Circulatory system

The circulatory system is a linked collection of veins, vesicles, muscles, and arteries which as a whole transports blood rich with oxygen, chemical energy, amino acids, and other necessary nutrients throughout a creature's body.[1]

## History[edit]

One of the first men to give a nearly accurate description of the human circulatory system was Michael Servetus, during the early sixteenth century, A.D.
