Ans: No, Physical and bio-logical spheres do not follow totally different rules.
Thousands of years of observations and experiences reveal that the bio-logical world follows physical world; different organs of human body are reasonably compared to different parts of a machine.
We may cite of the examples regarding the similar functioning of a microchip and human brain, the sensors of an electronic device including an aircraft to the nerves of human body.
The rules of physics are universal indeed. A great many medical devices are based on mechanics, electronics and so forth belonging to the study of physics. Biology, especially human biology is greatly indebted to physics.
