How many chambers does the heart have?

The heart has four chambers, which consist of two atria and two ventricles. The right atrium receives deoxygenated blood from the body and pumps it into the right ventricle, which then sends this blood to the lungs for oxygenation. Simultaneously, the left atrium collects oxygenated blood from the lungs and delivers it to the left ventricle. The left ventricle is the strongest chamber, pumping oxygen-rich blood throughout the body. This four-chamber structure ensures an efficient separation of oxygenated and deoxygenated blood, allowing for effective circulation and optimal respiratory function. Understanding the heart's anatomy is crucial for interpreting EKGs and recognizing various cardiac conditions.
