  2. Vascular resistance - Wikipedia

    en.wikipedia.org/wiki/Vascular_resistance

    Vascular resistance is the resistance that must be overcome for blood to flow through the circulatory system.The resistance offered by the systemic circulation is known as the systemic vascular resistance or may sometimes be called by another term total peripheral resistance, while the resistance caused by the pulmonary circulation is known as the pulmonary vascular resistance.

  3. Hemodynamics - Wikipedia

    The pressure drop of the arterioles is the product of flow rate and resistance: ∆P=Q xresistance. The high resistance observed in the arterioles, which factor largely in the ∆P is a result of a smaller radius of about 30 μm. [24] The smaller the radius of a tube, the larger the resistance to fluid flow.

  5. Hemorheology - Wikipedia

    en.wikipedia.org/wiki/Hemorheology

    Blood viscosity is a measure of the resistance of blood to flow. It can also be described as the thickness and stickiness of blood. This biophysical property makes it a critical determinant of friction against the vessel walls, the rate of venous return, the work required for the heart to pump blood, and how much oxygen is transported to tissues and organs.

    en.wikipedia.org/wiki/Work_of_breathing

    The normal relaxed state of the lung and chest is partially empty. Further exhalation requires muscular work. Inhalation is an active process requiring work. [4] Some of this work is to overcome frictional resistance to flow, and part is used to deform elastic tissues, and is stored as potential energy, which is recovered during the passive process of exhalation, Tidal breathing is breathing ...

  9. Arterial resistivity index - Wikipedia

    en.wikipedia.org/wiki/Arterial_resistivity_index

    The RI is altered not by vascular resistance alone but by the combination of vascular resistance and vascular compliance. [2] [3] Normal mean renal artery RI for an adult is 0.6 with 0.7 the upper limit of normal. In children, RI commonly exceeds 0.7 through 12 months of age and can remain above 0.7 through 4 years of age. [4]
