Answer 2

Hormones 'X' is secreted during stress condition and acts on organ 'Y' to increase its rate.

Here:

• X => Adrenaline (Catecholamines)

• Y => Heart (Cardiac Effect)

During stress conditions (like flight, fight and fright) , the adrenal gland releases catecholamines. These are a group of hormones released from the adrenal medulla and helps to to withstand the stressful condition.

• Adrenaline (or Nor-Adrenaline) acts on the beta receptors of the heart and increases the heart rate.

• Increased heart rate results in higher stroke volume and cardiac output result in higher oxygen supply to the muscles of the body.

• This helps to counteract the stressful condition.
