Blood is pumped by the heart through a closed circuit of
blood vessels to the body tissues, returning back to the heart. This chapter
focuses on the structure and func-tions of the blood. The blood’s functions
include trans-portation, protection by fighting foreign invaders, and clotting
to prevent bleeding. The blood is also involved in maintaining acid–base
balance, fluid and electrolyte balance, and the regulation of body temperature.
