According to my research the average 10 year old has opproximently 2 brain cells. The reason is they don't ack natural and behave strangley. They should start to get dumber through their teen years till about 24. At 24 they can normally understand more about the world and why at 10 they had w brain cells.
The number of muscles in a sixteen year old girl is the same as in any other person, which is around 650-840 muscles in the human body. These muscles are distributed throughout the body and are responsible for movement, stability, and other functions.
billions. The exact number cannot be known. We can estimate that because the nervous system makes up about 5% of the human body, and the human body contains anywhere from 10 - 100 trillion cells, that about 0.5 - 5 trillion are nerve cells.
The epidermis is a very large area of skin that is made of dead skin cells. Scientists estimate that the human body is made up of around 10 trillion cells in total. Your skin makes up about 16 percent of your body weight, which means you have roughly 1.6 trillion skin cells Of course, this estimate can vary tremendously according to a person's size. The important thing is that you have a lot of skin cells. Of those billions of skin cells, between 30,000 and 40,000 of them fall off every hour. Over a 24-hour period, you lose almost a million skin cells [source: Boston Globe]. Where do they all go? The dust that collects on your tables, TV, windowsills and on those picture frames that are so hard to get clean is made mostly from dead human skin cells. In other words, your house is filled with former bits of yourself. In one year, you'll shed more than 8 pounds (3.6 kilograms) of dead skin. It gets even grosser: Your house is also filled with trillions of microscopic life forms called dust mites that eat your old dead skin. Imagine the depth of dead cells you would have to walk through without them!
Brain cell do not divide in later life. Cardiac muscle divides itself less than 1% each year in humans.
Sperm cells do not age in the same way that other cells in the body do. The production of sperm cells begins at puberty and continues throughout a male's life. The structure and function of sperm cells remain relatively consistent regardless of a person's age.
The levels of organization and function in a human body is equal to the order and amount in base pairs of 25.67% of your DNA, and the section of gene traits that have mutated in the process of a point in time within a year.

Stem cells currently have no use in the medical industry but around the year 2025 scientists are hoping to be able to master the art of being able to turn stem cells to a human's own cells which could cure cancer and many other diseases.
It is approximated that human beings shed at least 30000 skin cells every year. This is equivalent to 8 pounds of skin cells annually.

Blood has an important role in the body. As blood passes by cells, it deposits oxygen rich nutrients and carries away the cells waste.
The human body has about 8 pints of blood on average.
to many to count
1 chimp year = 2 human years
Liver cells divide about once a year, and neurons (nerve cells) never divide once we are born (and when they are mature).
About 30 trillion.
The average human consumes 24 pounds of cand a year...
