The digestive system breaks down food into small pieces called nutrients. Our muscles and organs need the nutrients to give us energy and help us grow. Once the digestive system has extracted the nutrients, it gets rid of the waste.

esophagus

stomach

small intestine

liver

large intestine

anus

1. Digestion begins in the mouth. Food is broken up by the teeth and mixed with saliva by the tongue.

2. When you swallow the food, it travels through the esophagus to the stomach.

5. When the particles are in the small intestine, the juices from the liver and pancreas help break down those particles.

4. After the stomach, the food particles go to the small intestine. Here, the nutrients pass into the blood.

6. The particles that are not absorbed by the small intestine, reach the large intestine. The waste material goes out of your body.

The excretory system removes excess water and other waste products from our body.

kidneys

ureters

bladder

urethra

2. The urine (waste) goes down the ureters to the bladder.

The circulatory system carries oxygen and nutrients to all parts of your body, and removes waste products, like carbon dioxide.

heart
BLOOD VESSELS
Arteries, veins and capillaries are blood vessels.

Veins take carbon dioxide back to the heart.

Capillaries connect the arteries to veins.

The respiratory system takes in oxygen and expels carbon dioxide.

lungs

trachea

bronchi

nostrils

diaphragm

The alveoli are tiny sacs. Here is the place where the oxygen goes in and carbon dioxide goes out.

The nervous system receives information through the senses and gives responses through the locomotor system.

brain

nerves

spinal

The spinal cord carries signals between the brain and the rest of the body.

The brain is the most important organ. It receives signals and sends messages to the different parts of the body.

Each sense is linked to an organ or organs. Our senses send messages to the brain along the nerves.

The organ is the nose.

The organs are the ears.

The organ is the tongue.

The organ is the skin.

The organs are the eyes.

- Everyone has a unique odour identity. Only identical twins can smell the same way.

- Most people know the difference between 4,000 to 10,000 different smells.

- About 80 % of what we taste is through our sense of smell. This is why our taste decreases during a cold.

- Smell has a powerful link to memory.

- Our sense of smell is stronger in spring and summer because of the moisture in the air.

- The ear contains three areas: outer ear, middle ear and inner ear.

- The inner ear is where vibrations are converted to electrical impulses, which are transferred to the brain.

- There are five types of taste: salt, sweet, sour, bitter and umami.

- Children have more taste buds than adults.

- To distinguish taste, the brain uses about 20 % of the data from the taste buds and about 80 % from smell receptors.

- Foods like onions, garlic, spicy foods and hot foods can dull the sense of taste. Alcohol, smoking and caffeine also have the same effect.

- The skin has receptors that can feel pressure, moisture, temperature, vibration and pain.

- Most touch sensors send data to the brain.

- Pain can be one of the strongest memories we have. When we feel pain, we don´t repeat the same action.

- Our eyes can convert light into signals.

When the brain receives information from the senses, it sends a message to the locomotor system to respond.

The locomotor system is made up of the skeletal system and the muscular system.

The skeletal system is made up of bones and joints. Bones support our body, since they are hard. Did you know...? A baby has 300 bones, but an adult 206!

The skull protects your brain.

The ribs protect your heart and your lungs.

The pelvis protects the bladder and your reproductive organs.

The vertebrae protects and supports your spinal cord.

The muscular system is made up of more than 600 muscles. They can contract and relax, since they are elastic. Muscles and bones are connected with tendons.

The reproductive system allows us to have children. An egg is fertilised and after 40 weeks (over 9 months) it grows into a new human being.

At nine months it´s ready to be born.

When the baby is born, the umbilical cord is cut and becomes the belly button .
male reproductive organs
urethra

They are outside the body. Sperm travels from the testicles along the urethra and the penis to the outside.

penis

testicles
female reproductive organs
fallopian tubes

They are inside the body. Every month, an egg travels from the ovaries along the fallopian tubes, uterus and vagina to the outside. If it´s fertilised by a sperm, it stays in the uterus.

ovaries

uterus

vagina
