Blood flow depends on various physiological factors, including blood vessel diameter, blood viscosity, and blood pressure. Additionally, factors such as cardiac output, peripheral resistance, and overall vascular health can influence blood flow in the body.
Factors that influence resistance to blood flow include the diameter of blood vessels (smaller diameter increases resistance), length of the vessels (longer vessels increase resistance), blood viscosity (thicker blood increases resistance), and turbulence within the blood vessels (increased turbulence increases resistance).

Factors that directly influence venous blood flow include venous pressure, intrathoracic pressure changes during respiration, skeletal muscle contractions, venous valves, and sympathetic nervous system activity. These factors help propel blood back to the heart against gravity.

The factors that influence the efficiency of pipe flow in a fluid system include the diameter and roughness of the pipe, the viscosity and density of the fluid, the flow rate, and the presence of any obstacles or bends in the pipe.
Glaciers flow due to the force of gravity pulling them downhill. Factors that influence their movement include the slope of the terrain, the thickness of the ice, and the presence of meltwater at the base of the glacier.
The human magnetic field is very weak, about 100 times weaker than the Earth's magnetic field. Factors that influence its intensity include the body's electrical activity, blood flow, and the presence of metal objects.
Valves
Blood flow is directly proportional to blood pressure, vessel diameter, and heart rate. When these factors increase, blood flow also increases, and vice versa.
