Explanation: 

Detailed explanation-1: -Movement of blood through the heart and around the body is called circulation (say: sur-kyoo-LAY-shun), and your heart is really good at it-it takes less than 60 seconds to pump blood to every cell in your body.

Detailed explanation-2: -How long does it take blood to circulate through the body? On average, it takes about 45 seconds for blood to circulate from the heart, all around the body, and back to the heart again. An average adult’s heart beats more than 100, 000 times a day.

Detailed explanation-3: -Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body’s tissues through the aorta.

Detailed explanation-4: -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-5: -Increase cardiovascular exercise. If you smoke, quit. Drink black or green tea. If you are anemic, take iron supplements or eat iron-rich food. Dry brush your body. Decrease stress. Include more omega-3 fatty acids in your diet. Wear compression socks and elevate your legs. 27-Oct-2020
