Cardiovascular System

The cardiovascular system consists of the heart and blood vessels, and is the circulatory system of our body. The main function of the system is transportation, the heart is the system pump, the blood vessel is the delivery path. By using blood as a medium, the heart transports respiratory gases, nutrients, waste products, and other substances indispensable for body homeostasis. The heart is a conical organ with apices and bases of the size of the fist. It is in the mediastinum or lumen of the chest.

The cardiovascular system consists of the heart and the blood circulation system. Over the years, cardiovascular diseases (called cardiovascular diseases) have been the main focus of psychophysiological disorders due to the central role of the cardiovascular system in stress response (Everly & Lating, 2002). Heart disease is such a situation. Heart disease is the leading cause of death in the United States every year about 1/3, which is the leading cause of death in developed countries (Center for Disease Control and Prevention, 2011; Shapiro, 2005).

Hyperlipidemia affects the cardiovascular system and causes cardiovascular disease. Cardiovascular system, also known as cardiovascular system, is an organ system that promotes the supply of oxygen, carbon dioxide, nutrients to organs and tissues of the body (Stang & Story, 2005). The cardiovascular system helps fight disease and stabilize body temperature. If cholesterol forms the inflammatory region of the blood vessel, which causes a decrease in blood flow or obstruction, the system is susceptible to disease

Cardiovascular system is a broad term including cardiovascular and lymphatic system. The lymphatic system will be explained later in this chapter. The cardiovascular system consists of the heart (heart) and the blood vessels (blood vessels) necessary to transport blood. The vasculature consists of arteries, veins and capillaries. Vertebrates including most mammals (including major animals such as fish, birds, reptiles) have a closed cardiovascular system. The two major cycling pathways of invertebrates are single cycle and double cycle paths.
