HUMAN ARE COMPLEX

ORGANISM

WHAT IS THE PROOF

HUMAN ARE COMPLEX ORGANISMS THAT MADE UP OF MILLION INDIVIDUAL SYSTEMS.

SOME OF THE MAJOR SYSTEMS ARE THE BLOOD CIRCULATION, THE SKELETAL SYSTEM, THE DIGESTIVE SYSTEM, THE NERVOUS SYSTEM AND THE RESPIRATORY SYSTEM.

THE HUMAN BODY IS A COMPLEX SYSTEM OF CELLS, MOST OF WHICH ARE GROUPED INTO ORGAN SYSTEM THAT HAVE SPECIALISED FUNCTIONS. THESE SYSTEMS CAN BEST BE UNDERSTOOD IN TERMS OF THE ESSENTIAL FUNCTIONS THEY SERVE; DERIVING ENERGY FROM FOOD, PROTECTION AGAINST INJURY, INTERNAL COORDINATION AND REPRODUCTION.

Human are unique among earth’s life forms as they.

☺have language and thought ☺have a better developed brain than other life

forms.☺are able to create and learn from experience.☺are endowed with intelligence which enables

them to think and reason rationally and to differentiate right from wrong.

Cell in our body have different sizes and shapes and carry out various functions.

The process in which each type of cell is specialized to perform a specific functions is know as division of labor.

are able to create and learn from experience.

CELL THE CELL IS THE SMALLEST UNIT OF LIFE IN OUR BODIES

TISSUE A GROUP OF SPECIALISED CELLS, WITH THE

SAME FUNCTION.ORGAN TWO OR MORE TISSUES

CARRYING OUT THE SAME FUNCTION.

SYSTEM TWO OR MORE ORGANS CARRYING OUT THE SAME

FUNCTION.

CELL ORGANISATION

TYPES OF SIMPLE CELLS IN HUMAN BODY.

EPITHELIUM CELLSNERVE CELLS (NEURONES)SPERMSEGG CELL (OVUM)RED BLOOD CELL

TYPES OF SPECIALIASED CELLS.

STRUCTURE FUNCTIONS

epithelial cells

#small and fit well together #can have hair like structures called cilia growing out from them.

#cover the surface of the body line cavities and protect surfaces of organs#used in absorption and excretion of substances.

nerve cell

#very long and thread like #detect stimuli from the surrounding environment #transmit electrical signals to all parts of the body.

sperms

#look like a microscope tadpole #contains genetic information from the father.

#fertilizer an egg .Enabling information to be transfer from one generation to the next

egg cell (ovum)

#a large spherical cell#contains genetic information from the mother.

#after fertilizer by a sperm enables genetic information to be paused on from one generation to the next

red blood cell cell

Biconcave(a dip in the middle of each side.

#carry oxygen to all part of body.

TYPES OF SYSTEM IN HUMAN BODYORGANS :

MOUTH, OESOPHAGUS, LIVER, STOMACH, PANCREAS, LARGE INTESTINE, SMALL INTESTINE

RECTUM.

FUNCTION: DIGESTIVE SYSTEM CLASSES OF FOOD SO THAT THE NUTRIENTS CAN BE ABSORBED

EASILY BY THE BODY.

ORGANS: NOSE, TRACHEA, BRONCHUS

AND LUNG.

FUNCTION: INHALES OXYGEN AND EXHALE

CARBON DIOXIDE.

DIGESTIVE SYSTEM.

RESPIRATORY SYSTEM.

ORGANS: HEART, ARTERY AND

VEIN.

FUNCTION: TRNASPORT OXYGEN

AND FOOD TO ALL PART OF THE BODY

AND TRANSPORT EXCRETORY PRODUCTS.

ORGANS:BRAIN, SPINAL CORD NERVE.FUNCTION:

COORDINATES AND CONTROLS MOST

NERVE ACTIVITIES AND RECEIVE EXTERNAL

STIMULI AND COORDINATES

RESPONSES

BLOOD CIRCULATORY

SYSTEM

NERVOUS SYSTEM

EXCRETORY SYSTEM

ORGANS:LUNGS , SKIN, KIDNEY AND

BLADDER.FUNCTION: REMOVES EXCRETORY PRODUCTS

FROM THE BODYLUNGS: REMOVE CARBON

DIOXIDE AND WATER VAPOUR

KIDNEYS: REMOVE UREA , MINERAL SALTS AND

WATER.SKIN: REMOVE UREA, MINERAL SALTS AND

WATER.

MUSCULAR SYSTEM.

ORGANS: MUSCLE.

FUNCTION

ORGANS:LUNGS , SKIN, KIDNEY AND

BLADDER.FUNCTION: REMOVES EXCRETORY PRODUCTS

FROM THE BODYLUNGS: REMOVE CARBON

DIOXIDE AND WATER VAPOUR

KIDNEYS: REMOVE UREA , MINERAL SALTS AND

WATER.SKIN: REMOVE UREA, MINERAL SALTS AND

ORGANS: MUSCLE.

FUNCTION: ALLOW BODY MOVEMENT.

SKELETAL SYSTEM.

ORGANS: SKULL,PECTORA

L GIRDLE, RIB BONE,

BACKBONE, PELVIC GIRDLE,

FEMUR

FUNCTION:SUPPORTS THE BODY,

PROTECT INTERNAL ORGANS

AND ENABLES BODY MOVEMENT.

LYMPHATIC SYSTEM

FUNCTIONS:RETURN LYMPH TO THE

BLOOD STREAM AND PROTECT THE BODY

FROM DISEASE, CAUSE ORGANISMS.

ENDOCRINE SYSTEM.

ORGANS: PITUITARY GLAND, THYROID GLAND,

PANCREAS, ADRENAL GLAND, OVARY, TESTIS.

FUNCTION: PRODUCES

HORMONES AND COORDINATES AND

CONTROLS BODY RESPONSES TO

STIMULI AND LIFE PROCESSES SUCH AS REPRODUCTION AND

GROWTH.

Conclusion HUMAN ARE COMPLEX ORGANISMS

BECAUSE HUMAN MADE UP BY A MILLION IDIVIDUAL SYSYTEM. WITH OUT ALL THIS SYSTEM I THINK HUMAN CAN BE COMPLEX ORGANISMS AND HAVE THE SAME LEVEL WITH ANIMALS.

LOVE A OUR SELF BECAUSE WITHOUT ALL SYSTEM IN OUR BODY WE CAN’T MOVE, WALK AND DO THE OTHER ACTIVITY.
