As for the fourth part of this new article series, entitled Of Heart Disease Guide and EKG Machines, we will just continue discussing here about the heart disease by knowing first how the heart works.

Where Is Your Heart and What Does It Look Like?

On the inside, the heart is a four-chambered, hollow organ. It is divided into the left and right side by a muscular wall called the septum. The right and left sides of the heart are further divided into two top chambers called the atria, which receive blood from the veins, and two bottom chambers called ventricles, which pump blood into the arteries.

The atria and ventricles work together, contracting and relaxing to pump blood out of the heart. As blood leaves each chamber of the heart, it passes through a valve. There are four heart valves within the heart:

• Mitral valve
• Tricuspid valve
• Aortic valve
• Pulmonic valve (also called pulmonary valve)

Allow me to stop there for a moment to give a review on this yet another superb EKG machine device brand called Quinton.
