1 Tennis elbow, in which a tendon on the outside of the forearm fails and begins to tear away from the bone. 2  While this injury originates near the elbow, pain may extend down the forearm. 3  Golferâs elbow, similar to tennis elbow, this injury affects the tendon on the inner side of the elbow.
The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis.
Combined with the cardiovascular system, the circulatory system helps to fight off disease, helps the body maintain a normal body temperature, and provides the right chemical balance to provide the bodyâs homeostasis, or state of balance among all its systems. The circulatory system consists of four major components: 1  The Heart: About the size of two adult hands held together, the heart rests near the center of the chest. 2  Thanks to consistent pumping, the heart keeps the circulatory system working at all times.
