Final answer:
When cells from distinct organs are mixed, several factors contribute to their lifespan, including cell type, external factors, and the process of hemopoiesis or hematopoiesis.
Step-by-step explanation:
When cells from distinct organs are mixed after a couple of days, several factors come into play. Firstly, different types of cells have different lifespans. For example, muscle and nerve cells have a lifetime lifespan, while adipose cells can live for years, and liver cells for a year. Secondly, external factors such as internal and external functions also impact cell longevity. Lastly, the process of hemopoiesis or hematopoiesis, which is the production of new blood cells, occurs in various tissues of the body before and after birth.
