Detailed explanation-1: -When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.
Detailed explanation-2: -The ribcage moves upwards and outwards and expands. This results in increasing the volume of the chest cavity and reduces the pressure inside it as volume is inversely proportional to pressure. When the pressure inside the lungs reduces then the air from outside rushes into the lungs.
Detailed explanation-3: -Sit or lie in a comfortable place. Place one hand on your chest and one hand on your abdomen. Inhale through your nose for about 4 seconds, feeling your abdomen expand. Hold your breath for 2 seconds. Exhale very slowly and steadily through your mouth for about 6 seconds. More items
