Honestly, I bite the inside of both my cheeks and the inside of my upper an lower lip. I know when Iâm doing it so itâs not like subconsciously done. I actually like doing it, weird I know. Itâs really bad cause when I pull the skin it gets near the piece in your mouth connecting your lip and teeth.
Approximately 4.5 liters of blood circulates in the body of the average human adult. How many quarts of blood does the average person have? Use the conversion equivalency 1 gallon = 3.785 liters and 4 quarts = 1 gallon.
Each microliter of blood has on average 5 million red blood cells, 7 thousand white blood cells and 300 thousand platelets. Average total blood volume is 5 L. Thus there are about 25.3 trillion (American usage) or 2.53 x 10exp13 cells in healthy human beings (this only includes circulating blood cells).
