Uterine blood flow was measured by the percentage distribution of radioactive microspheres injected into the left ventricle which lodged in uterus and placenta, and cardiac output was measured by dye … WebWhat is abnormal renin secretion? A hypotensive response, or lack of it, to angiotensin-converting enzyme inhibitor is similarly informative. Because the normal kidney exposed to high arterial pressure and normal salt intake will reduce its renin secretion to near zero, any renin secretion in a hypertensive setting can be considered abnormal. mag mo5collectall
