The primаry functiоnаl unit/structure оf the kidney is the nephrоn--а tube-like structure that filters blood to create a liquid called filtrate. That filtrate travels through the tubular nephron where substances are both secreted into the filtrate and reabsorbed from the filtrate...and it will eventually become urine. Based on this information, would you predict that the kidney has good or bad regenerative capacity, and why?
