there are four chambers in the heart. two are atriums and two are ventricles
....INTRODUCTION: The heart is a powerful muscular organ that can pump 10,000 liters of blood daily.It is a 4 chambered muscular structure.The upper thin walled collecting chambers are called the atria.The lower thick walled pumping chambers are called the ventricles.
One of the two thin-walled chambers that receive blood into the heart is the atrium. The right atrium collects deoxygenated blood from the body through the vena cavae, while the left atrium receives oxygenated blood from the lungs via the pulmonary veins. These chambers play a crucial role in the heart's function by ensuring proper blood flow to the ventricles for circulation.
