inferior border of the scapula is the
the lower tip is usually at the 7th or 8th rib
bisects the center of each clavicle at a point halfway between the palpated sternoclavicular and acromioclavicular joints.
midclavicular line
extends through the inferior angle of the scapula when the arms are at the sides of the body.

anterior axillary
a line continues down from the the posterior axillary fold where the latissimus dorsi muscle inserts the
posterior axillary
a line runs down from the apex of the axilla and lies between and parallel to the other two

why
the right lung because of the underlying liver.
