Circulatory System (Speedy Study Guides) скачать fb2

The circulatory system consists of the veins and arteries throughout the body through which blood flows to and from the heart. Owning a reference guide to the circulatory system is a valuable tool in any first aid kit. A reference guide will allow the owner to immediately recognize the severity of an injury based entirely on where the injury occurs and by the amount of blood flowing from the wound. This knowledge will determine how a person treats the injury.
