This depends on what is meant by "closed system". If you are doing thermodynamics, this seemingly English language phrase means systems which exchange energy in or out of the system, but not mass: no mass in / no mass out. If you really understand physics you will recognize some nonsense here, because energy has mass. But, it works for thermodynamics.
For other areas of science, a more appropriate definition is no exchange of energy of any kind, no exchange of mass of any kind, no exchange of momentum of any kind. Perhaps such a system should be called an isolated system.
HEAT
It does not exchange matter.
_____ systems allow for the exchange of materials with the outside environment.
A closed system is a system that can exchange energy (heat and work)with its surroundings, but can not exchange matter with its surrounding.A greenhouse to some extent can be thought of as a closed system exchanging heat with its surroundings.In general, a system is the part of the universe under consideration.Systems can be isolated, closed, or opened.An isolated system can not exchange energy, and can not exchange matter with its surroundings.In contrast, an opened system can exchange both energy and matter with its surroundings.
All types of systems only exchange energy within the system.
HEAT

Simple, matter.
Systems can be classified as open, closed, or isolated. Open systems exchange both matter and energy with their surroundings, closed systems only exchange energy, and isolated systems exchange neither. These classifications are based on the extent of interaction between the system and its environment.
A system that cannot exchange matter with its surroundings A system that allows energy to move in and out but not mass ~ Apex
Organisms are open systems due to the fact that they maintain a steady state. They exchange both matter and energy with their surroundings.
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.
All respiratory systems are open as the function of a respiratory system is to exchange gases with inside of the body and the external world. The term 'open' or 'closed' refers to the vascular system.
Food exchange systems were originally developed for people with Diabetes.
_____ systems allow for the exchange of materials with the outside environment.
Ludwig Bertalanffy describes two types of systems: open systems and closed systems. The open systems are systems that allow interactions between its internal elements and the environment. An open system is defined as a "system in exchange of matter with its environment, presenting import and export, building-up and breaking-down of its material components."[1] For example, living organism. Closed systems, on the other hand, are considered to be isolated from their environment. For instance, thermodynamics applies to closed systems. The idea of open systems was further developed in systems theory. For instance, open systems in systems theory encourage a non-representational and non-referential posthumanist approach that actualize complexity of reality in a non-deterministic framework.
The exchange surfaces are moist.
