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

Answer options

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

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.
