What can cause the GFR to go down? Is this always a bad thing?

Blood loss or dehydration. short term it can help prevent further blood loss or dehydration.

What happens to the pH of blood in high altitudes and why?

It becomes alkaline. You breathe deeper to get more O2, and that causes you to get rid of more CO2

What are the acid and base of the protein buffer system? Where is it found?

amino acids. amino is a weak base and the acid is ....acid. this buffering system is found in the blood plasma

What are the two parts of the Phosphate buffer system?Where is it found?

dihydrogen phosphate (H2PO4-)(weak acid) and monohydrogen phosphate (HPO42-)(weak base) It is found in the cells

Why does the kidney tightly control the reabsorption of water?

The water balance in the body, for homeostasis is has a narrow range

What is the Glomerular Filtration rate(GFR)?

The rate at which filtrate is produced in glomerular filtration. normal is 125ml/min

What is tubular maximum?

The maximum rate of reabsorption by active transport through the nephron tubules. (glucose and sodium)

Check

What are the three processes for changing the pH of blood?

least effective but fast is the buffer system in the blood, ventilation depth and rate, most effective but slow is H+ secretion in the kidneys
