Acid Base Balance Complete Test 2024.

Acid Base Balance Complete Test 2024. Concept of Acid-Base Balance -Critical to homeostasis & optimal cellular function -hydrogen ion concentration of body fluids must be kept within narrow range -hydrogen ions determine the relative acidity of body fluids -Acids release hydrogen ions in solution -Bases (or alkalis) accept hydrogen ions into solutions -Hydrogen ion concentration of a solution is measured as its pH normal ranges are 7.35-7.45. (7 is neutral). Normal pH indicates acid base balance. - correct answer -relationship between hydrogen ion concentration and pH is inverse; as H ion increases, the pH falls, and the solution becomes more acidic; as H ion falls, the pH rises, and the solution becomes alkaline or basic. -imbalance results from any one of several underlying causes and can be important clue in diagnosing illness or disease -failure to restore balance can lead to impairment of organs and critical bodily functions vary narrow tolerance for alterations in acid base levels Normal Acid-Base Balance - correct answer Metabolic processes in the body continuously produce acids, which fall into two categories: 1. Volatile Acids [eliminated from the body as a gas, carbonic acid (H2CO3) is only volatile acid produced in the body. It dissociates into carbon dioxide and water, and the lungs eliminate the CO2] 2. Nonvolatile Acids [all other acids produced in the body must be metabolized or excreted in fluid, lactic acid, hydrochloric acid, phosphoric acid, sulfuric acids] *Three systems work together to maintain pH within normal range:buffer system, respiratory systems, and the renal system
