Concept explainers
(a)
To determine: The hormone that promote water conservation.
Introduction: The kidneys regulate water and salt balance in the body. Hormones are proteins that play vital roles in functioning of the body and to maintain homeostasis. Salt and water balance is essential to maintain homeostasis. Hormones are involved in regulating this salt and water balance.
(b)
To determine: The hormone that promote sodium conservation.
Introduction: The kidneys regulate water and salt balance in the body. Hormones are proteins that play vital roles in functioning of the body and to maintain homeostasis. Salt and water balance is essential to maintain homeostasis. Hormones are involved in regulating this salt and water balance.
(c)
To determine: The hormone that promote thirst behavior.
Introduction: The kidneys regulate water and salt balance in the body. Hormones are proteins that play vital roles in functioning of the body and to maintain homeostasis. Salt and water balance is essential to maintain homeostasis. Hormones are involved in regulating this salt and water balance.
