Buffer solutions keep the ph constant in a wide variety of chemical actions. Acid base balance refers to the balance between input intake and production and output elimination of hydrogen ion.

Pdf Pathophysiology Of Acid Base Balance The Theory Practice Relationship

To maintain homeostasis the human body employs many physiological adaptations.

Acid base balances. The body uses different mechanisms to control the blood s acid base balance. The ph of the intracellular fluid and the extracellular fluid need to be maintained at a constant level. Respiratory regulation of acid base balance.

Your kidneys and lungs work to maintain the acid base. The respiratory system contributes to the balance of acids and bases in the body by regulating the blood levels of carbonic acid figure 26 4 2. Control of acid base balance the body s balance between acidity and alkalinity is referred to as acid base balance.

Many extracellular proteins such as the plasma proteins and membrane proteins of the body s cells are very sensitive for their three dimensional structures to. The body s acid base balance is tightly regulated to keep the arterial blood ph between 7 38 and 7 42. Your blood needs the right balance of acidic and basic alkaline compounds to function properly.

Whereas the respiratory system together with breathing centers in the brain controls the blood levels of carbonic acid by controlling the exhalation of co 2 the renal system controls the blood levels of bicarbonate. Co 2 in the blood readily reacts with water to form carbonic acid and the levels of co 2 and carbonic acid in the blood are in equilibrium. One of these is maintaining an acid base balance.

This is called the acid base balance. A buffer solution is a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. The renal regulation of the body s acid base balance addresses the metabolic component of the buffering system.

The body is an open system in equilibrium with the alveolar air where the partial pressure of carbon dioxide p co 2 is identical to the carbon dioxide tension in the blood. The blood s acid base balance is precisely controlled because even a minor deviation from the normal range can severely affect many organs. The proper balance between the acids and bases in the ecf is crucial for the normal physiology of the body and cellular metabolism.

Acid base homeostasis is the homeostatic regulation of the ph of the body s extracellular fluid. In the absence of pathological states the ph of the human body ranges between 7 35 to 7 45 with the average at 7 40.
