Endocrine Regulation of Blood Pressure (Nursing)

00:01 Along with our neural controls, we also regulate blood pressure with hormonal controls.

00:08 Hormones regulate blood pressure in short term via changes in the peripheral resistance, or long term via changes in our blood volume.

00:18 This is stimulated by adrenal medulla hormones, such as epinephrine and norepinephrine that are released from the adrenal gland and increase cardiac output and vasoconstriction.

00:33 Angiotensin II, also an adrenal hormone stimulates vasoconstriction.

00:40 Antidiuretic hormone in high levels can also cause vasoconstriction and atrial natriuretic peptide will decrease blood pressure by antagonizing aldosterone, which causes a decrease blood volume.
