How much time does blood take from the heart return to the heart?From Science Trivia


In early case it takes 20 seconds and it takes 60 seconds even if in slow case.


The speed that blood flows through is 50cm per second in aorta, 15cm per second in vena cava and 0.05cm per second in capillary.


Amount of the blood is 8% of the weight of male adults and 7% of female adults.


When we lose quarter of the blood, we lose consciousness and when we lose one-third, we die.
