pH Scale: a measure of H+ • pH scale is logarithmic: each difference of 1 pH unit means a 10X difference in H+ concentration
3 Ways to pH Homeostasis • Cells and blood contain chemical buffersthat resist change in pH by bonding excess H+ or OH- ions • Kidneys increase pH by secreting H+ and other ions from blood during urine formation. • Respiratory system increases pH by removing CO2 from blood.
