Yes, most organs stop growing once an individual reaches adulthood. However, some organs can regenerate and repair themselves throughout life, such as the liver and the skin.
liver
The Skin
Skin cells constantly regenerate to replace old, dead cells. Liver cells have the ability to regenerate and repair themselves after injury. Hair follicles continuously produce new hair strands to replace those that are shed.
The liver
No.
Time Lords regenerate because they have a injury or something is wrong, it's their way of healing themselves.
Yes, hermit crabs can regenerate arms and legs. They do this by molting, much in the way that snakes do when they shed. From there, their legs can regrow and regenerate themselves over time.
The liver
regeneration, where damaged tissues are replaced by new, healthy cells that restore normal function. This can involve cell division, migration, and differentiation to restore the structure and function of the organ. However, not all organs have the same capacity for regeneration, with some having more regenerative potential than others.
From what the information our generation has now, we can regenerate 5 parts of our bodies. From those 5 the three organs are the liver, kidneys, and the heart.
