Why Human Beings Are Complex Organisms

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.

3.  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.

4. are able to create and learn from experience. have language and thought

5. have a better developed brain than other life forms are endowed with intelligence which enables them to think and reason rationally and to differentiate right from wrong.

6. CELL ORGANISATION 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.

7.  EPITHELIUM CELLS NERVE CELLS (NEURONES) SPERMS EGG CELL (OVUM) RED BLOOD CELL

8. TYPES OF STRUCTURE FUNCTIONSSPECIALIASEDCELLS. epithelial #small and fit well together #cover the surface of the cells #can have hair like structures body line cavities and called cilia growing out from protect surfaces of organs them. #used in absorption and excretion of substances. nerve #very long and thread like #detect stimuli from the cell surrounding environment...
