How does a woman's body produce milk?

Dandelion medical animation All rights reserved. When a woman becomes pregnant, her body undergoes hormonal changes, primarily influenced by two hormones: estrogen and progesterone. These hormonal shifts prepare the breasts for milk production. Shortly before childbirth, another hormone called prolactin, which is responsible for milk production, increases in the woman's body. After delivery, when the baby begins to suckle at the breast, it stimulates the nerves in the nipple and areola, sending signals to the brain. Within the breasts, there are small clusters of glandular tissues called alveoli. These alveoli are responsible for producing milk. During pregnancy, under the influence of hormonal changes, these alveoli begin to multiply and enlarge. The mother's breasts got around 150,000 alveoli in each breast. This is many times more than the number of alveoli that a non-pregnant woman has. The extra alveoli help ensure the mother can produce enough milk to feed her baby. Inside each alveolus, there are specialized cells called secretory cells or alveolar cells. These cells are the key players in milk production. They produce and secrete milk components such as proteins, fats, lactose, and immune factors. In response to the baby's sucking and nipple stimulation, the hormone oxytocin is released from the pituitary gland in the brain. Oxytocin triggers the let-down reflex, also known as the milk ejection reflex. This reflex causes the muscles around the alveoli to contract, pushing the milk into the milk ducts and out through the nipple. Breast milk production operates on a supply-and-demand basis. The more frequently and effectively the baby nurses, the more milk is produced. When the baby empties the breasts during feeding, it signals to the body to produce more milk to meet the baby's needs. 3dmedicalanimation copyrighted_by_Dandelion _Team vaginal birth-natural childbirth    • Vaginal-Birth, Natural -Childbirth   Sexual desire, also known as libido, can vary significantly among individuals    • Sexual desire, also known as libido, can v...   the female body and Biology | Biology of Female    • female orgasm | Female anatomy and biology   Hemorrhoids|different types of hemorrhoids    • Hemorrhoids|different types of hemorrhoids...   Virginity and hymen    • Virginity and hymen!can you Confirm a pers...   Fertilization medical animation    • Fertilization|medical animation #sperm   we all won this race!    • Fertilization | 3d medical animation #sper...   What role does sperm structure play in fertilization?    • What Is Sperm?What is sperm made of? medic...   ovulation and menstrual cycle often called period    • ovulation and menstrual cycle often called...   The effect of Tied umbilical cord in twins    • The effect of Tied umbilical cord in twins...   High Blood Pressure Hypertension    • High Blood Pressure|Hypertension|Medical A...   How your body turns food into the poo Human digestion system in human beings    • How does your body turn food into the poop...   food digestion is the story of how your food ends up as a poo 3d medical animation dandelion team    • food digestion the story of how your food ...   coronary angiogram Micro Needle|3d medical animation|sample use only    • coronary angiogram Micro Needle|3d medical...   heart valve replacement 3d medical animation|sample use only|dandelion team    • Heart Valve Replacement| to replacing hear...   short videos how long does it take for the body to digest food?    • how long does it take for the body to dige...   The world of inside a bone    • inside a bone #bone #bones   What Part of the Brain Controls Emotions?    • What Part of the Brain Controls Emotions? ...   small intestine    • small intestine #digestivesystem #alcohol   #breastfeeding copyright by Dandelion Team
