Pathophysiology OF PIH correct answers The normal response during pregnancy is to lower the
peripheral vascular resistance and to increase maternal resistance to the pressor effects of
Angiotensin II results in lowering the blood pressure.
Gradual loss of resistance to angiotensin II occurs for preeclampsia women.
Loss of normal pregnancy vasodilation of uterine arterioles and concurrent maternal vasospasm
results in decreased placenta perfusion.
Angiotensin II and blood vessels Effect correct answers drop in BP/drop in fluid volume
Renin release from the kidney
angiotensinogen -> renin acts on angiotensinogen to form angiotensin I.
ACE (angiotensin-converting enzyme) releases from the lungs
ACE acts on angiotensin I to form angiotensin II. *(angiotensin II also acts directly on the blood
vessels stimulating vasoconstriction - narrowing)*
Angiotensin II acts on the adrenal gland to stimulate the release of aldosterone.
Aldosterone acts on the kidneys to stimulate reabsorption of salt (NaCl) and water (H2O)
Pathophysiology Of PIH correct answers Normal renal perfusion is decreased with reduced GFR
