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:)
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.
Hawks have a closed circulatory system, meaning that blood flows through a series of vessels and does not come into direct contact with the tissues or organs. This type of system allows for efficient nutrient and oxygen transport to the body's cells.
1. A closed system is a system which is isolated so that it cannot exchange matter or energy with its surroundings.
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
A battery-operated wrist watch is a closed system. A wind-up wrist watch is an open system.
Amphibians have closed circulatory system Closed
A fuel cell is different from a battery cell in so far as reactants are constantly supplied to a fuel cell making it an open system whereas a battery cell is a closed system that stores the reactants within it. A fuel cell works as long as fuel is supplied to it whereas a battery cell requires regular replacements.
Closed circuits work, they have all the wires connecting from the battery, the switch and the lightbulb that is needed for the electrical current to flow through the battery through the closed switch into the light bulb and back into the battery. Therefore it works.

Closed System
The light bulb is a closed system: no mass transfer.
The closed system prevented the flys in.
Yes it has a closed circulatory system
