Why is ADH secreted?
It is secreted when the body senses and increase in osmolarity, like in dehydration. It creates aqua-porins in the distal tubule in the kidneys to increase water reabsorption.
Why does one feel thirstier after she or he drink soft-drinks?
Being thirsty is a brain response due to increased blood osmolarity or decreased blood volume. The human body must keep its blood osmolarity close to 300 mOsms in order to function properly. If it is increased or the blood volume is decreased the brain will release hormones such as ADH(antidiuretic hormone- to save water) and will trigger a thirst response in the brain. Soft-drinks as opposed to water, have an increased osmolarity and therefore cannot lower your blood osmolarity to the same degree as water and therefore do not relieve your thirst. Hope that helps
Does ADH release posterior pituitary?
yes ADH is realsed by posterior pituitary
What is pituitary-adrenal stimulation?
Also known as the hypothalamic-pituitary-adrenal axis, this is by which adrenal stimulation of cortisol production (by pituitary ACTH release).
Kidneys attemt to increase hemoglobin levels by the release of what?

What hormone is necessary for water to be reabsorbed in the kidney?
Anti-diuretic hormone (or ADH) is released by the pituitary gland to encourage the kidneys to reabsorb water.
How does GnRH get from the hypothalamus to the anterior pituitary and what effects does it have on the pituitary?
The hypophysial portal system carries gonadotropin-releasing hormone (GnRH) from the hypothalamus to the anterior pituitary. It stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary.
What does the posterior pituitary gland control?
ADH secretion and oxytocim release
The pituitary hormone that controls the release of glucocorticoids from the adrenal cortex is?
Adrenocorticotropic hormone (ACTH)
How the two hormones arrive in the posterior pituitary?
These hormones arrived in the posterior pituitary from the storage of hormones made by the hypothalamus of the brain for release as needed in the body.
What is the role of hormones in an adolescence's life?
As an adolescent progresses through puberty, the hypothalamus (located in the brain) begins to release hormone signals to pituitary gland. The pituitary gland will then send chemical signals to the suprarenal glands (located above the kidneys, like hats). The zona reticularis (the inner layer of the suprarenal medulla) produces androgens which are sex hormones which act upon various organs and tissues in the body. For example, in females, estrogen and progesterone will increase breast size while in males, testosterone will increase facial hair growth, increased muscle mass, deeper voice, etc.
Which neuron tells the glands to release chemicals?
