Physiology

Physiology. Cardiovascular System. Blood Flow. Mechanistic: Because the contractions of the heart produce a hydrostatic pressure gradient and the blood wants to flow to the region of lesser pressure. Therefore, the Pressure gradient ( ? P) is main driving force for flow through the vessels
