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 heart itself is divided into 4 parts, 2 atria (preloading portion of the heart), and 2 ventricles (working portion of the heart), with the right atrium and right ventricle only pumping blood to the lungs, and the left atrium and left ventricle being much more powerful and pumping blood to the entire body.
