Detailed explanation-1: -The right atrium and left atrium are separated by a wall of tissue called the atrial septum. The two lower chambers are called the ventricles, and are separated into the right and left ventricle by the ventricular septum. The ventricles have thicker walls and pump blood to the lungs and body.

Detailed explanation-2: -The four chambers of the heart Your heart has a right and left side separated by a wall called the septum. On each side of the wall, there is a small collecting chamber called an ‘atrium’, which leads into a large pumping chamber called a ‘ventricle’.

Detailed explanation-3: -Your heart has 4 chambers. The upper chambers are called the left and right atria and the lower chambers are called the left and right ventricles. A wall of muscle called the septum separates the left and right atria and the left and right ventricles.

Detailed explanation-4: -The left and the right side of the heart is separated by a wall called septum. The partition between the chambers helps to avoid the mixing up of blood rich in oxygen with blood rich in carbon dioxide.

Detailed explanation-5: -Structure of the Heart The heart has four chambers: two upper chambers call the right and left atrium and two lower chambers called the right and left ventricle. There is a wall between the two atria called the atrial septum. There is another wall between the two ventricles, and it is called the ventricular septum.
