Answer 1

Hint: Hormones are the chemical messengers that are secreted directly into the blood, which carries them to organs and tissues of the body to exert their functions. There are many types of hormones that act on different aspects of bodily functions and processes.

Complete step by step answer: There are several glands in our body that secrete hormones that are crucial for growth, development, reproduction, etc. Different hormones affect the body shape differently. This list and functions of significant hormones. Adrenaline hormone in the adrenal gland and some of the neurons of the Central nervous system are secreted in the medulla. It is also known as an emergency hormone because it initiates the rapid response that makes the person believe and react to stress rapidly. It raises the rate of metabolism, dilating blood vessels to the core and brain. During stressful circumstances, adrenaline releases rapidly into the blood, sending impulses to the organs to generate a particular reaction.

Additional Information:
There are basically two types of hormones which are produced by the body.
-Peptide Hormone: They are composed of amino acids and are soluble in water. They are unable to pass through the cell membrane as it contains a phospholipid bilayer that stop any fat insoluble molecule for diffusing in the cell
-Steroid hormone: They are fat soluble and are able to pass through a cell membrane.

Note: Epinephrine is a very fast acting hormone that prepares our body for emergency action also called the fight or flight reflex. It speeds up our breathing and heart rate and diverts extra blood to the muscles.
