  2. Bohr effect - Wikipedia

    en.wikipedia.org/wiki/Bohr_effect

    The Bohr effect increases the efficiency of oxygen transportation through the blood. After hemoglobin binds to oxygen in the lungs due to the high oxygen concentrations, the Bohr effect facilitates its release in the tissues, particularly those tissues in most need of oxygen. When a tissue's metabolic rate increases, so does its carbon dioxide ...

  3. Oxygen–hemoglobin dissociation curve - Wikipedia

    en.wikipedia.org/wiki/Oxygen–hemoglobin...

    This is known as the Bohr effect. [5] A reduction in the total binding capacity of hemoglobin to oxygen (i.e. shifting the curve down, not just to the right) due to reduced pH is called the root effect. This is seen in bony fish. The binding affinity of hemoglobin to O 2 is greatest under a relatively high pH.

  4. Hemoglobin - Wikipedia

    en.wikipedia.org/wiki/Hemoglobin

    This decrease in hemoglobin's affinity for oxygen by the binding of carbon dioxide and acid is known as the Bohr effect. The Bohr effect favors the T state rather than the R state. (shifts the O 2-saturation curve to the right). Conversely, when the carbon dioxide levels in the blood decrease (i.e., in the lung capillaries), carbon dioxide and ...

  5. Bohr model - Wikipedia

    en.wikipedia.org/wiki/Bohr_model

    The Bohr model of the hydrogen atom (Z = 1) or a hydrogen-like ion (Z > 1), where the negatively charged electron confined to an atomic shell encircles a small, positively charged atomic nucleus and where an electron jumps between orbits, is accompanied by an emitted or absorbed amount of electromagnetic energy (hν). [1]

  6. Human physiology of underwater diving - Wikipedia

    en.wikipedia.org/wiki/Human_physiology_of...

    Human physiology of underwater diving is the physiological influences of the underwater environment on the human diver, and adaptations to operating underwater, both during breath-hold dives and while breathing at ambient pressure from a suitable breathing gas supply.

  7. Bohr equation - Wikipedia

    en.wikipedia.org/wiki/Bohr_equation

    The Bohr equation helps us find the amount of any expired gas, CO 2, N 2, O 2, etc. In this case we will focus on CO 2 . Defining F e as the fraction of CO 2 in the average expired breath, F A as the fraction of CO 2 in the perfused alveolar volume, and F d as the CO 2 makeup of the unperfused (and thus 'dead') region of the lung;

  8. File:Bohr Model.svg - Wikipedia

    en.wikipedia.org/wiki/File:Bohr_Model.svg

    I created this file to be an SVG alternative to Image:Bohratommodel.png and Image:Bohr model Balmer 32.png. I did not draw the orbitals to scale like the latter diagram because I could not readily find information about the orbitals' radii. For some reason, the "+" on the nucleus is rendering off-centered. The SVG doesn't look like that.

  9. Freediving blackout - Wikipedia

    en.wikipedia.org/wiki/Freediving_blackout

    Freediving blackout, breath-hold blackout, [1] or apnea blackout is a class of hypoxic blackout, a loss of consciousness caused by cerebral hypoxia towards the end of a breath-hold (freedive or dynamic apnea) dive, when the swimmer does not necessarily experience an urgent need to breathe and has no other obvious medical condition that might have caused it.
