The Heart
Ventricles: These are final area the blood is transferred to before leaving the heart, the ventricles are covered in myocardium as the myocardium contracts to pump the blood out of the ventricles. The aorta: is the largest single blood vessel in the body. It is approximately the diameter of your thumb. This vessel carries oxygen-rich blood from the left ventricle to the various parts of the body. via the left and right subclavian arteries, and the left and right common carotid arteries The superior vena cava: is one of the two main veins bringing deoxygenated blood from the body to the heart.Veins from the head and upper body feed into the superior vena cava, which empties into the right atrium of the heart. The inferior vena cava: is one of the two main veins bringing de-oxygenated blood from the body to the heart. Veins from the legs and lower torso feed into the inferior vena cava, which empties into the right atrium of the heart. The Atria: receive oxygenated blood from the lungs and the body As the contraction triggered by the senatorial node progresses through the atria, the blood passes through the mitral valve into the left ventricle. The pulmonary arteries: are the vessels transporting de-oxygenated blood from the right ventricle to the lungs. vessels carrying blood away from the heart. The pulmonary veins: are the vessels transporting oxygen-rich blood from the lungs to the left atrium. they are vessels carrying blood to the heart. The chordae tendineae: are string-like and are sometimes referred to as "heart strings." They connect the heart muscles to the valves. The tricuspid valve: separates the right atrium from the right ventricle. It opens to allow the de-oxygenated blood collected in the right atrium to flow into the right ventricle. The mitral valve: (bicuspid valve) separates the left atrium from the left ventricle. It opens to allow the oxygenated blood collected in the left atrium to flow into the left ventricle. The pulmonary...
