What is the shortest living cell in the human body?
As for the liver, the human body’s detoxifier, its cells’ lives are quite short – an adult human liver cell has a turnover time of 300 to 500 days. Cells lining the surface of the gut, known by other methods to last for only five days, are among the shortest-lived in the whole body.
Which blood cell has the shortest lifespan?
Probably neutrophils (granulocytes) have the shortest lifespan of human cells, 4 hours or less. Neutrophils make up about 55–70% of our white blood cells. They are the part of our white blood cells that fight bacterial infections.

How many cells die a day?
In humans, as many as 1011 cells die in each adult each day and are replaced by other cells. (Indeed, the mass of cells we lose each year through normal cell death is close to our entire body weight!)

The smallest cell is Mycoplasma (PPLO-Pleuro pneumonia like organims). It is about 10 micrometer in size. The largest cells is an egg cell of ostrich.
How long can a human cell live?
The length of a cell’s life can vary. For example, white blood cells live for about thirteen days, cells in the top layer of your skin live about 30 days, red blood cells live for about 120 days, and liver cells live about 18 months.
Which cells in the body are never replaced?
