Vasopressin and aldosterone influence the activity of kidney by regulating the concentration of urine. Water permeability and concentration of urine is controlled by vassopressin and aldosterone by regulating the reabsorption of water in the collecting tubule. ADH released by the posterior pituitary triggers the release of aldosterone which further increases the concentration of sodium ions in the blood. The increased salt concentration in the blood increases the blood osmotic potential which further increases the reabsorption of water into the collecting tubule and thus the urine released is the concentrated one. In the absence of vassopressin, the water absorption in the cllecting tubules is less so the urine produced is dilute one.

So, the correct answer is 'Vasopressin and aldosterone'.

1. Hormones: The activity of the kidney is influenced by hormones such as aldosterone, antidiuretic hormone (ADH), and atrial natriuretic peptide (ANP). These hormones regulate the reabsorption of water and electrolytes in the kidney.

2. Blood pressure: The kidney plays a crucial role in regulating blood pressure. If blood pressure is too low, the kidney produces renin, which triggers the production of angiotensin II, a hormone that increases blood pressure. If blood pressure is too high, the kidney excretes excess sodium and water to lower blood pressure.

3. Diet: The activity of the kidney is influenced by the composition of the diet. A diet high in salt and protein can increase the workload of the kidney, while a diet low in salt and protein can reduce the workload of the kidney.

4. Drugs and toxins: Certain drugs and toxins can damage the kidney and impair its function. Examples include nonsteroidal anti-inflammatory drugs (NSAIDs), antibiotics, and heavy metals such as lead and mercury.

5. Age and health status: The activity of the kidney declines with age and may be compromised by certain health conditions such as diabetes and hypertension.
