Unformatted text preview: by the hypothalamus • ADH stimulates water reabsorption by the kidneys and vasoconstriction to cause an elevation of blood pressure Blood Pressure Control Natriuretic Peptides - Atrial Natriuretic Peptide • Produced by cardiac muscle cells • These hormones reduce blood volume and blood pressure ; promote water loss by the kidneys; block release of ADH, aldosterone, epinephrine, and norepinephrine; stimulate vasodilation - therefore, casue a dcrease in blood pressure • Natriuretic peptides are produced in response to increased pressure in the right atrium during diastole Blood Pressure Homeostasis Neural • Controlled by cardiac centers and vasomotor center of the medulla oblongata • Cerebral cortex; limbic system...
