A teat is a small, protruding structure found on the bodies of mammals, primarily used for nursing. It is where milk is delivered from the mammary glands to the young during feeding. Teats can vary in size and shape depending on the species, and they are typically located on the underside of the body. In addition to mammals, the term "teat" can also refer to similar structures in other animals, such as goats and cows, which are commonly farmed for their milk. Teats play a crucial role in the survival and growth of young mammals, providing essential nutrients and hydration.
