26 wrz 2022 · Anti-diuretic hormone (ADH) or vasopressin is important in regulating blood volume and electrolyte levels, especially sodium. Its primary function is to regulate serum osmolarity. The ADH levels are lower when the osmolality is below 280 mOsm/kg in a normal individual. This results in water excretion.
The endocrine system comprises glands and tissues that secrete hormones to regulate and coordinate vital functions in the body. Endocrine glands differ from exocrine glands by releasing their secretions directly into the bloodstream, rather than a central duct.
The endocrine system is driven by hormones released into the bloodstream in order to regulate other, distant organs (see Figure 1.3). These hormones are chemical messages that are decoded by specific recognition sites, or receptors, located in the target cells.
endocrine regulation. The end-product or negative regulator can either be an inor-ganic ion or a metabolite (e.g., calcium for PTH) or a hormonal product in the endocrine cascade (e.g., thyroid hormone for TSH, IGF-1 for GH, cortisol for ACTH), since many hormones are linked to the hypothalamus-pituitary (HP)-axis.
The actions of hormones in the endocrine system allow for the exquisite regulation of energy production and metabolism, somatic growth and development, reproduction, and responses to internal and external stimuli.
