Answer the following questions in brief.
How much pressure do we carry on our heads? Why don’t we feel it?
The pressure above our head is equal to the atmospheric pressure. It is a large amount of pressure that can crush our head. But it doesn’t happen. Many air filled cavities and blood filled arteries and veins create a pressure inside our body. This internal pressure can balance the atmospheric pressure just above the head. Thus, we don’t feel any pressure above our head.
