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.
There are a couple of primary differences between the atria and ventricles. The heart has four chambers. Atria make up the top chambers of the heart whereas ventricles make up the bottom chambers. This means that there are atrium and ventricle on both, right and left sides of the heart. The right part of the heart receives unoxygenized (impure) blood and sends it from ventricles to the atria.
