Open systems refer to systems that interact with other systems or the outside environment, whereas closed systems refer to systems having relatively little interaction with other systems or the outside environment.
An open system is where the blood freely diffuses through an organisms body. As humans, we are far too large for that. We would certainly die before the oxygen and nutrients could diffuse to the inner regions. So we have a closed system of arteries and veins to convey the oxygen and nutrients to the tissues in a timely manner.
A system that exchange both mass and energy with surroundings is an open system . A system that doesn't exchange matter but only energy with surroundings is closed system.

A humans circulatory system is closed. Large creatures tend to have a closed system, while smaller creatures like insects and crustaceans have open circulatory systems. Closed is when there are vessels and the blood stays there. Open is when blood floats around the body. Hope it helps:)
The light bulb is a closed system: no mass transfer.
