Hormones as Chemical Messengers

Hormones are produced by glands in the endocrine system and play a critical role in various functions of the body.
These substances are responsible for transmitting information and coordinating activities throughout the body.
Hormones function as chemical messengers, communicating between cells in various parts of the body.
Each hormone has a specific function and regulates specific cells or organs.
Hormones are released directly into the bloodstream and are transported to target cells or organs.
Hormone levels in the body are typically regulated by a system of feedback mechanisms, ensuring the body’s internal processes remain balanced.
Examples of hormones include insulin released by the pancreas to regulate blood glucose levels, and adrenaline released by the adrenal glands to prepare the body for a ‘fight or flight’ response.
Hormones also play a large role in the human reproductive system, such as oestrogen and progesterone in females and testosterone in males.
Disorders in hormonal balance or production can lead to various health issues, such as diabetes, hyperthyroidism, or hypothyroidism.
Most hormonal changes are normal, such as those occurring throughout puberty or menstrual cycles; however, they can also be induced by stress, illness, or medications.
Hormone release and regulation is a key aspect of homeostasis, maintaining the stability and proper functioning of the body’s internal environment.
