WebSep 19, 2024 · Flow = Pressure gradient / Resistance. This demonstrates that as resistance increases, the pressure gradient must also increase to maintain the same rate of flow into the alveoli. Diameter. Poiseuille’s Law, also known as the Hagen-Poiseuille equation, gives us the relationship between airway resistance and the diameter of the … WebAirway resistance is the opposition to flow caused by the forces of friction. It is defined as the ratio of driving pressure to the rate of air flow. Resistance to flow in the airways depends on whether the flow is laminar or turbulent, on the dimensions of the airway, and on the viscosity of the gas. For laminar flow, resistance is quite low.

Is flow resistance and pressure drop the same for pipe? - Quora
WebFeb 24, 2024 · The Role of Venoconstriction in Resistance, Blood Pressure, and Flow. As previously discussed, vasoconstriction of an artery or arteriole decreases the radius, increasing resistance and pressure, but decreasing flow. Venoconstriction, on the other hand, has a very different outcome. The walls of veins are thin but irregular; thus, when … WebSection Review. Blood flow is the movement of blood through a vessel, tissue, or organ. The slowing or blocking of blood flow is called resistance. Blood pressure is the force that blood exerts upon the walls of the blood vessels or chambers of the heart. WebDrag (physics) ("air resistance"), fluid or gas forces opposing motion and flow. The inverse of Hydraulic conductivity, the ease with which water can flow through pore spaces or … easy checkerboard cake
