Hormone produced in medulla of adrenal gland the Bbl6epuTe opuH OTBeT: a. aldosterone b. glucagon c. insulin d. adrenaline

The correct answer is d. adrenaline.<br /><br />The adrenal gland is divided into two main parts: the adrenal cortex and the adrenal medulla. The adrenal medulla is responsible for producing and secreting catecholamines, which include adrenaline (also known as epinephrine) and noradrenaline (also known as norepinephrine).<br /><br />Adrenaline is a hormone and neurotransmitter that plays a crucial role in the body's fight-or-flight response. It is released in response to stress or perceived threats and prepares the body for rapid action by increasing heart rate, blood pressure, and blood glucose levels, among other effects.<br /><br />Aldosterone, on the other hand, is a hormone produced by the adrenal cortex, not the adrenal medulla. It helps regulate blood pressure and electrolyte balance by promoting the reabsorption of sodium and water in the kidneys.<br /><br />Glucagon and insulin are hormones produced by the pancreas, not the adrenal gland. Glucagon raises blood glucose levels, while insulin lowers them.<br /><br />Therefore, the correct answer is d. adrenaline.
