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.

TYPES OF SYSTEM IN HUMANBODY ORGANS : 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. DIGESTIVE FUNCTION: INHALES OXYGEN RESPIRATORY SYSTEM. AND EXHALE CARBON DIOXIDE. 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 BLOOD RECEIVE EXTERNAL NERVOUSCIRCULATORY STIMULI AND SYSTEM SYSTEM COORDINATES RESPONSES

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.
