Question

ooo cricket 12:51 2. When the body is dehydrated, the mouth and throat become dry. When receptors in the mouth and throat detect dryness, they send nerve impulses to the brain. In response to the signal from the dry mouth, the brain sends nerve impulses that create the sensation of thirst. The brain also sends nerve impulses to the skeletal muscles that allow the body to seek water and to drink. After drinking enough water, the mouth and throat are no longer dry and the receptors stop sending nerve impulses to the brain. The person is no longer dehydrated or thirsty and stops drinking water.
