HUMAN ARE COMPLEX ORGANISMS

DO YOU KNOW WHY HUMAN BEINGS ARE COMPLEX ORGANISMS ?

The human being is a complex organism to the fact that human is made up of many systems. The manner in which all these systems interact and complement each other is so difficult to understand. Their thinking is so advanced that they can create about anything, which isn't possible with any other organism.

THE VARIOUS TYPES OF CELLS WHICH ARE SPECIALISED TO PERFORM SPECIFIC FUNCTION

a)Reproductive cellsExample : SPERM CELL and EGG CELL.

b) Nerve CellsReceives and sends messages to all part of our

body.

c) Epithelial CellsIt can protect the cells that live below them.

THE VARIOUS TYPES OF CELLS WHICH ARE SPECIALISED TO PERFORM SPECIFIC FUNCTION

d) Muscle CellEnable our arms and legs to move.

e) Bone CellProtect our body.

f) Red Blood CellsTransport oxygen to our whole part of body.

e) White Blood Cells Kill the bacteria that get inside our body.

ORGANISM

Basic unit that makes up the human body.

Made up of the same type of cells that work together to perform a function.

Made up of different tissues that work together to perform a function.

Made up of different Made up of different organs that work together to perform a function.

Made up of different systems that work together.

THE IMPORTANTANCE OF CELL ORGANISATION IN THE HUMAN BODY

The importance of the organization of cells into organs and systems is that once cells are organized in this way, more complicated, higher-order forms of life are possible. Single-celled life, like the amoeba, is very basic.  To develop more complicated, higher-order forms of life, cells must be able to group together to form tissues and organs.  In this fashion cells give up the questionable autonomy that the simple amoeba posses to become part of a larger system in which cells "differentiate" to take on different jobs in a larger system of cells, becoming organs, thus making worms, fish, snakes, birds, dogs, monkeys, and people possible.

VARIOUS SYSTEMS IN THE HUMAN BODY

SKELETAL SYSTEM SUPPORT THE BODY. PROTECTS OUR ORGANS. ENABLE BODY MOVEMENT.

RESPIRATORY SYSTEM INHALES OXYGEN AND EXHALES CARBON DIOXIDE

DIGESTIVE SYSTEM DIGESTS FOOD SO THAT NUTRIENTS ARE ABSORBED EASILY BY THE

BODY.

MUSCULAR SYSTEM MOVES ARMS AND LEGS.

VARIOUS SYSTEMS IN THE HUMAN BODY

BLOOD CIRCULATORY SYSTEM TRANSPORTS OXYGEN AND FOOD TO ALL PARTS THE BODY. TRANSPORTS EXCRETORY PRODUCTS.

NERVOUS SYSTEM COORDINATES ALL THE BODY’S ACTIVITIES. RECEIVES EXTERNAL STIMULI AND RESPONDS.

REPRODUCTIVE SYSTEM PRODUCES REPRODUCTIVE CELLS

VARIOUS SYSTEMS IN THE HUMAN BODY

EXCRETORY SYSTEM REMOVES EXCRETORY PRODUCTS FROM THE BODY.

WHAT WILL HAPPEN IF ONE OF THE SYSTEMS FAILS TO FUNCTION?

If one or more system fails to function the other system starts to compensate by working harder. So it is important to be checked and evaluated by your medical professional, so that proper treatment and care can be provided. Our body is very complex and wise in recognizing if there is something wrong, but sometimes we tend to ignore it.

HAPPY ENDING !
