Final answer:
The order from lowest to highest degree of internal organization is cell, tissue, organ, organ system, then organism, making the statement false.
Step-by-step explanation:
The statement that the parts of the human circulatory system, placed in order from highest to lowest degree of internal organization, are the organism, organ system, organ, tissue, and cell is false. The correct order from lowest to highest is: cell, tissue, organ, organ system, and organism. Specifically for the circulatory system, the cells would be the individual blood cells, the tissues would be the blood which includes these cells combined with plasma, the organs involved are primarily the heart and blood vessels, the organ system is the cardiovascular system itself which includes all circulatory components, and the organism is the entire human body relying on this system.
