The human body monitors the amount of water in the blood. When there is too little water, a message is sent to the pituitary gland causing the release of antidiuretic hormone (ADH). ADH causes the kidneys to re-absorb water from the urine so that the blood water level returns to the normal range.This is an example of:

To avoid dehydration or overhydration, proper water balance must be maintained in the body. One way that the water concentration of the body is monitored is by osmoreceptors in the hypothalamus which detect the concentrations of ions in the extracellular fluid. When a change in the concentration of ions in the blood is detected, such as during exercise, the body must respond. To do so, the hypothalamus produces antidiuretic hormone (ADH), also known as vasopressin. ADH is then transported to and released from the pituitary gland, where it travels to several areas of the body including the kidneys. ADH functions to stimulate the insertion of ‘water channels’ called aquaporins into the membranes of the kidney tubules, allowing for greater water reabsorption.If a person were to experience over hydration, what would happen to the levels of ADH secreted from the pituitary gland and the permeability of water in the kidney tubule?

The pituitary releases a hormone called ADH when the hypothalamus senses that ion concentration is high in the blood. This often occurs when someone has not had enough water to drink. What is the target organ for the ADH?

ADH tends to increase the amount of water reabsorbed by the body.Group of answer choicesTrueFalse

What is the function of antidiuretic hormone (ADH)?Multiple choice question.It decreases release of oxytocin.It decreases water retention by the kidneys.It increases heart rate.It increases water retention by the kidneys.
