Septum is the part of your nose between each nostril lol The pericardium is a part that protects the heart from infections, prevents excessive dilation of the heart, and it also lubricates the heart.

Oh wow, I am so wrong! Lol Your answer is septum!!! The interventricular septum seperates the two lower chambers of the heart, which prevents the blood from mixing. Lol brain fart!
