Question

Choose the correct answer from the alternatives given.
The muscular wall that divides the heart is called:

• A. cardial wall
• B. hyoglossus
• C. trapezius
• D. septum

Answer 1

The correct option is D septum

The septum is that muscular wall that separates the right and left sides of the heart and prevents blood from flowing from the right to the left ventricle or vice versa during contraction. This helps to prevent the deoxygenated blood in the right ventricle mixing with the oxygenated blood in the left ventricle. It also helps maintain the shape and rigidity of the heart and provides strength to the walls of the heart.

So, the correct option is 'Septum'.
