Explanation:

Living system can be defined as the internal systems found in living organisms and how various materials are circulated inside organisms.

Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.

Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.

Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc.

Organs can be defined as specialized body tissues united to perform specific functions in living organisms. Some examples of organs found in humans are brain, bladder, kidney, heart, intestine, eyes, lungs, liver, etc.

A liver refers to a large, essential organ that is reddish-brown in color which is used to synthesize proteins, secrete bile, and the detoxification of metabolites.

Glycogenolysis can be defined as a process which typically involves the breaking down of the primary carbohydrates (glycogen) present in liver into glucose so as to maintain blood glucose rates and provide necessary energy for living organisms.

Hence, the true statement is that liver breaks down glycogen and releases glucose to the blood.
