Cómo mantenemos el equilibrio (primera parte)

The video discusses the human sense of balance, highlighting the challenges of walking upright from birth. It explains how balance is maintained through specialized organs in the inner ear, specifically the semicircular ducts, which detect head movements. These ducts contain liquid that moves and bends microscopic hair cells, sending signals to the brain. The video also covers how these structures allow us to perceive movement in three dimensions, emphasizing that balance is not solely reliant on the ears.
