Blood vessel radius has a larger effect on the body because changes in radius significantly impact blood flow resistance, which affects blood pressure regulation and delivery of oxygen and nutrients to tissues. Vessel length, on the other hand, has a smaller direct effect on blood flow resistance and overall cardiovascular function.
the capillaries are the most common blood vessel in the human body.
the main blood vessel in the body
The Blood Vessel Carries Useful Materials To The Cells And Tissues Of The Body.
Carrys Blood Through The Body
The aorta is the major blood vessel which transports blood from the heart to the rest of the body.

aorta
A blood vessel is a tube shaped organ that carries blood. It carries the blood through the tissues and organs of the human body.
They help in blood transport throughout the body
The Aorta pumps blood from the heart to the body.
Smooth muscle is mostly in the afferent branch going from the arteries to the arterioles. The body controls where blood will flow by controlling the vessel diameter. An increase in sympathetic tone constricts smooth muscle, decreases blood vessel diameter, and limits blood flow.
