Detailed explanation-1: -The hardest working muscle is the heart. It pumps out 2 ounces (71 grams) of blood at every heartbeat. Daily the heart pumps at least 2, 500 gallons (9, 450 liters) of blood. The heart has the ability to beat over 3 billion times in a person’s life.
Detailed explanation-2: -The left ventricle is the largest and strongest chamber in your heart. The left ventricle’s chamber walls are only about a half-inch thick, but they have enough force to push blood through the aortic valve and into your body.
Detailed explanation-3: -Second strongest muscle: Masseter is the second strongest muscle in the human body.
Detailed explanation-4: -No, the tongue is not the strongest muscle of the body. The tongue is made up entirely of muscle. It is made up of eight different muscles that intertwine with each other creating a very flexible matrix. The masseter is the strongest muscle in the body that is responsible for lifting up the jaw.
