What are the differences between resistance vessels and capacitance vessel?

Resistance vessels, primarily arterioles, are responsible for regulating blood flow and maintaining blood pressure by providing resistance to blood flow. They have muscular walls that can constrict or dilate, thus controlling the distribution of blood. In contrast, capacitance vessels, mainly veins, serve as reservoirs for blood storage, holding a larger volume of blood with thinner walls and less muscle. They can expand to accommodate varying blood volumes, thus influencing venous return to the heart.
