The total volume of blood pumped through the heart per day is:
70 x 70 x 60  x 24 = 7 056 000 ( ml )
7 056 000 ml = 7 056 l => It closest to 7000 l so we choose D
Answer: D. 7000 l

21 tháng 7 2021

In 1 minute, it can pumped:

70 x 70 = 4900 ( ml )

In 1 hour, it can pumped:

1 hour : 60 (minutes)

4900 x 60 = 294 000 ( ml )

In 1 day, it can pumped:

1 day = 24 hour

294 000 x 24 = 7056000 ( ml )

7056000 ml = 7056 l

Answer: 7056 l

Blood donation: The most valued service to mankind

Millions of people owe their lives to people whom they will never know or meet in their lifetime. They are none other than those people, who have donated their blood freely and without any reward - voluntary blood donors. Voluntary unpaid donors are the foundation of a safe blood supply which saves millions of human beings from the death.

Nothing is comparable to the preciousness of human blood. In spite of the rapid and remarkable conquests of medical science today, there is no laboratory that manufactures blood. It is only in human beings that human blood is made and circulated. For those who require blood for saving their lives, sharing from other people is the only means. Therefore, voluntary donation is the only way of accumulating blood at safe storage to meet emergency requirements for saving lives. Blood is required for treatment of accidental injuries, burns... In times of accidental injuries that shed huge amounts of blood and also in various types of surgical operations for medical treatments, we require blood for transfusion. Unavailability of blood may cost lives. Therefore, importance of blood donation is tremendous. This is the greatest gift one can give to the humans. Voluntary blood donors are saviors of mankind. If someone really loves oneself and other fellow beings, the only way to express it is to donate blood voluntarily.

Blood donation is harmless and safe in the body. Rather, it is a social responsibility. The donor is donating for it as it will be used in saving lives of his fellow beings. He himself may use the same during his own need. So, today's donor may be tomorrow's recipient. Without their humane gifts of noble donors, that also from the heart, many lives might have lost for want of blood. Therefore, the most generous and biggest ever contribution to mankind is blood donation.
