How do the kidneys help to prevent blood pH from rising?
If blood pH is too low (ph < 7.35 ) = acidosis If blood pH is too high (pH > 7.45) = alkalosis In alkalosis: at the intercalated cells of the collecting duct the following occurs: secretion of Hco3- (via Hco3- / cl- antiporters) into the glomerular filtrate, which ultimately forms the urine. Rebsorption of Hydrogen ions (via ATPase dependant proton pumps)
What is the role of hydrogen ions in the conversion of ADP to ATP?
it is caused by the hydrogen ion flow across the membrane.
Acidosis results in increasing levels of what ion?
hydrogen ion
Excess hydrogen ions are removed from the blood by tubular secretion?
True
What is the anion responsible for buffering excess hydrogen ions to neutralize acidosis in the body?
The bicarbonate ion, HCO3-.
How does the body compensate for metabolic acidosis?
There are three ways the body compensates for acidosis and alkalosis. The major mechanisms are chemical buffers, respiratory systems and the urinary system
What would happen to urine pH if you increased secretion of hydrogen?
it would become more acidic

What happens if you get too much hydrogen in your body?
alkalosis? shock?
What is acidosis?
normal body pH is 7.35 to 7.45. Now there are certain conditions which alter this. In the most simplistic terms there are two main causes why the body would become acidotic ie its pH becoming less than 7.35. the first reason is when the lungs are not effectively removing the CO2 from the body, this is called respiratory acidosis. The second type is called metabolic acidosis and this occurs in severe sepsis, renal failure and drug overdoses. Either way if you are acidotic you are severely ill!

What is it called when the pH is greater than 7?
Anything with a pH greater than 7 is called a base. This is because pH measures the concentration of hydrogen ions in solution. Because a base usually has an ending of -OH (or hydroxide), there are more OH ions in solution than hydrogen ions.
If a blood test indicates someone is in severe acidosis are you trying to remove hydrogen ions or add them to her blood?
Acidosis is a condition in which the blood pH is too low, i.e. there is too high a concentration of protons. Thus the goal in treating acidosis is to lower the concentration of protons by treating with a mild base, usually sodium bicarbonate.
What substance can be eliminated from the blood by tubular secretion?
Potassiun ions. Hydrogen ions. Ammonium ions.
