feeling easily full, and a slow emptying of the stomach, known as delayed gastric emptying.
Why do we need to break the food that we eat?
Digestion is important for breaking down food
into nutrients
, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.
Where does unused food leave the body?
From the small intestine, undigested food (and some water) travels to
the large intestine
through a muscular ring or valve that prevents food from returning to the small intestine. By the time food reaches the large intestine, the work of absorbing nutrients is nearly finished.
How is food digested step by step?
There are four steps in the digestion process:
ingestion
, the mechanical and chemical breakdown of food, nutrient absorption, and elimination of indigestible food. The mechanical breakdown of food occurs via muscular contractions called peristalsis and segmentation.
What happens after the food is broken down into smaller pieces?
Food is taken into the mouth where it is broken down into smaller pieces by
the teeth

Where do faeces leave the body?
Your stool passes out of your body through
the rectum and anus

How do intestines help your body to remove semi solid waste?
The semi-solid waste is moved through the colon
by peristaltic movements of the muscle
and is stored in the rectum. As the rectum expands in response to storage of fecal matter, it triggers the neural signals required to set up the urge to eliminate.
What happens to the shape and size of your stomach when food goes into it as you eat a large meal?
Your stomach is an elastic organ, so when you take in a large volume of food, liquid, or air (think carbonation),
it does expand to accommodate everything that's put into it
. But it starts to shrink back to its normal size once the meal has passed out of the stomach.
