Q. Sneha was asked to explain what happens in our body during breathing. The paragraph that she wrote had several mistakes. Identify the mistakes she made and underline them. this is what she wrote.
During inhalation, the ribs move up and outward and the diaphragm moves in. this movement decrease the space in our chest cavity and the air rushes in. During exhalation, the ribs moves down and inward and the diaphragm moves up. This movement increases the space in our chest cavity and the air is pushed out.

Assertion[A]: The space in your chest cavity increases, into which your lungs expand.

Reason[R]: When the diaphragm tightens and moves downwards, inhalation of air occurs.
