During my previous two posts viewers have asked about grading either because they have had difficulty with it or because they want to know how to select PCGS- or NGC-gradeworthy coins. Each denomination requires different skills. The Morgan dollar ranks among the easiest to grade because of its generous fields.
Over 1,500 Gallons of Blood Pumped Daily The heart is a powerful muscle that beats without stopping throughout a lifetime. It pumps about 55-80 ml (1/3 cup) of blood with each beat for adults and around 25-85 ml per beat for children. An adult heart pumps about 6,000-7,500 liters (1,500-2,000 gallons) of blood daily.
Blood takes less time to circulate when you are active or exercising, as your heart rate decreases when you are resting. The healthy adult heart beats approximately 65 to 75 beats per minute. With each beat, the heart pumps an average of 60 to 70 milliliters of blood, or about five liters per minute.The American Heart Association points out that based on an average of 100,000 beats each day, the heart pumps out 2,000 gallons of blood.t takes the heart less than one minute to pump blood to every cell in the body. In fact, six quarts of blood can fully circulate throughout the body at least three times within that minute. That totals thousands of round trips each day.
