Hormones

Hormones are chemical messengers produced by the endocrine glands in the body. They are essential for regulating various bodily functions, including growth, metabolism, and reproduction.

Types of Hormones

There are several types of hormones, including:

• Steroid Hormones: These are derived from cholesterol and include hormones such as estrogen, progesterone, and testosterone.
• Peptide Hormones: These are made up of amino acids and include hormones such as insulin and growth hormone.
• Amino Acid-Derived Hormones: These are derived from amino acids and include hormones such as epinephrine and thyroid hormones.

Functions of Hormones

Hormones play a crucial role in the body, including:

• Regulating metabolism
• Controlling growth and development
• Regulating reproductive processes
• Managing stress responses
• Controlling fluid and electrolyte balance

Regulation of Hormones

Hormone levels in the body are tightly regulated through a feedback system involving the endocrine glands and target organs. This ensures that the body maintains a state of balance known as homeostasis.
