How Does Blood Flow Through The Heart And Lungs?

how does blood flow through the heart step by step?

Regarding this, how does blood flow through the heart step by step? Blood flows through your heart and lungs in four steps:

  1. The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle through the tricuspid valve.

What is the correct order of the flow of blood?

SA node (sinoatrial node) – known as the heart’s natural pacemaker. The impulse starts in a small bundle of specialized cells located in the right atrium, called the SA node.
