What is Heart Weight and Health Insights about?

The human heart consists of 4 chambers, with 2 atria and 2 ventricles. It weighs around 300 grams and is about the size of a closed fist. The heart is the hardest working muscle and pumps over 2,000 gallons of blood daily through the body. Heart valves located between chambers prevent backflow of blood, including the atrioventricular and semilunar valves. Each minute the heart pumps 5 liters of blood, sending oxygenated blood to the body and deoxygenated blood to the lungs with each beat.
