Normally, pulmonary arterioles are devoid of mural smooth muscle; however, chronic pulmonary vasoconstriction, as seen in COPD and cystic fibrosis, causes the arterial smooth muscle to extend into the arterioles.
Textbooks about the brain often point to star-shaped cells called astrocytes as the middlemen that carry the message--"more blood, please"--from neurons to arterioles.

The development of renal failure due to arterial hypertension is believed to result both from ischemia due to changes in preglomerular arteries and arterioles and from the effects of increased intraglomerular pressure (hyperperfusion), which inevitably leads to functional and subsequently structural glomerular changes and progressive loss of renal function.
Detailed histologic examination of other tissues revealed larvae embedded in arterioles in the gastrointestinal serosa, lung, and heart, which were associated with a significant granulomatous response.
