Atria of a test animal were superdistended with blood, which resulted in decreased reabsorption of Na+ and water in renal tubules. This can be explained by the effect of the following factor on the kidneys:

Answer options

1. Vasopressin
2. Aldosterone
3. Angiotensin
4. Renin
5. Natriuretic hormone

Explanation

The natriuretic hormone is a hormone released from the heart muscles when there is high blood pressure, its release leads to increased release of sodium and water to reduce the high blood pressure. N.b: Natriuretic: Causing natriuresis, the excretion of an excessively large amount of sodium in the urine. A hybrid of the Latin natrium = sodium and the Greek enuresis = making water.
