Bronchial Artery

This is a micrograph of an inrapulmonary bronchus (cartilage islands, muscularis mucosae, submucosal glands). There are several bronchial blood vessels within the wall of this conducting air passage. These are “nutritive” blood vessels that carry oxygen and nutrients to the cells and tissues that make up the conducting passage. The most prominent of these vessel is the artery in the center of the picture. This is part of the systemic circulation and the wall thickness is comparable to that of other arteries of similar diameter in the rest of the body. PK1618. K4. H&E. Original mag. 25 x.
