The heart has four chambers, the right and left atriums and the right and left ventricles. The artiums fill with the blood arriving from the body. The ventricles pump the blood out. The right ventricle pumps de-oxygenated blood to the lungs while the left ventricle pumps oxygenated blood to the rest of the body.

∙ 12y agoThe human heart has four chambers. The upper two chambers, the right and left atria, are receiving chambers for blood. The atria are sometimes known as auricles. They collect blood that pours in from veins blood vessels that return blood to the heart. The heart's lower two chambers, the right and left ventricles, are the powerful pumping chambers. The ventricles propel blood into arteries, blood vessels that carry blood away from the heart.
Four valves within the heart prevent blood from flowing backward in the heart. The valves open easily in the direction of blood flow, but when blood pushes against the valves in the opposite direction, the valves close. Two valves, known as atrioventricular valves, are located between the atria and ventricles. The right atrioventricular valve is formed from three flaps of tissue and is called the tricuspid valve. The left atrioventricular valve has two flaps and is called the bicuspid or mitral valve. The other two heart valves are located between the ventricles and arteries. They are called semilunar valves because they each consist of three half-moon-shaped flaps of tissue. The right semilunar valve, between the right ventricle and pulmonary artery, is also called the pulmonary valve. The left semilunar valve, between the left ventricle and aorta, is also called the aortic valve.

Mississippi's purple heart winners?
The Purple Heart is our nation's FIRST medal; and General Washington did state, "...that it's amazing what men will do for a simple piece of purple cloth..."(purple cloth was the first purple heart medal). States "might" not publish a list of Purple Heart recipients for public review, and any list you might find on the web are most likely "voluntarily submitted" names. Which means that a lot of men who don't use the computer won't have their names listed.
