Answer 1

sorry for the late response.

The answer is: C) It increases pressure in the abdominal cavity and helps to expel abdominal contents.

The Valsalva maneuver is a technique in which a person exhales forcibly while keeping their mouth and nose closed. This increases pressure in the chest and abdominal cavity, which can be helpful in certain situations. For example, the Valsalva maneuver can be used to help people pass stool more easily, or to help clear mucus from the airways. It can also be used to help athletes improve their performance in certain activities, such as weightlifting or cycling. However, the Valsalva maneuver should not be performed excessively or without caution, as it can cause dizziness or fainting, and may worsen certain medical conditions.
