  2. Pulsatile flow - Wikipedia

    en.wikipedia.org/wiki/Pulsatile_flow

    The flow profiles was first derived by John R. Womersley (1907–1958) in his work with blood flow in arteries. [1] The cardiovascular system of chordate animals is a very good example where pulsatile flow is found, but pulsatile flow is also observed in engines and hydraulic systems, as a result of rotating mechanisms pumping the fluid.

  3. Womersley number - Wikipedia

    en.wikipedia.org/wiki/Womersley_number

    It is a dimensionless expression of the pulsatile flow frequency in relation to viscous effects. It is named after John R. Womersley (1907–1958) for his work with blood flow in arteries. [1] The Womersley number is important in keeping dynamic similarity when scaling an experiment. An example of this is scaling up the vascular system for ...

  5. Endothelial activation - Wikipedia

    en.wikipedia.org/wiki/Endothelial_activation

    Endothelial activation is a proinflammatory and procoagulant state of the endothelial cells lining the lumen of blood vessels. [1] It is most characterized by an increase in interactions with white blood cells (leukocytes), and it is associated with the early states of atherosclerosis and sepsis, among others. [2]

  6. Contractile vacuole - Wikipedia

    en.wikipedia.org/wiki/Contractile_vacuole

    The contractile vacuole is a specialized type of vacuole that regulates the quantity of water inside a cell.In freshwater environments, the concentration of solutes is hypotonic, lower outside than inside the cell.

  7. Phan Khôi - Wikipedia

    en.wikipedia.org/wiki/Phan_Khôi

    Phan Khôi was born in an elite Confucian family in Bảo An village, Điện Bàn county, Quảng Nam Province. His father was Phó bảng (Second-rank, under Doctorate) Phan Trân, a son of Nam Định Judge Phan Khắc Nhu. His mother was Hoàng Thị Lệ, a daughter of Hà Ninh Governor-general Hoàng Diệu. [3]

  8. Ventricular assist device - Wikipedia

    en.wikipedia.org/wiki/Ventricular_assist_device

    [13] [14] [15] In some pulsatile pumps (that use compressed air as an energy source [16]), the volume occupied by blood varies during the pumping cycle. If the pump is contained inside the body then a vent tube to the outside air is required. Continuous-flow VADs are smaller and have proven to be more durable than pulsatile VADs. [17]
