How do camels hold their urine so long?

Camels can hold their urine for extended periods due to their highly efficient kidneys, which concentrate urine and minimize water loss. Their bodies also reabsorb water from their urine before excretion, allowing them to conserve vital fluids. Additionally, camels have adapted to their arid environments, enabling them to tolerate dehydration better than many other animals. This combination of physiological adaptations helps them survive long stretches without water.
