full_question: The loss of pericytes can lead to weakness and damage to these structures, which can in turn lead to retinopathy and blindness. Inhibiting the new development of these structures--for instance, by targeting VEGF--is central to a class of cancer-fighting drugs called angiogenesis inhibitors. In these structures, buildup of plaques can lead to atherosclerosis and, in the long term, stroke. These structures release nitric oxide to relax smooth muscles cells and induce vasodilation. For ten points, name these structures responsible for shuttling endocrine hormones and erythrocytes around the body. They include capillaries, arteries, and veins.
