Hormones that regulate blood pressure are produced in which organ?

The kidneys are vital in regulating blood pressure due to their role in managing fluid balance and electrolyte levels in the body. They produce hormones such as renin, which is part of the renin-angiotensin-aldosterone system (RAAS). When blood pressure drops, the kidneys release renin, which initiates a series of reactions leading to the formation of angiotensin II, a potent vasoconstrictor that increases blood pressure. Additionally, angiotensin II stimulates the release of aldosterone from the adrenal glands, promoting sodium and water reabsorption in the kidneys, which further raises blood pressure. This hormonal regulation is crucial for maintaining homeostasis and ensuring that blood pressure remains within a healthy range, especially during times of stress or blood loss.
