You also must decide how much to spend. Again, there's no set recommendation. In a survey of more than 1,000 people by retailmenot,respondents on average said gifts worth about $111 were appropriate for high-school graduates, $243 for someone earning a bachelor's degree and $256 for the recipient of a graduate degree.
Bronchopulmonary Segments The bronchopulmonary segments are the anatomic, functional, and surgical units of the lungs. Each lobar (secondary) bronchus, which passes to a lobe of the lung, gives off branches called segmental (tertiary) bronchi.
The right main bronchus may be considered as having (1) an upper (eparterial) part, from which the segmental bronchi for the upper lobe arise, and (2) a lower part, from which the segmental bronchi for the middle and lower lobes emerge (fig. 21-4). The left main bronchus divides into two lobar bronchi, one each for the upper and lower lobes. The upper lobar bronchus may be considered as having (1) an upper division and (2) a lower, or lingular, division. The right main bronchus, about 2.5 cm in length, is shorter, wider, and more nearly vertical than the left.
