Khan Academy on a Stick

Healthcare and medicine
  • Compliance and Elastance
    cc

    Learn about compliance (and elastance) of arteries, veins, and lead pipes! Rishi is a pediatric infectious disease physician and works at Khan Academy.

  • Bernoulli's equation of total energy

    Learn how total energy of a fluid helps explain why fluids can move from low pressure to high pressure! Rishi is a pediatric infectious disease physician and works at Khan Academy.

  • Stored elastic energy in large and middle sized arteries

    See how arteries behave like sling shots, shooting blood (not rocks) onwards! Rishi is a pediatric infectious disease physician and works at Khan Academy.

  • Compliance - Decreased blood pressure
    cc

    Find out how compliance allows arteries to store elastic energy (and lower pressure). Rishi is a pediatric infectious disease physician and works at Khan Academy.

  • Compliance - Increased blood flow

    Learn how compliant arteries allows for a "Constant Pressure System" like a modern water gun! Rishi is a pediatric infectious disease physician and works at Khan Academy.

Arterial Stiffness

Find out why having "stiff arteries" can increase blood pressure and cause uneven blood flow. It all comes back to the idea of "total energy"!
