THE HUMAN BODY EXPLAIN THE PURPOSE OF THE MAJOR ORGAN SYSTEMS IN THE HUMAN BODY (DIGESTION, RESPIRATION, REPRODUCTION, CIRCULATION, EXCRETION, MOVEMENT,

THE HUMAN BODY

EXPLAIN THE PURPOSE OF THE MAJOR ORGAN SYSTEMS IN THE HUMAN BODY (DIGESTION, RESPIRATION, REPRODUCTION, CIRCULATION,

EXCRETION, MOVEMENT, CONTROL AND COORDINATION, AND FOR PROTECTION FROM DISEASE)

THE PROCESS OF MAINTAINING A FAIRLY CONSTANT INTERNAL

ENVIRONMENT DESPITE CHANGING CONDITIONS;

IT IS HOW WE “REGULATE” OURSELVES SWEATING, DRINK WATER, EXCRETION, SHIVERING

“CIRCULATION IS THE KEY”

A TRANSPORT SYSTEM FOR MANY SUBSTANCES;

INTERACTS WITH THE DIGESTIVE AND

RESPIRATORY SYSTEMS

CIRCULATORY SYS

MAJOR PARTS HEART, VEINS, ARTERIES AND CAPILLARIES, BLOOD

DIGESTIVE SYS“EATING & ELIMINATION”

BREAKS DOWN FOOD INTO SMALLER PIECES THAT CAN BE USED BY YOUR CELLS; DIGESTION CAN HAPPEN

TWO WAYS: MECHANICALLY AND CHEMICALLY

DIGESTIVE SYS

MAJOR PARTS TONGUE, TEETH, SALIVARY GLANDS, ESOPHAGUS, STOMACH,

SMALL & LARGE INTESTINES, LIVER, PANCREAS, GALL

BLADDER

PROVIDES SUPPORT AND STRUCTURE FOR THE

BODY; MUSCLE ATTACHES TO BONES TO ALLOW FOR

MOVEMENT

SKELETAL SYS

MAJOR PARTS BONES, CARTILAGE, TENDONS,

LIGAMENTS

RESPIRATORY SYS“ALL ABOUT BREATHING”

THE MOVEMENT OF AIR IN AND OUT OF THE LUNGS

RESPIRATORY SYS

MAJOR PARTS NOSE, TRACHEA, BRONCHIAL

TUBES, LUNGS, ALVEOLI, DIAPHRAGM

IMMUNE SYS“PROTECTING THE HOMEFRONT”

A COLLECTION OF CELLS AND TISSUES THAT DEFEND THE

HUMAN BODY AGAINST OUTSIDE INVADERS; TO

PREVENT DISEASE

IMMUNE SYS

MAJOR PARTS LYMPHATIC SYSTEM, SPLEEN, TONSILS,

BONE MARROW MAKES WHITE BLOOD CELLS

MUSCULAR SYS “MEAT ON THE BONES”

USED TO MOVE THE BODY, HELP CIRCULATE THE

BLOOD AND MOVE FOOD THROUGH THE DIGESTIVE

SYSTEM

MUSCULAR SYS

MAJOR PARTS INVOLUNTARY (SMOOTH), HEART

(CARDIAC) AND VOLUNTARY (STRIATED SKELETAL)

NERVOUS SYS“I’M SENSING SOMETHING”

THE CONTROL AND COMMUNICATION

NETWORK OF THE BODY; IT DETECTS AND RESPONDS TO STIMULI BOTH INSIDE AND OUTSIDE THE BODY

NERVOUS SYS

MAJOR PARTS BRAIN, SPINAL CORD AND NERVE

CELLS

EXCRETORY (URINARY)

REMOVES LIQUID WASTES FROM THE BODY

EXCRETORY SYS

MAJOR PARTS URINARY TRACT (KIDNEYS &

BLADDER), SKIN AND SWEAT GLANDS, BLOOD

VESSELS

REPRODUCTIVE SYS

NECESSARY FOR THE CONTINUATION OF A SPECIES

HUMAN REPRODUCTION INVOLVES TWO PARENTS, THE MALE AND THE FEMALE

FERTILIZATION HAPPENS WHEN THE SPERM AND EGG UNITE

SYSTEMS CAN’T WORK ALONE ! ! !
