The circulatory system includes which description?

Explanation:
The circulatory system is the network that moves blood through the body, using the heart as the muscular pump and the blood vessels as the channels that ferry it everywhere. Its main job is transport—delivering oxygen and nutrients to tissues and carrying carbon dioxide and other wastes away for removal. It isn’t about moving air—that’s the job of the respiratory system. It isn’t a single organ that filters blood; while blood passes through organs like the kidneys to be filtered, the description of the circulatory system itself is the system that moves blood throughout the body.
