What is the process of Milk secretion called?

The process of milk secretion is referred to as lactation. This biological process occurs in mammals, where specialized glands, known as mammary glands, produce milk to feed their young. Lactation is triggered by hormonal changes that occur during pregnancy and after childbirth. The primary hormone involved in lactation is prolactin, which stimulates the production of milk, while oxytocin helps with the ejection of milk during breastfeeding.

In contrast, ingestion refers to the act of consuming food or drink, while digestion involves breaking down food in the stomach and intestines into smaller components the body can absorb. Absorption is the process by which the nutrients from digested food are taken into the bloodstream from the intestines. Each of these processes is essential for nutrition and health, but they do not pertain directly to the secretion of milk, which is specifically what lactation describes.
