Metabolic Acidosis and Chloride

[nm825]

How does vomiting lead to low urine Cl-. Isn't because low volume triggers angiotensin II, angiotensin II increases sodium reabsorption, which thereby increases chloride reabsorption in the late proximal tubule?

Would ang II also stimulatie bicarb reabsorption in the early PT too? Wouldn't this make the alkalosis worse?

Also, when you vomit, you vomit up the contents of a stomach, which contains stomach acid or HCl. This HCl needs to be replaced, so the body will not be expelling too much chloride, while its replacing it.
