How acid-base balance maintains the balance of pH in the blood.

1. Exorete urine contain more H+

1.1. pH increase until homeostasis

2. pH low

2.1. More H+ (acidic)

2.1.1. Kidny(nephron)

3. pH high

3.1. Kidney ( nephroh )

3.1.1. Urine less H+ ions

3.1.1.1. H+ reabsorbed into blood

3.1.1.2. pH decrease

3.1.1.2.1. Will rise until hpmeostasis
