Acid-base homeostasis

Acid-base homeostasis. Dr. MALIK ALQUB MD. PHD. pH. pH is a measure of the acidity or basicity of an aqueous solution. The importance of pH control. Blood pH Must be Kept Close to 7.4 Hydrogen ion is extremely reactive and effects many molecules which regulate physiological processes

Chapter 17 Physiology of the Kidneys

Chapter 17 Physiology of the Kidneys. Dr. David Washington. Glomerular Filtration. A person with a cardiac output of 5,600 ml/min would have a flow rate through the kidneys of about 1,200 ml/min, or 21% of the C.O. (renal fraction = = 21%)

L. Alkalinity

We have a bicarbonate buffer system in our bodies that make strong acids weaker and strong bases weaker. Bicarbonates in the bloodstream carry CO 2 out of our bodies Many life forms thrive on a small pH range and thus rely on a buffer system. L. Alkalinity .
