Some skin cells and red blood cells must replenish themselves every 10-120 days: cells lining the digestive tract replace themselves every 3 days, under ordinary conditions, many muscle cells reproduce themselves only once very few years. Liver cells have the ability to reproduce quickly. However, some brain cells once damaged, they are lost forever.

Cells are organized into tissues, systems of cells working together that perform specialized tasks (muscle cells). Tissues group to form whole organs, discrete structural units made of tissues that perform specific jobs (heart). Body system, a group of related organs that work together to perform a function (cardiovascular system).
