The following arteries and veins transport blood to and from some of the body's organs
Why Is The Left Wall Of The Heart Thicker. This is because the left ventricle pumps oxygenated blood round the entire body while the right ventricle only pumps blood to the lungs which is a much shorter distance. Hence why the left is thicker, due to needed more muscle to do so.
Why doesn't the heart skip out the right ventricle? - Quora from qph.fs.quoracdn.net
However, total failure of any of these valves can be catastrophic for the heart and for blood flow. The middle layer of the heart wall is the myocardium, which is the cardiac muscle—a layer of involuntary striated muscle tissue surrounded by a framework of collagen. Why are the walls of the aorta and the pulmonary trunk/arteries so thick compared to the venae cavae?
The walls of the left ventricle are three times as thick as the walls of the right one.
The walls of left ventricle are thicker than the right ventricle or all other chambers of heart because left ventricles require higher force to pump oxygenated blood hence, to force the blood to the whole body tissues strong and thick walls of the left ventricles are required. The heart is an inner hollow muscular organ placed within the chest and included in the pericardium. The left side of the heart has a thicker ventricular wall. The walls of the left ventricle are three times as thick as the walls of the right one.
