Q. No. 3: How does our body
respond when adrenaline is secreted into the blood?
Ans: When someone is in danger
or in emergency then adrenal gland secrete adrenaline hormone. It is secreted
directly into the blood and is transported to different parts of the body. It
speeds up the heartbeat and hence supplies more oxygen to the muscles. This
results in increasing breathing rate and blood pressure which enable them to
fight with such urgent situation.
