OSMOSIS AND DIFFUSION

you  know that our body water is about 60 % of the total weight in the average adult?

 45-55% of an older adult.
70-80% of an new born infant.
97% of the early human embryo.

fluid intake:   ingested water   1200-1500mL.
                           
                           ingested food      800-1100mL.

                           metabolic oxidation 300mL.
     
                            Total       2300-2900mL.

fluid output:    kidney    1500mL.

   insensible loss through skin    600-800mL.

insensible loss through lungs  400-600mL.

          Gastrointestinal tract   100mL.

                             Total     2600-3000mL.


Now we'll look about what is Diffusion and osmosis.


Osmosis:  Movement of water from low solute concentration to high solute concentration.
  
Diffusion: Movement of solute from high concentration to low concentration.

eg: Tea bags.   When we put tea bag into a cup then tea which is inside the bag .it is  a solute that comes out and mix with water which is a solvent.is a example of diffusion. from high to low concentration.
 
and in osmosis  when we put tea bag into a cup fill with water.then water move in side the bag from low to high concentration.it is a example of osmosis.

so by this way we see that there are both things happen together at a same time when we put tea bag into a hot water cup. 

I hope it is clear now difference between osmosis and diffusion.  Thanks
