FAQs on Parturition & Lactation Video Lecture - NEET
| 1. What is parturition and lactation? |  |
Ans. Parturition refers to the process of giving birth to offspring, while lactation is the production and secretion of milk from the mammary glands after childbirth.
| 2. How does parturition occur in humans? | |
Ans. In humans, parturition is typically triggered by a complex hormonal interplay. The rise in estrogen levels stimulates the production of oxytocin, which leads to uterine contractions. These contractions gradually increase in intensity and frequency, eventually leading to the expulsion of the fetus through the birth canal.
| 3. What are the hormones involved in lactation? | |
Ans. Lactation is primarily regulated by two hormones: prolactin and oxytocin. Prolactin is responsible for the production of milk in the mammary glands, while oxytocin stimulates the let-down reflex, causing the milk to be released and flow through the milk ducts.
| 4. How long does lactation typically last? | |
Ans. The duration of lactation varies among individuals, but it generally lasts for as long as the infant continues to breastfeed. Exclusive breastfeeding is recommended for the first six months of a baby's life, and then it can be continued alongside solid foods until the age of one or beyond.
| 5. What are the benefits of breastfeeding for both the mother and the baby? | |
Ans. Breastfeeding provides numerous benefits for both the mother and the baby. For the baby, it offers optimal nutrition, protection against infections and diseases, and promotes bonding with the mother. It also reduces the risk of obesity and certain chronic conditions later in life. For the mother, breastfeeding helps in postpartum recovery, promotes bonding with the baby, and reduces the risk of breast and ovarian cancers.
