Describe the process of breathing

Social Studies

Breathing begins with inhalation when the contraction of the diaphragm flattens on contraction, pulling the lungs down. The contraction of these muscles increases the volume of the lungs. This reduces the air pressure in the lung to below that of the external air. This pressure difference forces air to move into the lungs where gas exchange occurs. The relaxation of the diaphragm and intercostals reduces the volume of the lungs, which then increases the air pressure inside the lung to that above the external air. This forces air out of the lungs. The cycle goes on and on. Hope this helped!

What can you do if you got married under false pretense?
Lerok [7]
False pretense must be interpreted by the courts and some circumstances automatically qualify as a false pretense, such as bigamy, when one of the parties is married already.  This breaks the marriage contract and qualifies for a voiding of the marriage.  Claiming to be 'with child', is a false pretense if a child is not born within 10 months of marriage. Impotence may qualify for a false pretense ruling under certain circumstances.   If the courts decide your marriage should never have taken place then you make seek an annulment.  The best advice is to visit a lawyer.
