Document Summary
An ace (angiotensin converting enzyme) inhibitor is a drug often used to slow the progression of renal failure. Ace decreases gfr by causing vasoconstriction of the afferent arterioles. Blocking angiotensin ii promotes excretion of na and fluids, decreased blood pressure. Ace normally converts a hormone called angiotensin i to a related hormone. Called angiotensin ii, which constricts blood vessels, increases sodium and water retention, the immediate net effect of these changes is to raise blood pressure, but over time this hormone can cause damage to the heart and kidneys. That makes sense: briefly describe dialysis and why it has become necessary for. Dialysis is used to artificially cleanse blood if kidneys are impaired. Uses a selectively permeable membrane to separate large and small solutes via diffusion. Hemodialysis - directly filtering the blood and returning it to the patient by using a hemo dialyzer (artificial kidney) that contains a dialysis membrane.
