Due 2 atmospheric pressure of100000 pa,every 1 m sq of the
surface of any object experiences a force of100000n or
10000kgf which is roughly =10tonnes of force....
asuming the surface area of an adult is 2 m sq the force
experienced is 200000n or20 tonnes.....it iz becoz our
blood contains dissolved O2,which is at a pressure of more
than 200000pa. this pressure in the blood is commonly
called blood pressure which counterbalancrs the atmospheric
pressure..................
