The Role of ADH in Negative Feedback Mechanisms

The video explains how the hormone ADH, released by the pituitary gland, regulates water concentration in the blood through a negative feedback mechanism. When water levels are high, less ADH is released, reducing water reabsorption in the kidneys. Conversely, when water levels are low, more ADH is released, increasing water reabsorption. This process helps maintain homeostasis by keeping water concentration at normal levels.

Describe the process that occurs when the water concentration in the blood is too low.

Explain how the kidney tubules react when more ADH is present in the bloodstream.
