INHALE !
cause during inspiration, the external intercostal muscles contract. the ribs are raised upwards and outwards. the thoracic cavity enlarges from side-to-side. the breastbone moves slightly forward. the thoracic cavity increases from front-to-back. the diaghragm becomes flattened due to the contraction of the muscles in it. this causes the thoracic cavity to enlarge in a top-to-bottom direcction. this 3-dimensional expansion of the thoracic volume decreases the air pressure. thus air is forced into the lungs!
yay they say that the volume of air entering or leaving the lungs during normal breathing, also called the tidal air, is about 500cm3. but the total vital capacity of the lungs is 3500-4000cm3! this is when we take the deepest breath!
so let's all stretch the vital capacity of our lungs as we ENLARGE and EXPAND OUR TERRITORIES ! CONQUER NEW GROUNDS WITH THE SWORD OF FAITH (:
