  2. Bicarbonate - Wikipedia

    en.wikipedia.org/wiki/Bicarbonate

    Bicarbonate (HCO − 3) is a vital component of the pH buffering system [3] of the human body (maintaining acid–base homeostasis). 70%–75% of CO 2 in the body is converted into carbonic acid (H 2 CO 3), which is the conjugate acid of HCO − 3 and can quickly turn into it. [citation needed]

  3. Bicarbonate buffer system - Wikipedia

    en.wikipedia.org/wiki/Bicarbonate_buffer_system

    The tears are unique among body fluids in that they are exposed to the environment. Much like other body fluids, tear fluid is kept in a tight pH range using the bicarbonate buffer system. [15] The pH of tears shift throughout a waking day, rising "about 0.013 pH units/hour" until a prolonged closed-eye period causes the pH to fall again. [15]

  4. Acid–base homeostasis - Wikipedia

    en.wikipedia.org/wiki/Acid–base_homeostasis

    An acid-base diagram for human plasma, showing the effects on the plasma pH when P CO 2 in mmHg or Standard Base Excess (SBE) occur in excess or are deficient in the plasma [23] Acid–base imbalance occurs when a significant insult causes the blood pH to shift out of the normal range (7.32 to 7.42 [ 16 ] ).

  5. Gastric acid - Wikipedia

    en.wikipedia.org/wiki/Gastric_acid

    A typical adult human stomach will secrete about 1.5 liters of gastric juice daily. [3] Gastric juice is the combination of gastric gland secretions including the main component of hydrochloric acid (gastric acid), gastric lipase and pepsinogen. [4]

  6. Metabolic acidosis - Wikipedia

    en.wikipedia.org/wiki/Metabolic_acidosis

    Metabolic acidosis is a serious electrolyte disorder characterized by an imbalance in the body's acid-base balance.Metabolic acidosis has three main root causes: increased acid production, loss of bicarbonate, and a reduced ability of the kidneys to excrete excess acids. [5]

  7. Renal compensation - Wikipedia

    en.wikipedia.org/wiki/Renal_compensation

    When the pH of the body falls below 7.35, an acidemia occurs. [2] Similarly, when the pH of the body rises above 7.45, an alkalemia occurs. [2] Renal compensation is one of the many compensatory mechanisms within the body which assist the pH level in ranging between 7.35 and 7.45 as the body cannot function properly when the pH falls out of ...

  8. Intracellular pH - Wikipedia

    en.wikipedia.org/wiki/Intracellular_pH

    Intracellular pH is typically lower than extracellular pH due to lower concentrations of HCO 3 −. [9] A rise of extracellular (e.g., serum) partial pressure of carbon dioxide (pCO 2) above 45 mmHg leads to formation of carbonic acid, which causes a decrease of pH i as it dissociates: [10]

  9. Chloride shift - Wikipedia

    en.wikipedia.org/wiki/Chloride_shift

    Bicarbonate in the red blood cell (RBC) exchanging with chloride from plasma in the lungs. The underlying properties creating the chloride shift are the presence of carbonic anhydrase within the RBCs but not the plasma, and the permeability of the RBC membrane to carbon dioxide and bicarbonate ion but not to hydrogen ion.
