The left ventricle is thickest (as it is in all four-chambered mammalian hearts) this is because it is the part of the heart that pumps blood around the whole body and so needs to be able to withstand greater pressure hence the thickness
The left ventricle, it works the hardest and needs the most muscle mass.
Another word for myocardium is the heart muscle. The myocardium is the middle and thickest layer of the heart wall.
If you look at the back wall of a fetal pig heart, you will see a vessel that is large in size in a sheep compared to the small size of the fetal pig heart. In sheep, the hemiazygous vein develops a connection to the heart through what becomes the superior vena cava.
The eye wall.
veins
The left ventricle, being responsible for pumping the blood through the systemic circulation, generates the highest pressures. For this reason, the left ventricle has the thickest muscular walls.
the heart
That would be the left ventricle, it needs to pump blood to the high pressure, high resistance systemic circuit and requires the muscle to do so, hence it is the thickest part.
Heart on a Wall was created in 1981-12.
The layers of the HEART {outermost-innermost} 1. Epicardium {This is the outer layer is also known as VISCERAL PERICARDIUM and contains fat, which helps to cushion the heart} 2. Myocardium {This middle layer is the thickest layer of the wall and is made primarily of cardiac muscle} Endocardium {This innermost layer is thin and very smooth, and stretches as the heart pumps blood}
the thinnest wall of the heart is the one supplying heart to the lungs ie : the left side. the thinnest wall of the heart is the one supplying heart to the lungs ie : the left side.
The endocardium is the innermost layer of the heart wall.
