Flow is the amount of blood flowing through an organ, tissue or vessel at a given time. Perfusion is the flow per given volume or mass of tissue. Thus a large organ could have greater flow but less perfusion then a small one such as an ovary because the ovary receives much more blood per gram of tissue.

JudyPerfusion refers to the delivery of blood to a specific tissue or organ, typically measured in milliliters of blood per minute per gram of tissue. Flow, on the other hand, refers to the movement of a fluid (like blood) through a vessel or system, usually measured in milliliters per minute. In summary, perfusion is the specific delivery of blood to tissues, while flow is the movement of blood through vessels.

What is wasted perfusion?
Wasted perfusion refers to blood flow that does not contribute effectively to tissue oxygenation or metabolism. This can occur in conditions such as shock, where blood flow is directed away from vital organs, leading to tissue hypoperfusion despite adequate total blood flow. Monitoring markers of tissue perfusion, such as lactate levels, can help assess the degree of wasted perfusion.
What condition is necessary for electric charge to flow?
For electric charge to flow, there must be a potential difference (voltage) between two points in a conducting material. This difference in potential creates an electric field that exerts a force on the charges, causing them to move. Without a potential difference, charges will not flow.
What is the driving force for the flow of electrons in battery's?
potential difference between electrodes
What is the driving force for the flow of electron in batteries?
potential difference between electrodes
What does a current flow of electrons need?
Your question is not clear. A current is generated when a group of electrons flow through a conductor, and this happens when there is a potential difference between the 2 ends of the conductor. If you want to know how can we start the flow of electrons it is by creating a potential difference in between the 2 ends of the conductor.
