- List the three major chemical buffer systems of the body and describe how they resist pH changes.Discuss the role of buffers in helping the body maintain pH homeostasisIt is important to maintain optimal pH in the extracellular fluid otherwise illness and death can occur. Explain the mechanisms via which a pH level outside of homeostatic range negatively affects body function.
- During the study on Fluids, Electrolytes and Acid-Base Balance (Ch 26), we've looked at respiratory and renal acidosis/alkalosis concerns. The amount of CO2 and HCO3- in the blood triggers mechanisms to help balance blood pH so that the environment for normal biochemical reactions taking place in the body is present. The use of buffers helps to make sure that the body's environment is just right so that all internal functions are working. The kidneys do much more than help regulate the amount of CO2 and bicarbonate in the body. The Removal and Regulation functions of the kidneys includes electrolyte balance to make sure all organ systems can function. Below is a list of electrolytes regulated by the kidneys: Sodium - Na+ Potassium - K+ Phosphate - PO43- Chloride - Cl- Calcium - Ca2+ Magnesium- Mg2+ Conditions of excessive amounts or too little amounts create abnormalities. Some of these abnormalities (hyper- or hypo- conditions) can be life threatening. Directions for the…Metabolic alkalosis refers to a process whereupon decreased hydrogen ion, or increased bicarbonate, concentrations occur in the body, and the blood pH becomes too basic. Answer the following questions: How does the body regain its acid-base equilibria/balance? What happens when that balance does not happen? Will a buffer system still work under these conditions?explain briefly protein buffer in the body.
