Final answer:
The milk-like substance secreted right after delivery is called colostrum. Colostrum is a thick, yellowish substance that is high in protein but contains less fat and glucose than mature breast milk.
Step-by-step explanation:
Lactation is the process by which milk is synthesized and secreted from the mammary glands of the postpartum female breast in response to an infant sucking at the nipple. Breast milk provides ideal nutrition and passive immunity for the infant, encourages mild uterine contractions to return the uterus to its pre-pregnancy size (i.e., involution), and induces a substantial metabolic increase in the mother, consuming the fat reserves stored during pregnancy.
The milk-like substance secreted right after delivery is called colostrum. Colostrum is a thick, yellowish substance that is high in protein but contains less fat and glucose than mature breast milk. It provides immunoglobulins that increase the newborn's immune defenses.
