The separation of the right side and left side of human heart is useful to keep oxygenated blood from mixing with deoxygenated blood.
Thus, the correct answer is option (a).
- A wall of muscle called the septum separates the left and right atria and the left and right ventricles.
- These are referred to as the atrial and ventricular septum.
- Each half consists of a larger pumping chamber (ventricle) and a smaller filling chamber (atrium).
Few facts on heart chamber:-
From the right side the blood is pumped to the lungs (pulmonary circulation).
The left ventricle is the strongest because it has to pump blood out to the entire body.
The heart is in the chest, slightly left of center.
The left ventricle, a powerful muscular chamber that pumps the blood back out to your body.
