Document Summary
Heart is small, only about the size of clenched fist. Located between the lungs in the middle of chest, called pericardial cavity. Interior of the heart has open spaces called chambers. Upper chamber- atrium and lower chamber is called ventricle. Un oxygenated blood enters the heart through the right atrium. From there it pumps into the pulmonary artery and enters into lungs. In lungs it picks up the fresh oxygen and drops off carbon dioxide to be exhaled. Form there the blood is pumped into the left atrium and through another set of valves it is pumped into the left ventricle. Left ventricle is the most powerful pump and forces the oxygenated blood into the entire body. Mind- body connection plays major role in heart health. How one responds to everyday stress is important factor. These factors can influence behaviors such as smoking, diet, alcohol consumption and physical activity.
