ayama | to lengthen or extend, remove restraints (lit. “stretching, extending”) |

capillaries | tiniest blood vessels in the body; small enough to allow oxygen and carbon dioxide to pass through thin membranes |
cellular respiration | cells taking in oxygen across their membranes and releasing carbon dioxide back out |

A= | the action of the diaphragm is to increase the volume of the thoracic cavity three dimensionally by approximating its upper and lower attachments |
S = | shape double dome shape convex cranially (concave caudally) |
L= | location the top is behind the nipples within the ribcage and the bottom extends to the lumbar spine behind the navel |
