KROK 1 2019 – Question 179 · KROK (Medicine) · Physiology
A group of researchers aimed to study cardiac physiology found that overstretching of atria in the heart leads to decreased sodium reabsorption in the distal convoluted tubule and increase in glomerular filtration rate. Which of the following is the most likely cause of physiologic effects discovered by researchers?
- A. Angiotensin
- B. Renin
- C. Aldosterone
- D. Antidiuretic hormone
- E. Natriuretic peptide
Hint
Think about which signal reports atrial stretch from a high blood volume, and whether it should favor sodium retention or sodium loss and a higher or lower filtration rate.
