There are different types of cells in our body. Scientists have estimated that a human body has 37 trilliones (3.72 × 10(13)) cells in total. Following is a list of different cell types we can identify.
Red blood cells
Red blood cell is a flattened cell and has a nucleus in the center. It is specialized to transport oxygen.
White blood cells
Liver cells
Muscle cells
There are three types of muscle cells. They are heart muscle cells, skeletal muscle cells and smooth muscle cells.
Skin cells
Epithelial cells
Intestinal cells
Neuron cells
Stem cells
stem cells are undifferentiated cells. They can produce new cells again and again. They divide by mitosis and produce new cells.
Lifespan of cells
Different cell types have different lifespans.
ex:-
RBC
intestinal cells
120 days
3-5 days
