PPT-Acid base balance Key points

For cells to function optimally a steady balance between the acids and the bases is necessary Acidbase balance represents homeostasis of hydrogen H ion concentration in body fluids . brPage 1br 91 points 91 points 91 points 91 points 91 points 91 points brPage 1br 92 points 92 points 92 points 92 points 92 points 92 points Definitions . Strong Acids. HCl. HBr. HI. HNO. 3. HClO. 4. H. 2. SO. 4. Acid: a species that supplies H. +. ions to water. Strong acid: an acid that completely ionizes in water forming an H. +. ion and an anion. 1. Mohammed A. Almeziny. . BPharm.RPh. . . Msc. . PhD. Clinical . Pharmacist. The Body and pH.

Why should we know about acid base disorders. What are acid base disorders. How to interpret acid base disorder. How to establish the cause. Why to worry about acid base disorders. Fluid, Electrolyte, and Acid-Base Balance. 1. Body Water Content. Infants have low body fat, low bone mass, and are 73% or more water. Total water content declines throughout life. Healthy males are about 60% water; healthy females are around 50%. Acid-base balance . (H. . production = loss). Normal plasma pH: 7.35–7.45. H. . gains: many metabolic activities produce acids. CO. 2. (to carbonic acid) from aerobic respiration. Lactic acid from glycolysis. 2009, Prentice-Hall, Inc.. Titration. In . this technique a known concentration of base (or acid) is slowly added to a solution of acid (or base. ).. The . analyte. - is the solutions being evaluated and is of unknown concentration.. M. . Gardner. Copyright2/4/2013. ACID /BASE BALANCE. In order to meet homeostasis, the body fluids must maintain a stable chemical balance of hydrogen ions in body fluids.. This is done by regulating their acidity /alkalinity. . Lecture 5. Introduction. A complex system of chemical buffers together with highly specialized mechanisms of the lungs and kidneys continuously work together to ensure a precise balance of water, electrolytes, and pH in both the intracellular and extracellular compartments of the human body. .

Acid-base balance.  . * Acids are electrolytes that release hydrogen ions (H+) when they are dissolved in water.. * Bases are electrolytes are release hydroxide ions (OH-) when they are dissolved in water.. Acid. is defined as a substance which when dissolved in water gives hydrogen ions. (H +) . Examples.. Base is defined as a substance which when dissolved in water gives hydroxyl ions. (OH-) .
