EVERYTHING YOU EVER WANTED TO KNOW ABOUT HEARTS
Anatomy of the Heart The heart is a hollow muscle. It is located on the left side of your chest, about the size of your clenched fist It is divided into four sections called chambers Two chambers are on the left and right side. Each side has an upper and lower chamber.
Chambers of the Heart The right upper receives blood from the body. The right lower pumps blood to the lungs. The left upper receives blood from the lungs. The left lower pumps blood to the rest of the body.
Valves Valves are flaps of tissue that stop blood flowing backwards There are two kinds of valves in the heart. The first kind is the massive valves between the atria and the ventricles, the atrio-ventricular valves, (AV valves) that prevent blood in the ventricles from flowing back into the atria. The flaps of these valves are attached to the walls of the ventricles by tendons chordae tendinae
Valves The second kind of valve is pocket shaped flaps of tissue called the semilunar (half moon) valves They are called the pulmonary and aortic valves and found at the entrance of the pulmonary artery and aorta respectively
Whats the Lub Dub? The first heart sound (lub) is caused by the acceleration and deceleration of blood and a vibration of the heart at the time of the closure of the tricuspid and mitral valves. The second heart sound (dub) is caused by the same acceleration and deceleration of blood and vibrations at the time of closure of the pulmonic and aortic valves.
