Anatomy, Blood Circulation and How Heart Works

How Heart Works 

In this article we will share information about heart, how to work, anatomy, and so forth. The heart is simply a pump that consists of two parts, the mechanical and the other is electrical parts. Both parts are interrelated, since the mechanical function of the heart itself is governed by the electrical system in the heart. The electrical system can actually be influenced by neurotransmitters of the brain (or artificial pacemaker). But since we are only talking about the heart of today, we will only focus on the ability of the system to the heart.

 Heart Anatomy

 
The heart is a pump that has four chambers. Two booths are located in the so-called Atrium, and the two below are called ventricles. The heart can also be divided into two parts, namely the right of the charge pump blood to the lungs, and the left in charge of pumping blood throughout the human body. Atria and ventricles will each be separated by a valve, while the right and left heart will be separated by a partition called the septum. Heart valve function, especially the blood that has been pumped back did not get into it again.

Blood Circulation in Heart

The road begins in blood through heart the superior vena cava. Then the blood enters the right atrium, flows through the tricuspid valve into the right ventricle. From there the blood travels through the pulmonic valve went into the pulmonary artery, and then enters the lungs. After doing blood gas exchange in the lungs, blood returning to the heart through the pulmonary vein and into the left atrium. Blood then flows through the mitral valve into the left ventricle which is the most powerful heart chambers. From there, the blood is pumped through the aortic valve and into the aorta and out into the rest of the body.
