Animal secretions are substances produced by animals that serve various functions in their bodies. These secretions can include saliva, sweat, urine, and mucus, each playing a role in processes like digestion, temperature regulation, and waste elimination. For example, saliva helps break down food, while sweat cools the body. In addition to these common secretions, some animals produce specialized substances. Bees secrete wax to build their hives, while spiders produce silk for webs. These secretions are essential for survival, aiding in communication, protection, and reproduction within different species.
