Is your circulatory system open or closed?
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:)
What is true about chemical reactions in a closed system?
In a closed system, matter cannot enter or leave the system, but energy can still be exchanged with the surroundings. Chemical reactions in a closed system will reach equilibrium, where the rates of the forward and reverse reactions are equal and the concentrations of reactants and products remain constant. The total amount of matter in the system will not change during a reaction in a closed system.
Is the Hawk circulatory system open or closed?

What is closed system?
1. A closed system is a system which is isolated so that it cannot exchange matter or energy with its surroundings.
What is the difference between an Open vs. a Closed System in a chemical reaction?
In a closed system, matter does not change. In an open system there is a free flow of matter in and out so you can exchange particles, lose particles or gain particles from the outside of the system
