Hormones

Prepared by: Zhubanova Gaziza

What are Hormones?

Hormones are 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. Some of these include:

• Development and growth
• Metabolism of food items
• Sexual function and reproductive growth and health
• Cognitive function and mood
• Maintenance of body temperature and thirst

Where are they secreted from?

Hormones are secreted from the endocrine glands in the body. The glands are ductless, so hormones are secreted directly into the blood stream rather than by way of ducts. Some of the major endocrine glands in the body include:

• Pituitary gland
• Pineal gland
• Thymus
• Thyroid
• Adrenal glands
• Pancreas
• Testes
• Ovaries

These organs secrete hormone in microscopic amounts and it takes only very small amounts to bring about major changes in the body. Even a very slight excess of hormone secretion can lead to disease states, as can the slightest deficiency in a hormone.
