Lecture´s Description

If you want to gain an extensive comprehension of the acid-base regulation, then this is the right place for you. This sqadia.com medical V learning lecture will serve the objective to remove all the ambiguities you have. Acids and bases, various buffer systems encompassing bicarbonate, phosphate, respiratory and ammonia buffer system has been explicated. Moreover, quantification of acid-base secretion, metabolic acidosis and alkalosis along with their respective treatments have been highlighted.

Acids and Bases

In this lecture ´´Acid-Base Regulation´´ are explained. Section one is about ´´Acids and Bases´´. Educator's prime focus is explanation of Regulation of H+. After that discusses acids and bases. Then elucidates strong and weak acids and bases. Following this, normal H+ concentration and pH of body fluids is presented. Furthermore, buffers, lungs and kidneys are pursued. Lastly, buffering of H+ in the body fluid is highlighted.

Buffer Systems

To begin with, the educator discussed about the bicarbonate buffer system and its quantitative dynamics of it. Subsequently, phosphate buffer system, proteins as intracellular buffers in conjunction with the respiratory regulation of acid-base balance has been expansively elaborated. Moreover, expiration of CO2, alveolar ventilation, feedback control of H+ and respiratory acidosis is illustrated.

Renal Control of Acid-Base Balance

First and foremost, renal control of acid-base balance and renal secretion of H+ whereas, the reabsorption of HCO3- has been clarified. Furthermore, secretion of H+ in late distal and collecting tubules, combination of H+ with PO3- and NH3 buffers along with the ammonia buffer system has been explained. In the end, chronic acidosis has been highlighted.

Quantifying Renal Acid-Base Excretion

Section four is about ‘’Quantifying Renal Acid-Base Excretion’’. Firstly, quantifying renal acid-base excretion is discussed. After that regulation of renal tubular H+ secretion is explained. Then renal correction of acidosis is pursued. Moreover, educator tells that acidosis decreases HCO3−/H+ ratio. Subsequently, renal correction of alkalosis is elaborated. Lastly, HCO3−/H+ ratio in renal tubular fluid is highlighted.

Clinical Causes of Acid Base Disorders

Section five is about ‘’Clinical Causes of Acid Base Disorders’’. Educator begins by explaining clinical causes of metabolic acidosis. Then moves to the discussion of clinical causes of metabolic alkalosis.  Following this, comprehensive information about treatment of acidosis or alkalosis is given.
