autoregulation to maintain a constant glomerular filtration rate is achieved through the vasoconstriction of afferent arterioles when blood pressure is high. TRUE OR FALSE
Homework Answers
True
When blood pressure is high, blood volume is high, which increases GFR. To regulate this, vasoconstriction of afferent arterioles is achieved which reduces blood flow and controls Glomerular Filtration Rate.

Which of these statements about renal autoregulation using tubuloglomerular feedback is CORRECT? Increased blood pressure stimulates juxtaglomerular cells to release their hormone, cortisol, which stimulate DCT to reabsorb salt. Increased glomerular filtration rate stimulates macula densa cells to release their chemical signals that constrict afferent arterioles. Decreased flow of filtrate stimulates juxtaglomerular cells to release their hormone, angiotensin II, which is a vasodilator. Increased blood pressure stimulates atrial myocardial cells to release their hormone, atrial natriuretic peptide, which decreases glomerular...
