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

Answer options

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

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.
