Anemia - The kidneys pick up on hypoxia and increase the levels of red blood cells to better oxygenate. If the kidneys are no longer functioning properly, they will not have this negative feedback.

Acromegaly is a disorder caused by overproduction of which hormone?

Growth Hormone

The additive effects of growth hormone (GH) and glucocorticoids illustrate the _________?

In order to make the heart more responsive to epinephrine, thyroid hormone must also act on the heart muscles, this hormonal coordination is referred to as a(n) _______ effect.

permissive

Which hormone is responsible for the stimulation of red blood cell formation in the bone marrow?

Erythropoietin - it is released by the kidneys in response to low oxygen levels in the kidney tissues, EPO for short, stimulates the red bone marrow to produce red blood cells.

Following blood donation, which hormone is needed to stimulate red blood cell formation?

Erythropoietin - the kidneys release this hormone when hypoxia is detected, this increases the number of RBCs to increase the oxygen content of the blood.

What phase of the general adaptation syndrome or stress response is dominated by the hormone epinepherine?

The alarm phase - an immediate response to the stress occurs, the sympathetic division of the autonomic nervous system directs this response.

why do the levels of GH-RH and CRH rise during the resistance phase of the general adaptation syndrome?

The need for glucose by the nervous system is great. This happens when stress levels are increased for more than a few hours.

Alcohol is a diuretic and exerts its effect by inhibiting which hormone?

Name an intestinal hormone responsible for stimulating the gallbladder to secret bile.

The differing but complementary effects of calcitriol and parathyroid hormone on tissues involved in calcium metabolism illustrate the:

Integrative effect - The differing effects of calcitriol and parathyroid hormone on tissues involved in calcium metabolism are an example.

The hormone insulin lowers blood glucose concentration and glucagon raises it. This is an example of what type of hormone interaction?

antagonistic
