Which human body system has the longest network?
Quick Answer
The blood vessels form the longest network in the human body. If laid end to end, they would stretch for about 100,000 kilometres.
The Full Story
The circulatory system contains the longest continuous network in the human body: the blood vessels. Across arteries, veins, and capillaries, this network is often estimated at about 100,000 kilometres in adults. It delivers oxygen and nutrients to tissues and carries away waste products. The immense length comes from the tiny capillaries, which branch throughout nearly every tissue in the body.
