Chemical Coordination and Integration - Hormones
Hormones are chemical messengers that are released directly into the bloodstream, where they are carried to organs and tissues throughout the body to perform their tasks. Hormones are released by the body's endocrine glands.
Functions of Hormones
Following are some important functions of hormones:
- Food metabolism.
- Growth and development.
- Controlling thirst and hunger.
- Maintaining body temperature.
- Regulating mood and cognitive functions.
- Initiating and maintaining sexual development and reproduction.
Types of Hormones
To regulate various functions, different types of hormones are produced in the body. They are classified as follows:
- Peptide Hormones: Peptide hormones are composed of amino acids and are soluble in water.
- Steroid Hormones: Unlike peptide hormones, steroid hormones are fat-soluble and are able to pass through a cell membrane.
