1. If the Glomerular Filtration Rate (GFR) is low, what can the kidney do locally to restore homeostasis?

2. In glomerulonephritis, the normal filtration barrier is damaged and becomes far more permeable to plasma proteins, such as albumin along with other solutes. How would that affect glomerular filtration?

3. There are four hormones associated with renal regulation of blood pressure. Renin-angiotensin comes from the kidney itself, what are the other three and where do they come from. Give the name (or abbreviation) of the hormone and the organ or region that secretes it.

For example, renin-angiotensin comes from the kidney. Give the three other hormones that regulated blood pressure and the organ that secretes them. (I listed the hormones on the bottom, please help me figure out the organ or region that secretes it)
Antidiuretic Hormone (ADH)
Natriuretic Hormone
Parathyroid Hormone
