skin
heart
lungs

rewatch

Explanation:

Skin cells are constantly shed and replaced, making their growth rate relatively fast compared to cells in organs like the heart (which has limited regenerative capacity), lungs (with slower turnover in many cell types), and stomach (where cell turnover is significant but not as rapid as skin in terms of the entire organ - level cell renewal in a broad sense for this comparison).

Answer:

skin
