Interconnected Muscles
Let's experiment to see the action of interconnected muscles. Put your right hand on a table flat with palm facing upwards. Now you raise your middle finger slowly.
Try to touch your palm with it. You will find that the index finger and the ring finger also begin to rise. This shows that muscles of these fingers are inter-connected.
Sweat and the Cooling of Our Body
Take a little water and then wet your fingers. Then blow some air on the wet surface.
The water will evaporate fast. You will have a cool feeling over there. This is how your body cools itself.
When it gets warmed up, sweat glands produce sweat which evaporates from the body surface making the body cool.
