✔SEPTUM divides the heart into atrium and ventricles.

It separates oxygenated blood from deoxygenated blood and thus prevents mixing of blood.

Answer 2

The heart consists of four chambers: two smaller atria at the top (the base) and two larger ventricles at the apex. A band of fibrous tissue separates the atria from the ventricles and seats the four cardiac valves. A muscular septum separates the right from left atrium and the right from left ventricle.
