There are many section in the heart, starting with:
The Superior Vena Cava, where de-oxygenated blood flows in from the body. From there the blood flows into the Right Atrium, through the Tricuspid Valve and into the Right Ventricle. After the blood is in the Right Ventricle, the blood flows out of the heart through the Inferior Vena Cava and in to the lungs, where it can be oxygenated. Once oxygenated, the blood flows back into the heart through the Pulmonary Artery. From the Pulmonary Artery the blood flows into the Left Atrium, through the Mitral Valve and into the Left Ventricle. From there the blood flows through the Pulmonary Valve to the Aorta and out into the body. The process then starts over from there.
The four sections of the human heart are the left atrium, right atrium, left ventricle, and right ventricle.
chambers
Atrium
The term for the 4 sections of the heart muscle is the cardiac muscle.
In your heart, the top two hollow sections are called atrium and the lower two are ventricles.
veins and arteries
veins and arteries
This controlled destruction of small sections of heart muscle actually kills the nerve cells causing the irregular heartbeat, stopping the nerve signals that are passing through this section of the heart.
precisly in the middle, the heart looks like three black sections from the outside. therefore three chambered
Sections of the lungs are called lobes. The right lung has 3 lobes and the left lung has two, which allows room for the heart.
A worm does not have any part or section of a human heart.Only humans have parts and sections of a human heart.
The American Heart & Stroke Foundation is a very common website that people use for information about their heart. There are FAQs sections and you can read about various heart conditions.
