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.

(October 2012). The nucleolus is contained within the cell nucleus. The nucleolus (/nuËËkliËÉµlÉs/ ; plural nucleoli /nuËËkliËÉµlaÉª/) is the largest structure in the nucleus of eukaryotic cells, where it primarily serves as the site of ribosome synthesis and assembly.
The nucleolus directs the assembly of proteins within the cell nucleus. The nucleolus is the part of the nucleus containing most of the genes that code for the synthesis of ri â¦ bosomal RNA (rRNA: the RNA molecules found in ribosomes).So rRNA is synthesized within the nucleolus.he Nucleolus is a 'nuclear organelle' inside of the eukaryotic Cell's nucleus. It's primary role is to synthesize messenger Rna which is rapidly exported, via the Nuclear Por â¦ es, to the nearly situated Ribosome peppered Rough Endoplasmic Reticulum.
