This document provides information about nutrition and the digestive and respiratory systems in 3 paragraphs or less: Nutrition involves the processes that supply our bodies with building materials and energy through food. Foods provide nutrients like minerals, proteins, water, vitamins, fats, and carbohydrates. Carbohydrates provide immediate energy while fats supply slower energy and are stored as reserves. Proteins are needed for growth and repair, while vitamins and minerals aid health and growth. Digestion breaks down food for absorption. The digestive system involves the mouth, esophagus, stomach, small intestine, and large intestine. Food is broken down by teeth, saliva, stomach acids, and intestinal juices before nutrients are absorbed in

4. NUTRITION
Nutrition is the combination of processes which supply our body with the
building materials and energy we need to live.
Foods give us these nutrients.
Nutrients are the substances that your body needs in order to grow and stay
healthy.

5. Six categories of
nutrients:
- MINERALS
- PROTEINS
- WATER
- VITAMINS
- FATS
- CARBOHYDRATES

6. CARBOHYDRATES
Carbohydrates are turned into
energy for immediate use.
Pasta, bread, cereals, rice,
potatoes and pasta.

7. FATS
Fats provide a slower supply of
energy.
They are transformed into energy
reserves.
Oil, butter, chocolate…

8. FATS
ANIMALS FATS
eggs, fish, meat
VEGETABLES FATS
nuts and seeds

9. PROTEINS
Proteins are indispensable for us to
grow and repair our body.
Meat, fish, eggs, milk and pulses

10. VITAMINS AND MINERALS
Vitamins and minerals are essential
to stay healthy and grow.
Fruits and vegetables

11. WATER
Water to dissolve and transport
nutrients, and to compensate for
the water we lose when we sweat
or urinate.

12. PROCESSES INVOLVED IN NUTRITION
There are four processes involved in nutrition.
DIGESTIVE SYSTEM
RESPIRATORY SYSTEM
CIRCULATORY SYSTEM
EXCRETORY SYSTEM

13. DIGESTION
Digestion is the process of transforming the food we eat and drink into
the nutrients our body needs.
The digestive system carries out three important functions: digestion,
absorption and the elimination of waste.
It normally takes our body 24 to 48 hours to digest food.

14. 1. Digestion begins in our mouth.
Our teeth cut and chew our food,
and our tongue mixes it with saliva.
2. The food travels down the
oesophagus to the stomach.
3. In the stomach, the food mixes
with gastric juices, which break the
food down.
4. The mixture of food and
gastric juices travels through
the small intestine. Nutrients
from the food are absorbed
into our blood.
5. The parts of the food our body
does not need continue into the
large intestine.
6. The parts of the food our
body does not need leave our
body through the anus.

15. When we eat, we chew our food with our teeth, mix it with saliva, produced by the
salivary glands, with our tongue and swallow the mass of food, or food bolus. When
we swallow, the bolus is pushed into the pharynx and down the oesophagus.

16. The stomach mixes the food bolus, liquids and digestive juices for about two
hours. This produces a thick liquid called chyme.

17. In the small intestine the chyme mixes with juices from the
intestine, the pancreas and the liver, and makes the chyle.
The small intestine absorbs the nutrients you need to live and the
rest goes to your large intestine.
Small intestineLarge intestineFaeces leave the body
through the anus.

19. HEALTHY DIET
A complete balanced diet means
eating the right amount of food
from each of the food groups.

21. RESPIRATION
Breathing is the process that our body uses to
obtain oxygen from the air.
Respiration is the process by which we take in
oxygen and expel carbon dioxide.

22. THE RESPIRATORY SYSTEM
Nostrils

23. THE RESPIRATORY SYSTEM
When we breathe in, air enters our body through the nostrils, goes to the
pharynx, then travels down the larynx and trachea.

24. Next, air goes through two small tubes called the bronchi, and enters our
lungs.
TRACHEA
BRONCHI
LUNGS

25. The bronchi are divided into smaller branches called bronchioles. The
bronchioles lead to the air sacs.

26. https://www.youtube.com/watch?v=AJpur6XUiq4
Air sacs are covered by tiny
capillaries. When blood circulates
through these capillaries, red blood
cells take in oxygen and release
carbon dioxide. This process is called
gaseous exchange.
