Heyaa folk,
The heart is divided into four chambers consisting of two atria and two ventricles; the atria receive blood, while the ventricles pump blood. The right atrium receives blood from the superior and inferior vena cavas and the coronary sinus; blood then moves to the right ventricle where it is pumped to the lungs. You must be able to identify the four chambers of the heart. These are the right atrium, right ventricle, left atrium and left ventricle. You must also know the path followed by blood as it passes through the heart and its blood vessels. Atria (left and right)
Ventricles (left and right)
Semilunar, tricuspid and bicuspid valves. The four main blood vessels of the heart: Vena cava. Pulmonary artery. Pulmonary vein. The impulse spreads into the ventricles, causing the muscle to contract and to pump out the blood. The blood from the right ventricle goes to the lungs, and the blood from the left ventricle goes to the body. The heart has four chambers – two at the top (the atria) and two at the bottom (the ventricles).
Hope it helps u :)

HUMAN HEART :
》Human Heart is mesodermal in origin.
》It is located in the thoracic cavity between the lungs.
》It is protected by pericardium which is a double walled membrane enclosing pericardial fluid.
》Our heart consists of four chambers - two upper chambers called atria and two lower chambers called ventricles.
》A thick walled septum called the inter-ventricular septum separates the left and right ventricles.
》A thin septum called inter-atrial septum separates right and left atria.
》Atrioventricular septum separates the atria and the ventricle of the same side.
》Bicuspid Valve regulates the opening between the left atrium and left ventricle.
》Tricuspid Valve regulates the opening between the right atrium and right ventricle.
