Nutrients and Waste
Nutrients, oxygen, and waste are exchanged between the fetus and the mother through the placenta, a temporary organ that develops during pregnancy. The mother's blood containing nutrients and oxygen passes through the placenta, where it comes into close contact with the fetal blood vessels. Through diffusion and active transport processes, nutrients and oxygen are transferred from the mother's blood to the fetal blood, while waste products such as carbon dioxide are transferred from the fetal blood to the mother's blood for elimination.
Oxygen, nutrients (such as glucose and amino acids), antibodies, hormones, and waste products (such as carbon dioxide and urea) can be exchanged between the mother and fetus through the placenta. These substances allow for the fetus to receive essential supplies for growth and development while also enabling waste removal.
placenta
Materials pass back and forth between the fetus and the mother through the placenta. The placenta is a temporary organ that provides oxygen and nutrients to the fetus while removing waste products. It allows for the exchange of gases, nutrients, and waste between the maternal and fetal bloodstreams without the two blood supplies mixing.
Small microbes like illnesses can get through it and smoking, drugs and alcohol can get through as well.
Volcanic activity.
Materials are exchanged between cells and the blood mainly at the capillaries. Capillaries are tiny blood vessels with thin walls that allow for the exchange of gases, nutrients, and waste products between the blood and surrounding tissues. This exchange process occurs through the process of diffusion.
Through the umbilical cord and the placenta.
Nutrients and other needed materials diffuse from the mother's blood through the placenta which connects the fetus the the uterus lining.
The embryo gets nutrients from the mother during pregnancy through the placenta. The placenta is a temporary organ that develops in the uterus and allows for the exchange of nutrients, oxygen, and waste products between the mother and the fetus.
