Facts (generated by robot; please edit if you find it inaccurate)

• Vascular resistance is essentially under dual control, through systemic control via the autonomic nervous system and humoral factors and by local control via the conditions in the immediate vicinity of the blood vessels.
• A "large" defect may not have much flow across it if the pulmonary vascular resistance is high.
• Cold-induced elevation of forearm vascular resistance is inversely related to birth weight.
• Vascular resistance is decreased in the luteal rat ovary by a 20 minute continuous infusion of noradrenaline.
• Pulmonary vascular resistance is maintained at a high level with medial muscular hypertrophy of the pulmonary arterioles and occlusion of many smaller branches.
