WebIncreased renin release from the juxtaglomerular cells is caused by several conditions: reduction in renal blood flow from heart failure, blood loss, hypotension or ischemia of the kidneys, sodium diuresis (excessive sodium loss in urine), and beta-adrenergic stimulation. Increased renin levels are linked to several conditions, including: 1. Hypotension (low blood pressure). 2. Blood loss. 3. Lack of blood flow to your kidneys. 4. Volume depletion. 5. Sympathetic nerve activation (increased heart rate, breathing rate, blood pressure and pupil size). See more Yes.

Increase renin secretion

WebIf increased tubular reabsorption occurs in the proximal tubules or loop of Henle, prior to the macula densa, a salt-insensitive form of hypertension usually results. Increased tubular reabsorption prior to the macula densa tends to increase renin secretion and elicits a compensatory renal vasodilation that raises GFR and renal plasma flow. WebDec 1, 2009 · Increased renin secretion leads to increased ANG II levels and increased blood pressure. This mechanism is important to maintain systemic arterial pressure and tissue perfusion under conditions of reduced vascular volume. Influence of sympathetic nerves. The juxtaglomerular cells are innervated by sympathetic nerve fibers.
