PPT-Homeostasis Section 2: Acid-Base Balance

Acidbase balance H production loss Normal plasma pH 735745 H gains many metabolic activities produce acids CO 2 to carbonic acid from aerobic respiration Lactic acid from glycolysis. Janis Rusin APN, MSN, CPNP-AC. Pediatric Nurse Practitioner. Lurie Children’s Transport Team. Objectives. Discuss the mechanisms for maintaining normal acid-base balance. Define respiratory and metabolic acidosis and alkalosis. AP Biology. Homeostasis and the Environment. So far, we have looked at how homeostasis controls and regulates our bodies (removal of nitrogenous waste, immune system). . While these are good examples of homeostasis, they are at an organism or cellular level. . Putting it All Together When . Resources are Abundant. Stuart L. Goldstein, MD. Professor of Pediatrics. University of Cincinnati College of Medicine. Director, Center for Acute Care Nephrology. Nephrology and Hypertension. MLAB 2401: Clinical Chemistry. Keri Brophy-Martinez. Terms. Acid. Any substance that can yield a hydrogen ion (H. +. ) or hydronium ion when dissolved in water. Release of proton or H. +. Base. Substance that can yield hydroxyl ions (OH. Halvor M.

University of Central Arkansas Department of Biology. 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%. homeostasis. . Cells have different functions.. Homeostasis = stable environment in your body; balance. Your body maintains its homeostasis even if outside conditions are changing. . Levels of Organization. Diagnosis of acid base balance in diarrhoeic calves. Implementation in practice Dai Grove-White A historical perspective William O ’ Shaughnessy 1831 “I would expect much benefit from the frequently repeated use of the neutral salts by the mouth dissolved in large quantities of tepid water. In severe cases, in which 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. . For cells to function optimally, . a steady balance . between the acids and the bases . is necessary.. Acid-base balance represents homeostasis of hydrogen (H+) ion . concentration in . body fluids. . . Stasis. = . standing. Greek for “. standing still. ”. Homeostasis is…. “the state of balance within our bodies”. Living organisms require a balance of certain variables within their bodies to stay alive. . Many critical illnesses can disturb acid-base balance.. Acid-base disturbances may indicate an underlying disease or organ damage.. Accurate interpretation of acid-base disturbances requires the following:. Homeostasis –. Necessary Life Functions. What defines all living organisms?. Maintain. . boundaries. Movement. Locomotion. Movement of substances. Responsiveness. Ability to sense changes & react. 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-) . Examples..
