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.
A pulmonary lobule is the portion of the lung ventilated by one bronchiole. Bronchioles are approximately 1mm or less in diameter and their walls consist of ciliated cuboidal epithelium and a layer of smooth muscle. Bronchioles divide into even smaller bronchioles, called terminal, which are 0.5mm or less in diameter.he diameter of the bronchioles is often said to be less than 1 mm, though this value can actually range from 5 mm to 0.3 mm. As stated, these bronchioles do not have hyaline cartilage to maintain their patency. Instead, they rely on elastic fibers attached to the surrounding lung tissue for support.
