How part of the theory of circulation was changed?
People used to think that blood could flow in any direction in the veins. William Harvey came up with evidence used to show that blood moved only in one direction through veins.

Which blood vessels in humans contain structures that allow ti flow in only one direction?
veins, they have valves, the reason why they have them is because blood flow is slow
What organ keeps blood flowing in one direction?

What is the advantages of large veivs having valves?
stops back-flow of blood through them so that the blood goes in one direction only
