NUTRITIONNUTRIENTS GIVE TO OUR CELLS ALL ENERGY THAT THEY NEED

THE DIGESTIVE SYSTEM, THE RESPIRATORY SYSTEM, THE CIRCULATORY SYSTEM AND THE EXCRETORY SYSTEM CARRY OUT THE FUNCTION OF NUTRITION.

THE DIGESTIVE SYSTEM

IT HAS TWO PARTS, THE DIGESTIVE TRACT AND THE DIGESTIVE GLANDS.

THE RESPIRATORY SYSTEMTHE RESPIRATORY SYSTEM IS IN CHARGE OF BREATHING.

BREATHING MAKES TWO MOVEMENTS:

FIRST, WE INHALE AIR AND IT GOES INTO THE LUNGSTHEN, WE EXHALE AIR SENDING IT OUT OF THE LUNGS

THE EXCRETORY SYSTEM

THE EXCRETORY SYSTEM FILTERS WASTE SUBSTANCES FROM THE BLOOD. IT REMOVE THEM THROUGH EXCRETION.

THE EXCRETORY SYSTEM IS MADE UP OF:

SWEAT GLANDS

THE URINARY SYSTEM

THE URINARY SYSTEM

THE URINARY SYSTEM IS MADE UP OF:

THE KIDNEYS AND THE URINARY TRACT.

THE CIRCULATORY SYSTEM THE CIRCULATORY SYSTEM TRANSPORTS NUTRIENTS AND OXYGEN TO OUR CELLS, THERE ARE THREE TYPES OF BLOOD VESSELS: THE CIRCULATORY SYSTEM TYPES OF BLOOD VESSELS

ARTERIES

VEINS

CAPILLARIES

THE BLOODTHE BLOOD IS A RED LIQUID MADE UP OF CELLS THAT FLOAT IN A LIQUID CALLED PLASMA THERE ARE THREE TYPES OF BLOOD CELLS:

RED BLOOD CELLS?

WHITE BLOOD CELLS

PLATELETS

THE HEART

THE HEARTTHE HEART USES RYTHMIC SYSTOLE AND DIASTOLE MOVEMENTS TO PUMP THE BLOOD AROUND THE BODY.

FIRST: BLOOD ENTERS IN THE ATRIA.SECOND:PASSES TO THE VENTRICLES.THIRD:BLOOD COMES OUT THROUGH THE ARTERIES

THE HUMAN CIRCULATIONHUMAN CIRCULATION IS CLOSED AND DOUBLE.

HUMAN CIRCULATION IS CLOSED BECAUSE THE HEART SEPTUM SEPARATES THE TWO HALVES OF THE HEART. PULMONARY CIRCULATION

HUMAN CIRCULATION IS DOUBLE THE BLOOD FOLLOWS TWO ROUTES

SYSTEMIC CIRCULATION
