How many chambers does the heart have?

The heart has four chambers, which is a key concept in understanding human anatomy and physiology. These chambers consist of two atria (the upper chambers) and two ventricles (the lower chambers). The atria receive blood entering the heart, with the right atrium receiving deoxygenated blood from the body and the left atrium receiving oxygenated blood from the lungs. The ventricles then pump blood out of the heart; the right ventricle sends deoxygenated blood to the lungs for oxygenation, while the left ventricle pumps oxygen-rich blood to the rest of the body.

Understanding the structure of the heart is essential for comprehending how blood circulation works, including the roles of the different chambers in maintaining efficient blood flow and oxygen delivery throughout the body. This knowledge is also useful in various fields, including yoga practice, where understanding the cardiovascular system can enhance the practice's physical and energetic aspects.
