Vagus Phrenic Brachial Pectoral Fibers of the parasympathetic division of the autonomic nervous system (ANS) travel only in the vagus nerve to the lung. What is the action of urodilatin? Urodilatin causes vasoconstriction of afferent arterioles. It causes vasodilation of the efferent arterioles. Urodilatin inhibits antidiuretic hormone secretion.Page 2 of 36 2 Question 3 2 / 2 pts Question 4 2 / 2 pts It inhibits salt and water reabsorption. Urodilatin (a natriuretic peptide) inhibits sodium and water reabsorption from the medullary part of collecting duct, thereby producing diuresis. It is not involved in the actions described by the other options. What is the direct action of atrial natriuretic hormone? Sodium retention Sodium excretion Water retention Water excretion Atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) inhibit the secretion of renin, inhibit angiotensin-induced secretion of aldosterone, vasodilate the afferent and constrict the efferent glomerular arterioles, and inhibit sodium and water absorption by kidney tubules.
