The heart is divided into four chambers, the left atrium, the left ventricle, the right atrium, and the right ventricle. The two chambers in the upper portions of the heart are the atrium, and the two at the lower portions are the ventricles.
The two upper chambers in your heart are called the atria. One on its own is an atrium. This comes from the Latin word for an open entrance area in a house, because the atria are where the blood enters the heart after returning from either the body or the lungs.The right atrium receives blood from the body, and pumps it through the tricuspid valve into the right ventricle. The left atrium receives blood from the lungs via the pulmonary veins, and pumps it through the bicuspid valve into the left atrium.The atria have thinner walls than the ventricles, since they have to pump the blood a shorter distance than the ventricles.
No you don't have a heart inside your heart. The heart is made up of four chambers though. This is a short explanation about the heart. The heart is a very important muscle that you can't live without it. It pumps blood through your body. The heart is made up of 4 different parts that are called the chambers. The chambers are called Left atrium, Right atrium, Left ventricle and Right ventricle. The left atrium receives blood from the pulmonary-vein, and pumps it into the left-ventricle. The right atrium receives de-oxygenated blood from the superior and the inferior venae cavae and the coronary-sinus. The left ventricle receives oxygenated blood from the left-atrium via the mitral-valve, and pumps it into the aorta.
The right ventricle pumps blood to the lungs where the alveoli oxygenate the blood. Then the blood comes back through the pulmonary veins, and into the left atrium, through the valve to the ventricle, to the pulmonary artery, and to the different parts of the body.
The left ventricle, it works the hardest and needs the most muscle mass.

The parts of the heart are:: Aorta Pulmonary Artery Superior Vena Cava Left Atrium Right Atrium Left ventricle heart muscle right ventricle inferior vena cava
It is the valve that lies between the left atrium and the left ventricle in the heart.
Magically.

The type of muscle that is found in the right atrium is mainly the pectinate muscles. This is one of the four chambers of the heart.
The left atrium pumps the blood to the left ventricle. The left ventricle pumps the blood to supply the various organs and tissues in the body

Some terminology first: The upper chambers = atria (singular atrium) The lower chambers = ventricles The atria are responsible for receiving blood: the right atrium receives deoxygenated blood from the body and the left atrium receives oxygenated blood from the lungs. The atria only pump this blood into the ventricles and therefore do not need particularly thick muscular walls. The ventricles on the other hand are responsible for pumping the blood received from the atria to the body. The right ventricle pumps the deoxygenated blood it receives from the right atrium out of the heart and into the lungs. On the other hand, the left ventricle is responsible for pumping the oxygenated blood received by the left atrium to the rest of the body. It is because of the this that the walls on the side of left ventricle are the thickest. The left ventricle requires "more muscle" than the right ventricle as the distance it has to pump the blood is far greater. So, SHORT ANSWER: The walls of the lower chambers/ventricles are thicker and more muscular than the walls of the upper chambers/atria because they have to pump blood out of the heart and to the body as opposed to the atria which only receive blood from the body and then pump into the ventricles.
The left ventricle, it works the hardest and needs the most muscle mass.
The heart is composed of cardiac muscle, a special type of striated muscle. It contains valves lined with endocardium tissue. There are four chambers, two on the right and two on the left, where the entry chambers are the atria (right atrium, left atrium) previously known as auricles, and the pumping chambers are the ventricles.
