  2. pH - Wikipedia

    en.wikipedia.org/wiki/PH

    A strong acid, such as hydrochloric acid, at concentration 1 mol dm −3 has a pH of 0, while a strong alkali like sodium hydroxide, at the same concentration, has a pH of 14. Since pH is a logarithmic scale, a difference of one in pH is equivalent to a tenfold difference in hydrogen ion concentration.

  3. Blood - Wikipedia

    en.wikipedia.org/wiki/Blood

    Blood pH is regulated to stay within the narrow range of 7.35 to 7.45, making it slightly basic (compensation). [17] [18] Extra-cellular fluid in blood that has a pH below 7.35 is too acidic, whereas blood pH above 7.45 is too basic. [16] A pH below 6.9 or above 7.8 is usually lethal. [16]

  4. Bicarbonate buffer system - Wikipedia

    3] is the concentration of bicarbonate in the blood [H 2 CO 3] is the concentration of carbonic acid in the blood; When describing arterial blood gas, the Henderson–Hasselbalch equation is usually quoted in terms of pCO 2, the partial pressure of carbon dioxide, rather than H 2 CO 3 concentration. However, these quantities are related by the ...

  5. Acid–base homeostasis - Wikipedia

    en.wikipedia.org/wiki/Acid–base_homeostasis

    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]). An abnormally low pH in the extracellular fluid is called an acidemia and an abnormally high pH is called an alkalemia. [citation needed]

  6. Homeostasis - Wikipedia

    en.wikipedia.org/wiki/Homeostasis

    The bicarbonate buffer system regulates the ratio of carbonic acid to bicarbonate to be equal to 1:20, at which ratio the blood pH is 7.4 (as explained in the Henderson–Hasselbalch equation). A change in the plasma pH gives an acid–base imbalance. In acid–base homeostasis there are two mechanisms that can help regulate the pH.

  7. Hemodynamics - Wikipedia

    en.wikipedia.org/wiki/Hemodynamics

    For instance, anemia (low red blood cell concentration) reduces viscosity, whereas increased red blood cell concentration increases viscosity. It had been thought that aspirin and related "blood thinner" drugs decreased the viscosity of blood, but instead studies found that they act by reducing the tendency of the blood to clot. [26]

  8. Acidosis - Wikipedia

    en.wikipedia.org/wiki/Acidosis

    The rate of cellular metabolic activity affects and, at the same time, is affected by the pH of the body fluids. In mammals, the normal pH of arterial blood lies between 7.35 and 7.50 depending on the species (e.g., healthy human-arterial blood pH varies between 7.35 and 7.45). [citation needed]

  9. Buffer solution - Wikipedia

    en.wikipedia.org/wiki/Buffer_solution

    The relative concentration of undissociated acid is shown in blue, and of its conjugate base in red. The pH changes relatively slowly in the buffer region, pH = pK a ± 1, centered at pH = 4.7, where [HA] = [A −]. The hydrogen ion concentration decreases by less than the amount expected because most of the added hydroxide ion is consumed in ...
