EVERYDAY SCIENCE

Detailed explanation-1: -Each day, your heart beats around 100, 000 times. This continuously pumps about five litres (eight pints) of blood around your body through a network of blood vessels called your circulatory system. This blood delivers oxygen and nutrients to all parts of your body to help your organs and muscles work properly.

Detailed explanation-2: -Your body has about 5.6 liters (6 quarts) of blood. This 5.6 liters of blood circulates through the body three times every minute. In one day, the blood travels a total of 19, 000 km (12, 000 miles)-that’s four times the distance across the US from coast to coast.

Detailed explanation-3: -The heart is an amazing organ. It pumps oxygen and nutrient-rich blood throughout your body to sustain life. This fist-sized powerhouse beats (expands and contracts) 100, 000 times per day, pumping five or six quarts of blood each minute, or about 2, 000 gallons per day.

Detailed explanation-4: -In a normal healthy adult, the heart beats 60-100 times in a minute. With each beat, the heart pumps 70 millilitres of blood out of the heart. It can move 5 to 7 litres of blood in one minute and 7600 litres per day.

Detailed explanation-5: -Normal Output. It’s different for different people, depending on their size. Usually, an adult heart pumps about 5 liters of blood per minute at rest. But when you run or exercise, your heart may pump 3-4 times that much to make sure your body gets enough oxygen and fuel.
