THE NUTRIENTS IN FOOD
Food contains the nutrients we need to
grow. There are 5 types of them:
1. CARBOHYDRATES: They give us energy.
2. FATS and SUGARS: They help our body
stores extra energy for when we need.
3. PROTEINS: They help our body, hair or
nails grow. They also repair body tissues.
4. VITAMINS and 5. MINERALS: They help
us to be healthy.
* We need to drink water. More than half of
our body is water

OUR DIGESTIVE SYSTEMIt helps us to get the nutrients we need
from food.
It is made up of:
1. the mouth: with the teeth and the
tongue.
2. the oesophagus: a long tube.
3. the stomach: like a bag.
4. the small intestine: is a very long thin
tube.
5. the large intestine: is a wide tube that
connects to the anus.

HOW DOES THE DIGESTIVE SYSTEM
WORK?In the MOUTH, the teeth break the food into small pieces and the tongue mixes the food with saliva.
In the OESOPHAGUS , food goes down here to the stomach.
In the STOMACH, gastric juices break down the food and turn it into a thick liquid. This liquid goes into the small intestine.
In the SMALL INTESTINE , there are a lot of blood vessels around it. The liquid goes through it and the nutrients pass into the blood.
In the LARGE INTESTINE, what our body doesn’t need goes through it and out through the anus.
THE EXCRETORY SYSTEMIt eliminates waste matter.
It is made up of
Two kidneys
Two ureters
The bladder
The urethra
THE EXCRETORY SYSTEMThe kidneys remove the waste matter from
the blood and turn it into urine.
The ureters are thin tubes that connect the
kidneys and the bladder.
The bladder is a bag which contains urine.
When ii is full we know that we have to go to
the toilet.
The urethra is a short tube. It connects the
bladder with outside the body.
