WebFick's law describes the movement of particles over time. There are a few strategies for maximizing particle movement, such as minimizing the distance the particles have to travel, using smaller molecules, increasing pressure, and increasing surface area. Fick's law can be expressed as an equation, but it is sometimes written in different forms. The Fick principle states that blood flow to an organ can be calculated using a marker substance if the following information is known: • Amount of marker substance taken up by the organ per unit time • Concentration of marker substance in arterial blood supplying the organ ibis on portland street
