Question

Explain the structure of a heart for class 7th

Answer 1

Hey friend,

Here is the answer :-

➡ The human heart is divided into 2 parts - Left and Right. There is a separation in between the Right and the Left part of the heart known as Septum which prevents the oxygenated blood from mixing with the de oxygenated blood.

The upper chambers are called as Auricles while the lower chambers are called as Ventricles.

There are total 4 chambers -

1. Right Auricle
2. Right Ventricle
3. Left Auricle
4. Left Ventricle

The left part of the heart receives oxygenated blood through Pulmonary veins from the lungs and pumps it to different part of the body.

While the right part of the heart receives de oxygenated blood from different parts of the body through the Superior Vena cava and the blood is sent to the heart for purification through the Pulmonary Artery.

I hope this will help you....
