In Biology 12 in Unit 4, we learned about different types of glands and hormones. Hormones are a group of substances that are produced and secreted with the aim of creating harmony in the bodies of humans and various living things. Despite their small amount, these substances have significant effects on living cells. Almost any activity that involves a large number of cells is controlled by hormones. For example, one of the most important glands in the human body, located in the brain, is the hypothalamus, which works to connect the nervous system to the endocrine system through the pituitary gland.
A general classification of the activities of hormones secreted by various glands in the body can be presented in the following five categories:
Regulation of various processes in the body such as behavior, growth, development and reproduction.
Establish coordination between energy production, consumption and storage.
Maintaining a stable body such as keeping water, salt and ions constant.
Preparing the body to react to offensive stimuli such as fighting and running.
General mental states such as feelings of happiness, fear, sadness, romantic relationship and other cases.
In general, it can be said that everything that happens in the human body and living things is controlled by hormones that are secreted by various glands.

This is so good. Especially the categories are so well-explained.😀
