Answer 1

The organ is an adrenal gland and hormone are epinephrine and norepinephrine. The system that works here is the endocrine system.

Explanation:

• When you are chased by a stray dog, your brain(pituitary gland) stimulates the adrenal gland to release epinephrine and norepinephrine from the adrenal medulla.
• These hormones are also known as emergency hormones. They prepare the body during the fight, fright and flight(3F) situation.
• They act on different organs of the body creating a sense of alertness and awareness.
• For example:- They increase the heartbeat, the strength of heart contraction and the rate of respiration while you run away.
