THE HUMAN BODY AND NUTRITION

NUTRTION IN CELLSNUTRIENTSThe body transform The food into subtancesCalled nutrients

OXYGENWe breath in oxygenAnd breath out carbon dioxide

ENERGYIn cells the oxigenAnd nutrients are Cenverted intoenergy

WASTE SUBTANCES(go out)The body eliminates the Bad nutrients.

CIRCULATORY SYSTEM

RESPIRATORY SYSTEM

URINARI SYSTEM

DIGESTIVE SYSTEM

WHAT SYSTEMS ARE INVOLVED IN NUTRITION?

DIGESTION

• Is a process that transform the food into nutrients

ABSORPTION

• Nutrients pass to the blood thought capillares in the small intestine

EXCRETION

• Eliminates the nutrients that the body don’t need.

DIGESTIVE SYSTEM

1. THE DIGESTION BEGGINS IN THE MOUTH.THE TEETH BREAKS DOWN THE FOOD.THEN THE TONGE MIX THE FOOD WITCH SALIVA FROM SALARY GLANDS.THIS MIXTURE FORM A BOLUS.

DIGESTIVE SYSTEM PROCESS

2.THEN THE BOLUS TRAVEL DOWN THE PHARYNX AND GO TO THE OESOPHAGUS.

DIGESTIVE SYSTEM PROCESS

3.THEN THE BOLUS GO TO THE STOMACH.THE BOLUS MIX WITCH GASTRIC JUICES AND FORM CHYME.

DIGESTIVE SYSTEM PROCESS

4.CHYME GO TO THE SMALL INTESTINE,AND PASS TO THE LIVER.IN THE LIVER CHYME MIX WITCH OTHER JUICES(FOR EXAMPLE VILLIS)FROM PANCREAS ,LIVER,AND SMALL INTESTINE TO FORM CHYLE.

DIGESTIVE SYSTEM PROCESS

5.THEN IN THE SMALL INTESTINE OCURRED THE ABSORTION.NUTRIENTS PASS TO THE BLOOD THROUGH VEINS AND ARTERIES.

DIGESTIVE SYSTEM PROCESS

6.THE NUTRIENTS THAT THE BODY DON’T NEED GO TO THE LARGE INTESTINE THEN PAS TO THE RECTUM AND FINALY GO TO THE ANUS.

DIGESTIVE SYSTEM PROCESS

We breath in oxygen and breath out carbon dioxide.

PULMONARY VENTILATION I the movement of the air into and out of the lungs.THERE ARE TWO MOVEMENTS INSPIRATIONEXPIRATION

RESPIRATORY SYSTEM

THE DIAPHAGRAM CONTRACTS AND THE LUNGS WIDEN AND BACOME BIGGER.

WE TAKE IN OXYGEN

INSPIRATION

THE DIAPHGRAM RELEX AND THE LUNGS DEFLATE BECAUSE WE EXPULSE CARBON DIOXIDE.

EXPIRACION

THE RESPIRATORY SYSTEM BEGGEINS IN THE NOSE.

THE AIR ENTERS THOUGHT THE NOSTRILS.

RESPIRATORY SYSTEM PROCESS

THEN THE AIR TRAVELS DOWN THROUGHT:

LARYNXWINDPIPE/

TRAQUEABRONCHIBRONCHIOLESLUNGS

RESPIRATORY SYSTEM PROCESS

TRAQUEA

FINALY IN THE LUNGS THERE ARE ALVEOLI.

IT’S HERE THAT GAS EXCHANGE OCCURS.

ALVEOLI EXPULSE CARBON DIOXIDE.

RESPIRATORY SYSTEM PROCESS

RESPIRATORY SYSTEM

THE CIRCULATORY SYSTEM TRANSPORT NUTRIENTS AND OXYGEN THROUGHT BLOOD

CIRCULATORY SYSTEM

CIRCULATORY SYSTEM

BLOOD

PLASMA:FLUID THAT ALLOWS BLOOD TO MOVE

TYPES OF BLOOD CELLS

WHITE BLOOD CELLS

PLATELETS

REDBLOODCELLS

BLOOD VESSELS

VEINS ARTERIES

CAPILLARES

Transport oxygen and nutrients.Transportan oxygeno y nutrientes

RED BLOOD CELLS

Platelets are blood cells. Its function is to heal wounds and hemorrhages because they form clots. The bone marrow produces platelets.

Las plaquetas son celulas sanguineas.Su funcion es curar heridas y hemorragias por que se forman coagulos.La médula ósea produce las plaquetas.

PLATELETS

Defend from virusesDefienden de los virus.

WHITE BLOOD CELLS

COMPONENTS

VEINS:CARRY BLOOD TO THE HEART.ARTERIES:CARRY BLOOD AWAY FROM

YOUR HEART.CAPILLARES:CONNET VEINS AND

ARTERIES

BLOOD VESSELS

THE HEAT IS A MUSCULAR ORGAN.THE HEART HAVE 5 PARTS:TWO ATRIAS

TWO VENTRICLEVALVETHE MOVEMENT OF HEART IS HEARBEAT OR BEATING.HEARTBEAT HELPS THE HEART TO PUSH THE BLOOD

AROUND THE BODY.EACH BEAT HAVE

TWO PHASES.

THE HEART

IN BLOOD CIRCULATION THERE ARE TWO CIRCUITS:PULMONARY CIRCULATION:THE BLOOD TAKES TO

HEART TO THE LUNGS,AND BACK AGAIN.GENERAL CIRCULATION:THE BLOOD GO AROUN THE

BODY.

HOW YOUR BLOOD MOVES AROUND YOUR BODY

SYSTOLE: the heart contracts and send blood to arteries.

DIASTOLE: the heart relaxes and blood enters from the veins.

THE HEART

1.IN THE LUNGS THE BLOOD COLLET OXYGEN. THE OXYGEN LEAVES THE LUNGS AND TRAVELS TO THE HEART THROUGHT PULMMONARY VEINS.

2.THE CARBON DIOXIDE ENTERS IN THE HEART THROUGT VENA CAVA.

3.THE BLOOD TRANSPORT THE WASTE SUBTANCES TO THE KIDNEYS.

4.THE HEART SEND THE OXYGENATED BLOOD TO THE REST OF THE BODY THROUGT THE AORTA ARTERY.

HOW YOUR BLOOD MOVES AROUND YOUR BODY

ARTERIA AORTA

EXCRETORY SYSTEMKIDNEYS. Are organs that filter the blood And return the clean blood go back To the circulatory system.

URETERS.Two tubes that link the kidneysTo the bladder.

BLLADER.Is a muscular cavity Where urine is storaged.

URETHRA.Is a tube wich links the Bladder to the exterior.
