Final answer:
Poiseuille's Law is a mathematical formula that describes the flow of blood through a blood vessel, based on the radius of the vessel, pressure difference, and viscosity. The formula is (π * ΔP * r^4) / (8 * η * L).
Step-by-step explanation:
Poiseuille's Law is a mathematical formula that describes the flow of blood through a blood vessel. It states that the flow rate of blood is directly proportional to the fourth power of the radius of the blood vessel and the pressure difference between the two ends of the vessel, and inversely proportional to the viscosity of blood.
The formula for Poiseuille's Law is:
Flow Rate = (π * ΔP * r^4) / (8 * η * L)
Where:
- Flow Rate is the volume of blood flowing per unit time
- ΔP is the pressure difference between the two ends of the blood vessel
- r is the radius of the blood vessel
- η is the viscosity of the blood
- L is the length of the blood vessel
