Explanation:

Question 130

To solve this, we recall the structures on the tongue: Cilia are hair - like structures (not on tongue for taste buds), rugae are folds in the stomach, villi are in the small intestine, and papillae are the small elevations on the tongue that support taste buds.

We analyze each hormone: ANH (Atrial Natriuretic Hormone) promotes sodium and water excretion, increasing urine. Aldosterone increases sodium reabsorption (decreasing urine), ADH (Antidiuretic Hormone) decreases urine by reabsorbing water. So ANH increases urine.

In the distal/collecting tubules, potassium, hydrogen, and ammonium are secreted. Sodium is reabsorbed (not secreted). So sodium is not normally secreted here.

Answer:

D. papillae
