Veins are considered capacitance vessels because they collect 60-70% of the blood in systemic circulation. Small arteries and arterioles are considered resistance vessels because they represent where pressure is more greatly reduced.

Veins are often referred to as capacitance vessels because they have the ability to expand and store large volumes of blood. This capacity allows veins to serve as a reservoir to help maintain blood pressure and regulate blood flow throughout the body.
A series of vessels typically refers to a connected sequence of structures that transport fluids or materials within a system. This can include blood vessels in the circulatory system, vessels in the lymphatic system, or vessels used in industrial processes like pipelines or plumbing. The vessels are designed to efficiently and effectively channel the flow of substances from one point to another.
The windkessel vessel is a model used in physiology to describe the buffering function of the arteries in dampening the pulsatile flow of blood from the heart, creating a more continuous flow in the circulation. It helps to reduce fluctuation in blood pressure, ensuring more consistent blood flow to the tissues.
Yes, a metallic sphere of radius 1 cm can hold a charge of 1 coulomb. The amount of charge a conductor can hold is not dependent on its size but rather on its capacitance. For a spherical conductor, the capacitance (C) is directly proportional to the radius (r), so a larger radius would be able to hold more charge for the same potential difference.
