What structure forms between a mother and her unborn baby and does the work of several organs?
The placenta is crucial to keeping your baby alive and well during pregnancy. It is an organ attached to the lining of the womb that delivers oxygen and nutrients to the growing baby. Show
About the placentaThe placenta is a large organ that develops during pregnancy. It is attached to the wall of the uterus, usually at the top or side. The umbilical cord connects the placenta to your baby. Blood from the mother passes through the placenta, filtering oxygen, glucose and other nutrients to your baby via the umbilical cord. The placenta also filters out substances that could be harmful to your baby and removes carbon dioxide and waste products from your baby’s blood. The placenta produces a number of hormones that are needed during pregnancy, such as lactogen, oestrogen and progesterone. It keeps the mother’s blood separate from the baby’s blood to protect the baby against infections. Towards the end of the pregnancy, the placenta passes on antibodies to protect the baby after birth. Alcohol, nicotine and other drugs and medicines can cross the placenta and damage your baby. What happens to the placenta during pregnancy?The placenta often develops low in the womb but moves to the side or up as the womb stretches. The position of the placenta will be checked at your 18-week ultrasound. The placenta is expelled from your body after the birth, usually about 5 to 30 minutes after your baby is born. This is called the third stage of labour. After the baby is born you will continue to have mild contractions. You will have to give one more push to deliver the placenta. Sometimes your abdomen will be massaged or you will be given an injection of oxytocin and the umbilical cord will be gently pulled to help deliver the placenta. If you have a caesarean section, the doctor will remove the placenta at the same time. It is important that the whole placenta comes out after pregnancy. If any fragments of the placenta stay inside, they will have to be surgically removed to prevent bleeding and infection. How to keep your placenta healthyIt is important to visit your healthcare provider regularly during pregnancy to check for any problems with your placenta. Tell your doctor if you have had problems with the placenta in a previous pregnancy, or if you have had any surgery to your womb. Don’t smoke, drink alcohol or take illegal drugs during pregnancy because this increases the likelihood you will have problems with the placenta. Always consult your doctor before you take any medicines, including over-the-counter medicines, natural therapies and supplements, while you are pregnant. Speak with your doctor or midwife if you have any concerns, or if you experience:
Placenta complicationsProblems with the placenta can potentially be dangerous for both mother and baby:
Options for the placenta after the birthIn some cultures, families bury the placenta in a special place. There is also a rare practice, known as placentophagy, in which women cook and eat the placenta. Some commercial service providers will offer to turn your placenta into capsules for you to swallow. However, these practices should be treated with caution since there is no regulation in Australia either of these products or the providers of placenta pills. Recent research shows there are no known health benefits from eating the placenta, but there may be a risk of infection from poor production standards. What is the bundle of three blood vessels that connects an unborn baby with the placenta?The unborn baby is connected to the placenta by the umbilical cord. All the necessary nutrition, oxygen, and life support from the mother's blood goes through the placenta and to the baby through blood vessels in the umbilical cord.
Which organ is bypassed by the special circulation pathways of a fetus?Most of the blood that leaves the right ventricle in the fetus bypasses the lungs through the second of the two extra fetal connections known as the ductus arteriosus. The ductus arteriosus sends the oxygen poor blood to the organs in the lower half of the fetal body.
