Blood flows through arteries (from the heart), veins (to the heart) and capillaries. The heart pumps oxygenated blood out of the aorta and it circulates throughout the body providing oxygen to the muscles and organs (both voluntary and involuntary). The deoxygenated blood returns to the heart through veins. Veins have valves to stop blood flowing in the wrong direction. So the blood returns to the heart though both the superior and inferior vena cava and is then carried to the lungs where it is re-oxygenated, carried back to the heart and again pumped out the aorta. All in all the heart makes blood flow.

A blood flow is the blood pumped from the heart to all parts of body through arteries and flow back through veins.

A blood flow can also be normal menstruation, or a uterus vaginal problem.
