Lactation in Human

The term lactation refers to the secretion and ejection of milk by the mammary glands.

• Lactation is the process by which mammary glands produce milk at the end of pregnancy, under the influence of the hormone Prolactin.
• The first milk secreted soon after childbirth is called Colostrum — it is sticky, yellowish and rich in proteins, lactose and antibodies (IgA); fat content is low.
• Antibodies (especially IgA) in colostrum provide passive immunity to the newborn when its own immune system is not yet fully developed.
• Lactation helps the mother in feeding and nourishing the newborn baby, providing all essential nutrients required in early life.
