What is the driving force for blood flow?
Understand the Problem
The question is asking about the mechanism or factors that cause blood to circulate throughout the body, typically focusing on concepts of pressure and the heart's role in the circulatory system.
Answer
Pressure gradient created by the heart
The driving force for blood flow is the pressure gradient created by the heart.
Answer for screen readers
The driving force for blood flow is the pressure gradient created by the heart.
More Information
The heart creates a pressure difference between arteries and veins through its contractions, propelling blood throughout the circulatory system.
Tips
One common mistake is to think that other factors like volume or gravity are the primary driving forces, but it is primarily the pressure gradient generated by the heart.
