GNUR 293 - Exam 2 Study Guide/GNUR 293 - Exam 2 Study Guide Acid-Base Homeostasis and Imbalances Describe how volatile and nonvolatile acids are buffered and/or removed from the body, from first to last to respond, in order to maintain homeostasis and maintain a blood pH of 7.35-7.45. o Volatile acids: undergo vaporization rapidly. Carbonic acid is a volatile acid that forms inside our body from carbon dioxide and is excreted via the lungs. o Nonvolatile acids: Cannot undergo vaporization rapidly aka metabolic acids. Produced from sources other than carbon dioxide. Excretion via the kidney. Regulators: o Buffers: immediate reaction Act chemically to neutralize acids or change strong acids to weak acids. Cannot maintain pH without adequate respiratory and renal function Includes: Carbonic acid/bicarbonate buffer system (primary defense against acid/base disorders) Hemoglobin/oxyhemoglobin buffer
