Which of the following glands play an important role in the regulation of blood pressure, apart from human heart?
Text Solution
Verified by ExpertsB
• The adrenal gland (specifically the adrenal medulla) releases adrenaline (epinephrine) and noradrenaline (norepinephrine).
• These hormones increase heart rate, stroke volume, and constrict blood vessels, which raises blood pressure.
• The adrenal cortex also secretes aldosterone, which regulates sodium and water balance, indirectly affecting blood volume and blood pressure.
• Thyroid gland → controls metabolism, but not direct blood pressure regulation.
• Thymus gland → involved in immune system (T-cell maturation), no role in BP.
• Parathyroid gland → regulates calcium balance, not BP.
