It's so funny you just mentioned Maca root. I was going to google it later to see if it's safe to take during pregnancy/ttc. It is in my Amazing Grass superfood drink I purchased recently. Maybe it will help =). I know it's good for regulating hormones.
In comparison with the right ventricle, the left is both shorter in length and is transversely circular in a concave manner. It forms the lesser part of the sternocostal surface of the heart anterosuperiorly, the larger part of the diaphragmatic surface inferiorly as well as the apex of the heart.
The myocardium would then prevent the left ventricle from bursting as it pumps blood rapidly to all the organs in the body. There is a difference in the length of the left and right ventricle as well. The length of the right ventricle tends to be much shorter than the left ventricle.
