Question

What are animal hormones?

Answer 1

Animal hormones:- Animal hormones are chemicals that are secreted by the endocrine glands. Hormones are made by all organ systems and tissues in the body.

• Animal hormones are carried by the blood to the respective organs to regulate their physiological processes.
• The organs on which the hormones act are known as the target organs. The target cells on the organs have receptors that recognize the respective hormones on their surface.
• Hormones in animals conduct a wide variety of functions from growth, sexual development, vegetative development, cellular respiration, metabolism, thermal production, and so on.
• The nervous system coordinates rapid activities of animals like movement, while hormones integrate the coordination.
• Larger complex animals like vertebrates have endocrine glands to produce hormones.

Characteristics of animal hormones include:

1. Hormones are secreted by the endocrine glands in small amounts.
2. The hormones are secreted directly into the blood and it is transported throughout the body.
3. They are chemical messengers that regulate the behavior of the target cells.
4. The specific hormones act only on the target organs.
