To reiterate some of his most interesting feats of strength from the video below: 1  Leeâs striking speed from three feet with his hands down by his side reached five hundredths of a second. 2  His combat movements were at times too fast to be captured on film for clear slow motion replay during that time.
Muscles of Respiration. During quiet breathing, the predominant muscle of respiration is the diaphragm. As it contracts, pleural pressure drops, which lowers the alveolar pressure, and draws air in down the pressure gradient from mouth to alveoli.
Best Answer: There are two main sets of muscles involved in breathing. The first is the diaphragm which is a two part leaf muscle that pulls down and flattens, when this happens it also pulls down on the bronchials of the lungs and helps to straigten them out so that the air has a more laminer shot into the lungs.
