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 ventricle wall is thicker as it needs to pump blood from the heart to other parts of the body. Ventricles have thicker wall so that they can withstand the intense pressure by the heart and pump blood all over the body parts. While auricles carry blood towards the heart and suffers reduced pressure so it has thinner wall.
