  2. Critical closing pressure - Wikipedia

    en.wikipedia.org/wiki/Critical_closing_pressure

    Critical closing pressure is the internal pressure at which a blood vessel collapses and closes completely. [1] When blood pressure falls below critical closing pressure, the vessel is unable to overcome external pressure (either from environment or vascular smooth muscle) and flow stops.

  3. Starling equation - Wikipedia

    en.wikipedia.org/wiki/Starling_equation

    The rate at which fluid is filtered across vascular endothelium (transendothelial filtration) is determined by the sum of two outward forces, capillary pressure and interstitial protein osmotic pressure (), and two absorptive forces, plasma protein osmotic pressure and interstitial pressure (). The Starling equation describes these forces in ...

  4. Coronary perfusion pressure - Wikipedia

    en.wikipedia.org/wiki/Coronary_perfusion_pressure

    The heart is supplied by coronary vessels, and therefore CPP is the blood pressure within those vessels. If pressures are too low in the coronary vasculature, then the myocardium risks ischemia (restricted blood flow) with subsequent myocardial infarction or cardiogenic shock .

  5. Mean arterial pressure - Wikipedia

    en.wikipedia.org/wiki/Mean_arterial_pressure

    In medicine, the mean arterial pressure (MAP) is an average calculated blood pressure in an individual during a single cardiac cycle. [1] Although methods of estimating MAP vary, a common calculation is to take one-third of the pulse pressure (the difference between the systolic and diastolic pressures), and add that amount to the diastolic pressure.

  6. Cerebral perfusion pressure - Wikipedia

    en.wikipedia.org/wiki/Cerebral_perfusion_pressure

    An alternative definition of CPP is: [1] = where: MAP is mean arterial pressure ICP is intracranial pressure JVP is jugular venous pressure. This definition may be more appropriate if considering the circulatory system in the brain as a Starling resistor, where an external pressure (in this case, the intracranial pressure) causes decreased blood flow through the vessels.

  7. Blood vessel - Wikipedia

    en.wikipedia.org/wiki/Blood_vessel

    Blood vessels function to transport blood to an animal's body tissues. In general, arteries and arterioles transport oxygenated blood from the lungs to the body and its organs, and veins and venules transport deoxygenated blood from the body to the lungs. Blood vessels also circulate blood throughout the circulatory system.

  8. Oscar Predictions 2013 - The Huffington Post

    data.huffingtonpost.com/2013/01/oscar-predictions

    Don't rely on bloviating pundits to tell you who'll prevail on Hollywood's big night. The Huffington Post crunched the stats on every Oscar nominee of the past 30 years to produce a scientific metric for predicting the winners at the 2013 Academy Awards.

  9. Compliance (physiology) - Wikipedia

    en.wikipedia.org/wiki/Compliance_(physiology)

    This physically means that blood vessels with a higher compliance deform easier than lower compliance blood vessels under the same pressure and volume conditions. [1] Venous compliance is approximately 30 times larger than arterial compliance. [2] Compliance is calculated using the following equation, where ΔV is the change in volume (mL), and ...
