Physiology of Lactation

Lactation is a natural process through which mammals produce and secrete milk to nourish their offspring, ensuring their growth and development. This process is most prominent in female mammals after giving birth, but in some cases, it can occur without pregnancy as well. The physiology of lactation involves complex interactions between hormones, glands, and the nervous system, all working together to produce, regulate, and release milk. This article aims to describe the physiology of lactation, focusing on the key processes that enable the production and secretion of milk in mammals.

Hormonal Control of Lactation:

Lactation is primarily governed by hormones, with prolactin and oxytocin being the key players in regulating the process. Prolactin is a hormone secreted by the pituitary gland in response to the hypothalamus detecting low levels of prolactin-inhibiting factor (PIF).

After delivery, the placenta is expelled, and estrogen __ ___ ____________ _________ _______ ______ __________ _____ ________ _________ _________ _________ ____.
