The heart beats 70 times a minute, with each beat the heart pumps 60 to 90 mililiters (2 to 3 ounces) of blood out of the heart. It can move 5 to 7 liters of blood in one minute and 7600 liters (2000 gallons) per day. In a lifetime, it beats over 2.5 billion times and pumps over 200 million liters of blood. Infants have slightly faster heart beat than an average person, their heart beats 120 times per minute.

Confidence votes 15. nucleoli form ribosomes. The ribosomes are known to produce or manufacture proteins and therefore, nucleolus plays an indirect role in protein synthesis. Out of the total production of RNA that takes place in the cells, nucleolus is involved in 50% of the RNA synthesis.This functionality of nucleolus is attributed to hundreds of r-genes.he ribosomes are known to produce or manufacture proteins and therefore, nucleolus plays an indirect role in protein synthesis.
