7 Questions
What are the two hormones that regulate the GFR?
Renin–angiotensin-aldosterone system (RAAS) and Atrial Natriuretic peptide (ANP
What causes the juxtaglomerular complex (JGC) to release renin?
Decline in osmotic concentration of tubular fluid at macula densa
What does angiotensin II do in the nephron?
Stimulates secretion of aldosterone by adrenal cortex in the PCT and collecting tubules – increase Na+, Cl-, water reabsorption, loss K+
What is the function of renin in the Renin–Angiotensin-Aldosterone System?
Converts angiotensinogen to angiotensin I
What triggers the release of antidiuretic hormone (ADH)/Vasopressin?
Angiotensin II activation
What does atrial natriuretic peptide (ANP) do?
Inhibits secretion of aldosterone by adrenal cortex in the DCT and collecting tubules – decrease Na+, Cl-, water reabsorption, increase K+
Which of the following is not a stimulus that causes the juxtaglomerular complex (JGC) to release renin?
Increase in systemic pressures
