- The placenta (also known as afterbirth) is an organ that connects the developing fetus to the uterine wall to allow nutrient uptake, thermo-regulation, waste elimination, and gas exchange via the mother's blood supply; fight against internal infection; and produce hormones to support pregnancy.

Prenatal Development: How Your Baby Grows During Pregnancy The placenta is formed from some of these rapidly dividing cells. The placenta functions as a life-support system during. pregnancy. Oxygen, nutrients, and hormones from the mother are transferred across the placenta to reach the baby, and. waste products from the baby are transferred to the mother for removal.

Endocrine-related Organs Although these organs are not glands themselves, they do produce, store, and send out hormones that help the body to function properly and maintain a healthy balance. Placenta. Besides providing a connection between mother and fetus, the placenta is a special endocrine organ.

- The placenta is a temporary endocrine organ formed during pregnancy, which produces hormones important in the maintenance of a healthy pregnancy and in preparation for labour and breastfeeding. Blood vessels in the placenta bring oxygen and nutrients to the foetus and remove waste products.

8 Nutrients Most Essential for Fetal Development Pregnant women can’t simply eat whatever they want, as a balanced diet is crucial for healthy fetal development. If you fail to get certain nutrients while your baby is forming, you risk subjecting the fetus to birth defects and learning disabilities.

- 1 Oxygen is transported across the placenta combined with Haemoglobin in the mother's blood. The mother and fetus have different types of haemoglobin - fetal haemoglobin has a higher affinity for oxygen than maternal haemoglobin. 2  Waste gases such as carbon dioxide diffuse down a concentration gradient, passively out into the mother's blood.

The Life Cycle of the Placenta “The placenta is an organ which provides the fetus with oxygen, water, and essential nutrients as well as providing a route for clearance of fetal waste products like carbon dioxide,” says Dr. Natour.

Blood Circulation in the Fetus and Newborn The fetus is connected by the umbilical cord to the placenta, the organ that develops and implants in the mother's uterus during pregnancy. Through the blood vessels in the umbilical cord, the fetus receives all the necessary nutrition, oxygen, and life support from the mother through the placenta. Waste products and carbon dioxide from the fetus are sent back through the umbilical cord and placenta to the mother's circulation to be eliminated.

- The spleen is the organ that is responsible for both the storage and purification of red blood cells. It is positioned in the left upper abdomen, and is the largest organ of the lymphatic system. The spleen serves a critical role in immune function because it purifies the blood and helps the immune system to recognize and attack foreign pathogens and allergens. The spleen is composed of the red pulp and white pulp. The white pulp produces and grows immune cells as well as blood cells. On the other hand, the red pulp is responsible for purifying the blood and removing dead or old blood cells.

What is the function of the appendix? For years, the appendix was credited with very little physiological function. We now know, however, that the appendix serves an important role in the fetus and in young adults. Endocrine cells appear in the appendix of the human fetus at around the 11th week of development.

How Does Nutrition Get From the Placenta to the Fetus? As cells divide and differentiate, the developing baby begins as a zygote, forms into a blastocyst, becomes an embryo and then transforms into a fetus, all in the first trimester of pregnancy. From the very beginning, the developing cells need oxygen and nutrients. The fetus receives its nutrition from the mother through the placenta and the umbilical cord. The placenta--defined as a temporary organ consisting of blood vessels and membranes that unite mother and fetus--begins to develop as the blastocyst, a hollow ball of cells, implants in the uterus.

- The placenta functions as a fetomaternal organ with two components: the fetal placenta and the maternal placenta. The placenta connects to the fetus by an umbilical cord, which contains two arteries and one vein.

Umbilical Cord Blood Gases and Hypoxic Ischemic Encephalopathy | Birth Injury Diagnosis Rather, “breathing” (gas exchange) occurs in the intervillous space in the placenta. The placenta is an organ that connects the developing fetus to the uterine wall to allow for nutrient uptake, waste elimination and gas exchange via the mother’s blood supply.

- Some metabolic waste is passed from the fetus back to the mother via the umbilical cord. Other metabolic waste is simply excreted directly into the amniotic fluid. This wast … e can frequently be seen in the amniotic fluid when the baby is born. Karin L.

Exchange of gases nutrients and wastes between the fetal and maternal sides of the placenta occurs by? 1 Oxygen is transported across the placenta combined with Haemoglobin in the mother's blood. 2  Waste gases such as carbon dioxide diffuse down a concentration gradient, passively out into the mother's blood. Water crosses the placenta by osmosis, due partly to differences in blood pressure of the mother and fetus, and hence down a water potential gradient. Again, this is a passive process.

chorionic villi Oxygen and nutrients in the maternal blood diffuse through the walls of the villi and enter the blood of the embryo or fetus. Carbon dioxide and waste products diffuse from blood in the fetal capillaries through the walls of the villi into the maternal blood. See also chorionic villus sampling. [vil´us] (L.)

- The lungs are a pair of organs in the chest that are primarily responsible for the exchange of oxygen and carbon dioxide between the air we breathe and the blood.

Fetal Development During prenatal development, the fetal circulatory system is integrated with the placenta via the umbilical cord so that the fetus receives both oxygen and nutrients from the placenta. However, after childbirth, the umbilical cord is severed, and the newborn’s circulatory system must be reconfigured.

The Structure and Function of the Digestive System Peristalsis also is at work in this organ, moving food through and mixing it with digestive secretions from the pancreas and liver. The duodenum is largely responsible for the continuous breaking-down process, with the jejunum and ileum mainly responsible for absorption of nutrients into the bloodstream.

- The essential function of the chorion is to develop the villi and the placenta that will provide a pathway for exchange from the mother to the fetus, making it a pivotal part of the pregnancy.unction of the Chorion. While a fetus is developing inside the mother, it is totally dependent on her for nutrition and removal of wastes. As the chorion develops, the side that is facing the fetus becomes the placenta.

Placenta: How it works, what's normal The placenta is an organ that develops in your uterus during pregnancy. This structure provides oxygen and nutrients to your growing baby and removes waste products from your baby's blood. The placenta attaches to the wall of your uterus, and your baby's umbilical cord arises from it. In most pregnancies, the placenta attaches at the top or side of the uterus.

- of the body of the fetus. Functions associated with respiratory processes begin, although the lungs of the fetus are not yet fully developed. The exchange of oxygen and carbon dioxide is still done in the placenta at this point. At 20 weeks, the fetus cannot survive outside of the uterus.
