Flowchart of Thirst Response: The thirst response is triggered by osmoreceptors detecting increased blood osmolality, stimulating the hypothalamus to promote water-seeking behavior and ADH release for water conservation in the kidneys.
Digestive Secretions Absorption of Water: Digestive secretions contain enzymes and fluids that aid digestion, while most water absorption occurs in the small intestine, with the large intestine absorbing the remainder.
