Hematic System
The heart, blood vessels and blood constitute the main components of this
closed-loop system with the heart as its central pump.
The part of the hematic system that delivers blood to and from the lungs is
known as the pulmonary circulation, and the flow of blood throughout the rest of
the body is administered by the systemic circulation. The hematic system plays
an integral role in the removal of waste products associated with metabolism and
the transportation of gases (oxygen and carbon dioxide), chemical substances
(e.g. hormones, nutrients, salts), and cells that defend the body. Additionally, this
system helps regulate the body’s fluid and electrolyte balance, pH and body
temperature, and helps protect the body from infection and loss of blood by the
action of clotting.
As noted in Chapter 2, the hematic system plays an important role in wound
repair and healing. In the early stages of wound healing angiogenesis, the
formation of capillary-sized microvessels ensure the delivery of blood-borne
cells, nutrients and oxygen to areas undergoing remodeling.
