More than you can imagine. Over trillions
Neurons in the brain and spinal cord are cells in the body that are never replaced.
yes, in every part of your body you have you have skin cells
On average, most cells in the human body are replaced every 7-10 years.
Brain cells are not typically replaced in the human body. The majority of brain cells are formed before birth and are not regenerated throughout life.
Skin cells on the body typically live for about 2-4 weeks before they are shed and replaced.
Muscle cells,Skin cells, and white blood cells.
2,000,000,000
red blood cells are replaced ever 120 days, so therefore are replaced 3 times a year
It all depends on which cells. Some are not replaced. These are mostly nerve cells such as found in the brain. Other cells constantly die and are shed and replaced from tissues below them. An example of this are your skin cells.
There are about 2 000 000 000 of your body cells are replaced each day
Almost every cell in the human body is replaced every few years through the process of cell division and renewal. This process is called cell turnover, where old or damaged cells are constantly being replaced by new cells to maintain the integrity and functionality of tissues and organs.
If by 'replaced' you mean, can the body grow new ones like with blood and tissue cells, then no, not at present. There is some promising research being done with stem-cell therapies, but they're a long way from being able to effectively regrow nerve tissue.
