The Cardiovascular System

These structures allow the heart to perform the main function of circulating blood, which is accomplished in two ways called lung and whole-body circuit. Pulmonary circulation represents deoxygenated blood that passes through the right ventricle, enters the pulmonary artery, enters the lungs, and passes through the left and right pulmonary veins back to the left ventricle of the heart (as oxygenated blood). Systemic circulation represents that oxygenated blood diffuses through the left ventricle and the aorta into the arteries and capillaries of the body and returns to the heart through the superior vena cava and inferior vena cava.

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

Many diseases affect the circulatory system. This includes cardiovascular diseases affecting the cardiovascular system and lymphatic diseases affecting the lymphatic system. A cardiologist is a medical professional specializing in heart disease and a cardiologist focuses on the operation of the heart and its surrounding area. Vascular surgeons focus on other parts of the cardiovascular system. The basic components of the human cardiovascular system are the heart, blood vessels, and blood vessels. It involves the pulmonary circulation through the "circulation" of the lungs, the blood is oxidized; and the whole body circulates and "circulation" through the rest of the body provides oxygenated blood. It also shows that the body cycle works in two parts, a large cycle and a micro cycle. The average adult blood contains 5 to 6 quarts (about 4.7 to 5.7 liters), which is about 7% of its total weight.
