Neurohormonal Activation

Neurohormonal activation is the body's response involving signals from the nervous system and hormones to regulate functions like blood pressure, blood volume, and heart performance. When the heart or blood vessels sense stress or reduced blood flow, this activation prompts the release of chemicals such as adrenaline, noradrenaline, and hormones like angiotensin and aldosterone. These responses aim to maintain blood pressure and supply vital organs with blood, but if persistent, they can lead to harmful effects like increased strain on the heart, fluid retention, and worsening of conditions such as heart failure.
