How many cells each second die in a human body?

thats a crazy question,\n\nu could possibly find answer about how much skin we shed a day then work out how much epidermal skins die,\n\ninside the body.....in non-disease state nothing should die

One single drop of blood contains around a million erythrocytes, or Red Blood Cells \n and FYI, the average life span of a Red blood cell is 120 days!!!

Well, technically they can but usually only for about 6-8 minutes after death.  See, we define people as being dead when their heart stops beating, but for a few minutes if we can get their heart started again they'll be fine.  After about 8 minutes brain damage starts to occur, and I think somewhere between 15 and 30 minutes it becomes hopeless.  Those times will be a bit longer if the person is really cold though.

The average blood cell makes a round trip through the body's arteries and veins every 60 seconds, and can hit speeds of up to 10 mph. The heart pumps your five quarts of blood around your body 500 times a day.

One picosecond is 10^(-12) of a second or 0.000000000001 seconds.\n\nTo find out how many picoseconds in one second, we simply do the following calculation:\n\n1 / 0.000000000001 = 10^12 = 1000000000000\n\nIn other words, there are 10^12 picoseconds in one second.

Yes actually it is possible. Certain cells in the body only regenerate a specific # of times. Those cells tend to be what determines "natural death". Cells are capable of regenerating infinite numbers of times, and some do (like epithelial cells). If all of the cells of the body could be reprogrammed so that they didn't "count" when they regenerate, then yes it is possible to live forever. This is a question several institutions are beginning to work on, and several others have been working on since the 1970s.

Male is 77.64 years\nFemale 83.52 years\n\nAverage person breaths around 600,000,000 times in a lifetime \n(although this assumes 15 breaths/min and an average lifespan of 75 years)

i think this is becuase cells our cells wear out one by one and are not replaced by the body, and eventually all the cells die

According to the site below:\n\nThe time it takes blood to circulate in the human vascular system varies with age, body size and condition, and whether the person is resting or engaged in vigorous physical and/or emotional activity. Nevertheless, on average the blood fully circulates in the human body some seven to eight times per minute.

60 seconds per cell, 120 seconds total? are they in the same cup? Give me the answer!!!

any living thing by its interaction with the environment goes on accumulating toxins that ultimately result in death. Usually the animals with a high metabolic rate are the quicker to die, but they breed fast and can evolve faster, as there are many generations in a small time.\n\nall cells are genetically programmed to die. this time is different for different species

my dad died of lung cancer.  The cancerous cells replaced the good ones and didnt do the job of the old ones.  Cancer kills because the organs affected stop working as their working cells are replaced.

It varies with the cell you are discussing. Anywhere from less than 5 minutes to over 70 years.

Blood cells are produced from the bone marrow and they die in the spleen.

Assuming that counting starts a 5 years of age (which is not realistic) and continues for 70 years (75 is life expectancy for a male in the USA) and that each number takes one second to count (the average would be closer to 6 seconds) and 8 hour per 24 was spent sleeping, etc., then\n\n70 * 365 = 25550 days.\n25550 * 16 hours / day = 408,800 hours.\n408,800 * 60 minutes / hour = 24,528,000 seconds.\n\n24,528,000 at 1 second or 4,080,000 at 6 seconds per number.\n\nIn actual counting trials, it has been estimated that the typical person, loosing places, getting bored and having to eat and wash occasionally would be lucky to be able to count to one million during their lifetime.

Well, in human cells it's about 3 hours.  There are 3 billion base pairs in the human genome, so that's around 1 billion bp/hour (depending on temperature) for complex prokaryotic cells.
