Which gland secretes odorous secretion in mammals:
- Bartholins
- Prostate
- Anal gland
- Liver-bile
The Correct Option is C
Solution and Explanation
The gland that secretes odorous secretion in mammals is the Anal gland. Anal glands, also known as anal sacs, are found near the anus and contain a foul-smelling secretion that can be used for scent marking, communication, and defense in some mammals.
So, the correct option is (C): Anal gland

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.

- Cortisol
- Estrogen
- Melatonin
- Progesterone
- Testosterone
