Normal Heart

What is Normal Heart?

The heart is the primary organ of the circulatory system. It is a muscular organ that pumps blood through vessels to deliver oxygen to the body. It is divided into 4 chambers:

  • Right Atrium
  • Left Atrium
  • Right Ventricle
  • Left Ventricle

The chambers on the right side of the heart receive oxygen-poor blood from the veins, often referred to as “blue” blood. The chambers on the left side pump oxygen-rich, “red” blood out of the heart to the rest of the body.

Blood flows through the chambers through valves that act as one-way doors to direct blood flow. 

  • Tricuspid Valve
  • Pulmonary Valve
  • Mitral Valve
  • Aortic Valve

The heart has a muscular wall called the septum that separates the right and left sides of the heart. In a normal heart, this helps to keep the "blue" and "red" blood separate so they don't mix.
