When the kidneys sense a drop in the blood oxygen level, the adrenal gland releases erythopoietin, also commonly known as EPO. This chemical signals the bone marrow to synthesize more RBCs (Red Blood Cells)
when the kidneys sense a low oxygen level in the blood, the adrenal gland releases a hormone called Erythropoietin also commonly referred to as EPO, signaling the bone marrow to synthesize more Red Blood Cells.
GLYCOPROTEIN
Calcitonin
The hormone called as parathyroid hormone or parathormone. This hormone is secreted by parathyroid glands.
The hormone is called as calcitonin. This hormone is secreted by the parathyroid glands.
Anti-diuretic hormone (or ADH) is released by the pituitary gland to encourage the kidneys to reabsorb water.
The hormone is called as parathyroid hormone. It is secreted by the parathyroid glands.
Calcitonin
a blood test performed to determine the serum levels of a hormone secreted by the parathyroid gland in response to low blood calcium levels.
Calcitonin is released from thyroid gland in response to hypercalemia. On the other hand, parathyroid hormone- as you guessed - is from parathyroid gland in response to low levels of blood calcium. Which will cause calcium to be released from bone into blood to compensate.
The hormone called as parathyroid hormone or parathormone. This hormone is secreted by parathyroid glands.
Insulin is a peptide hormone released by the pancreas when glucose levels in the blood rise.
The hormone is called as calcitonin. This hormone is secreted by the parathyroid glands.
Endocrine reflex
Glucagon is the hormone released by the kidneys when blood sugar levels fall too low. This hormone forces the liver to break down glycogen into glucose needed by the cells.
Many reasons. Glucose levels, hormone levels, cholesterol, infections, anemia, cancer indicators, kidney function, liver function, & on and on the list goes.
The one most commonly thought of is cortisol, which is released by the adrenal glands in response to sustained high levels of stress. However, epinephrine and norepinephrine (old names are adrenaline and noradrenaline) are also stress hormones.
Insulin is secreted by the pancreas to control blood sugar levels.
Your brain, in response to various signals sent by the digestive system, blood nutrient levels, certain hormone levels, etc.
