Introduction:
The buffer resists the changes of the pH in a solution by converting the strong acid to the weak acid or the strong base to the weak base. Physiological as well as chemical buffer systems regulate the stabilization and homeostasis of the body pH.
Chemical buffer: It is a substance that binds to hydrogen ions and removes them from a solution when the concentration of hydrogen ions begins to increase or the substance releases hydrogen ions to the solution when the concentration of hydrogen ions begins to decrease. Within a second, the normal pH of the solution is restored by the chemical buffers. The chemical buffer systems are categorized into three types namely bicarbonate, the phosphate, and the protein systems.

Anatomy & Physiology: The Unity of Form and Function
- Definitions of acidosis and alkalosis are provided. In this system, what role do buffers play?arrow_forwardDetermine the type of acid-base imbalance and the corresponding compensation according to the following results from the arterial-blood-gas test. Blood pH: 7.25PCO2: 35 mmHgBicarbonate concentration: 18 mmol/L (b) Give one possible medical condition that leads to the acid-base imbalance in (a).arrow_forwardMetabolic acidosis is often treated by administering hydrogen carbonate intravenously. Explain how this treatment can increase blood plasma pH.arrow_forward
- given the pCO2 and pH of systemic arterial blood, be able to identify the type of acid-base imbalance (respiratory acidosis, respiratory alkalosis, metabolic acidosis, metabolic alkalosis). After identifying the type of acid-base imbalance, be able to determine what type of compensation will occur to restore pHarrow_forwardThree systems of the body help regulate acid/base balance - buffer system, respiratory system and renal system. Describe the renal response in a person experiencing metabolic alkalosis due to severe vomiting. Provide the general formula for pH control in acid/base regulation.arrow_forwarddefine buffer and write chemical equations for thebicarbonate, phosphate, and protein buffer systems;arrow_forward
- Explain thoroughly the Buffering Action of following Biological or Physiological Buffers:(a) Phosphate Buffer System.(b) Bicarbonate Buffer system.arrow_forwardWhat is the flow rate of a 100 mg/ 400 mL solution strength ordered to be infused at a rate of 20 mg/ h?arrow_forwardWrite the chemical equation for the carbonic acid–bicarbonate buffer system?arrow_forward
- Discuss thoroughly the renal regulation of acid-base balance in the body with the illustration of conservation of bicarbonate ion in the kidney.arrow_forwardWhat are the three chemical buffering systems, and where do they function?arrow_forwardOne type of diuretic given to people with high blood pressure, renal disease and congestive heart failure are thiazide-type diuretics. These drugs inhibit sodium ion reabsorption by inhibiting the transport in the ascending limb of the loop of Henle. A) What does it mean to inhibit the transport of sodium ions in the loop of Henle? B) Explain how this inhibition of sodium ions in the loop of Henle could help increase urine production.arrow_forward
