Understanding diffusion processes and cardiac output measurements is crucial in fields like chemistry, physics, and medicine. Fick's laws provide the foundation for analyzing how particles move from areas of high concentration to low concentration, and for determining cardiac output based on oxygen consumption.

What is Fick's Law?

Fick's First Law states that the diffusion flux is proportional to the negative gradient of concentration. Mathematically:

J = -D (dC/dx)

Where:

• J is the diffusion flux
• D is the diffusion coefficient
• dC/dx is the concentration gradient
