NEET BIOLOGY

Detailed explanation-1: -The placenta plays a key role in the nutrition of the fetus. It mediates the active transport of nutrients and metabolic wastes across the barrier separating maternal and fetal compartments, as well as modifying the composition of some nutrients through its own metabolic activity.

Detailed explanation-2: -Placental transport provides a means of supplying nutrients to and removing metabolites from the fetus. Transport is based on substrate exchange and net flux from mother to fetus or vice versa and can be a result of a concentration difference or of unidirectional carrier-mediated transport.

Detailed explanation-3: -The placenta is an organ that develops in the uterus during pregnancy. This structure provides oxygen and nutrients to a growing baby. It also removes waste products from the baby’s blood. The placenta attaches to the wall of the uterus, and the baby’s umbilical cord arises from it.

Detailed explanation-4: -Your blood passes through the placenta and provides oxygen, glucose and nutrients to your baby through the umbilical cord. The placenta can also filter out harmful waste and carbon dioxide from your baby’s blood.

Detailed explanation-5: -Protein is transported to the fetus as amino acids by specific amino acid transporter proteins. Placental lipid transport to the fetus involves direct transporter mediated transfer of certain fatty acids as well as lipid uptake from lipoproteins, metabolic alteration in the placenta, and release into the fetal plasma.
