THE RESPIRATORY SYSTEM
The respiratory system is in charge of breathing.
THE RESPIRATORY SYSTEM
The respiratory system is in charge of breathing.
Breathing makes two movements:•First we inhale air and it goes to the lungs.

The respiratory system is made up of: The nostrils, the pharynx, the larynx, the trachea, the bronchi, the lungs and the diaphargm.
THE EXCRETORY SYSTEM
The excretory system filters waste substances from the blood.
THE EXCRETORY SYSTEM
The excretory system filters waste substances from the blood. It removes them from the body through excretion.

The excretory system filters waste substances from the blood. It removes them from the body through excretion.
The excretory system is made up of:

The excretory system filters waste substances from the blood. It removes them from the body through excretion.
The excretory system is made up of:•Sweat glands in the skin.

The excretory system filters waste substances from the blood. It removes them from the body through excretion.
The excretory system is made up of:•Sweat glands in the skin.•The urinary system. This is made up of the kidneys and the urinary tract.
THE CIRCULATORY SYSTEMThe circulatory system transports nutrients and oxygen to our cells. It is made up of the heart, blood and blood vessels.
THE CIRCULATORY SYSTEMThe circulatory system transports nutrients and oxygen to our cells. It is made up of the heart, blood and blood vessels.
The heart is a muscular organ that pumps blood all around the body.

The heart is a muscular organ that pumps blood all around the body.
The blood collects oxygen and nutrients. It transports them to all the cells in the body. It also collects waste substances and takes them to the sweat glands and the urinary system.

The blood vessels are tubes through which blood circulates.There are three types: arteries, veins and capillaries.

Blood is a red liquid tissue made up of cells that float in a liquid called plasma.

There are three types of cells:
•Red blood cells carry oxygen.• White blood cells remove bacteria and viruses from the blood.•Platelets are small fragments of cells that form blood clots.

THE HEART
The heart uses rythmic systole and diastole movements to pump blood all around the body:
