What are the differences between the placenta and the small intestine?
The placenta provides nutrients for the fetus, the small intestine provides nutrients to the mother.
What structure carries blood between the fetus and the placenta?
Umbilical Cord
Could toxins pass through the placenta to the embryo?
Yes, it is possible for this to happen and it can result in fetal death, miscarriage or stillbirth. However, there are several control points in the placenta to help reduce this risk, including the barriers between maternal circulation and fetal circulation.
How nutrients oxygen and waste are exchanged between the fetus and the mother?
how nutrients,oxygen and waste are exchange between the fetus and the mother
How do substances actually get from bloodstream of the mother to the child?
The placenta is responsible for nutrient and gas exchange between the mother and child. This transfer is vital in enabling nutrition be transported from the mother through the placenta to the fetus and expelling waste produced by the fetus back through the placenta and into the maternal blood stream, which is then released by the mother.

When should a parent teach their child about the difference between sexes?
Teaching a child about the differences between the sexes is a personal choice. However, most children learn this information prior to entering pre-school so that they understand the differences between their peers.
What is difference between maternal and paternal?
"Maternal" is of or pertaining to the mother, "paternal" is of or pertaining to the father.
desscribe the structure of the placenta on how it helps it to carry its function?
The placenta is an essential part of pregnancy, serving as a vital connection between mother and baby. It is a complex organ that forms during early pregnancy and is responsible for supplying nutrients and oxygen to the growing fetus, as well as removing waste products from the developing baby's bloodstream. In this blog post, we will discuss the structure of the placenta and how it helps to carry out its crucial functions. The placenta is an organ that develops in the uterus during pregnancy and is attached to the wall of the uterus. The placenta is made up of two parts: the maternal placenta and the fetal placenta. The maternal placenta is composed of the lining of the uterus, while the fetal placenta is made up of the developing baby's tissues. The two parts of the placenta are connected by blood vessels that allow for the exchange of nutrients and waste products between the mother and baby. The structure of the placenta is complex and well-adapted to its function. It has a rich blood supply made up of two sets of blood vessels, the umbilical arteries and veins. The umbilical arteries carry deoxygenated blood from the fetus to the placenta, while the umbilical vein carries oxygenated blood back to the fetus. The placenta also contains a network of small blood vessels called villi. These villi are finger-like projections that extend from the fetal side of the placenta into the maternal blood supply. The villi help to increase the surface area of the placenta, allowing for more efficient exchange of nutrients and waste products. The placenta is also covered in a thin membrane called the chorion. The chorion is the outermost fetal membrane and plays an important role in the development of the placenta. It helps to keep the fetus safe from harmful substances and infections while allowing for the exchange of nutrients and waste products. The placenta is a highly specialized organ that is essential for the healthy development of the fetus. Its unique structure allows for the efficient exchange of nutrients and waste products between mother and baby. The placenta also serves as a protective barrier, keeping harmful substances and infections from reaching the developing fetus. The placenta is a crucial organ that plays an important role during pregnancy. Its complex structure and specialized functions ensure the healthy development of the fetus. Understanding the structure of the placenta can help us appreciate the complexity of human development and the incredible abilities of the human body.
What is the main function of the placenta?
The placenta has several functions in development of the human embryo. # It is an endocrine organ, i.e an organ which secretes hormones from endocrine glands which are ductless. # It is involved in the exchange of substances between the maternal and fetal circulation, e.g. glucose, water, inorganic ions, antibodies, fatty acids, amino acids, etc. # It acts as a barrier bwtween the fetal and maternal circulation for the following reasons - firstly because the mother may have a different blood type to the fetus (i.e. Rhesus Negative when the baby is Rhesus positive) and this stops her from mounting an immune response against the fetus. Secondly because the higher blood pressure of the mother would damage the fetal capillaries, which are very fragile if the placenta wasn't there to act as a barrier. # The blood flow in maternal and fetal capillaries in the placenta is counter-current, in other words they flow in opposite directions, maximising the concentration gradient between them, which is essential for transport of substances by the mechanism of diffusion (e.g. of waste gases like CO2) and facilitated diffusion (e.g of glucose)
How the structure of the placenta is related to its function?
The structure of the placenta is directly related to its function of facilitating nutrient and gas exchange between the mother and fetus. The placenta is composed of villi, which are finger-like projections that increase the surface area for exchange. The villi are surrounded by maternal blood sinuses, allowing for the diffusion of oxygen and nutrients from the mother's blood to the fetal blood, and the removal of waste products from the fetal blood.
