Solution

In case of danger, emergency, or stress, adrenaline is secreted by adrenal glands in large quantities to prepare the body to face the situation. For this reason, it is also known as ‘emergency hormone’. This hormone is secreted even in normal situations, but in small quantities.

Adrenalin is secreted directly into the blood and is transported to different parts of the body. The specific tissues/organs on which this hormone acts also includes the heart.
The three effects produced by the hormone adrenaline in our body are:
It results in faster heartbeats.
It results in more supply of oxygen to the muscles.
The breathing rate also increases due to contractions of the diaphragm and rib muscles.
