In the fetus, blood formation occurs mainly in the liver and spleen during the early stages of development and later shifts to the bone marrow. In adults, blood formation primarily takes place in the red bone marrow of the axial skeleton (such as the sternum, ribs, vertebrae, and pelvis) and proximal epiphyses of the long bones (such as the femur and humerus). The bone marrow contains stem cells that differentiate into various blood cell types, including red blood cells, white blood cells, and platelets.
the aminotic fluid that the foetus gets before its born and when its a foetus
A teratogen is any substance or factor that can cause birth defects or developmental abnormalities in a growing fetus. These can include drugs, chemicals, infections, and other environmental factors that can negatively impact the development of the embryo or fetus during pregnancy.
The amniotic sac is the membranous fluid filled bubble in which the developing foetus is suspended in utero.
The amniotic fluid of the foetus is tested in amniocentesis to check for abnormalities in the foetus. Unfortunately, it may also lead to female foeticide as the sex of the foetus can also be determined.
An embryo forms first during pregnancy, after fertilization of the egg by sperm. It develops into a fetus around the end of the eighth week of pregnancy.
Up to 8 weeks after fertilization embryo is present which is unborn baby in early stages while foetus is an unborn baby in uterus in later stages of development (after 8 weeks till birth).
An unborn baby that is less than 8 weeks old, is an embryo, after this it is classified as a foetus.
A Foetus is formed by the growth and development of an embryo.
The embryo will develop into a foetus in the womb.
Infant.Zygote, Embryo, Foetus.
Babies don't become embryos, it's the other way around. A fertilised egg becomes a zygote, a zygote becomes an embryo, an embryo becomes a foetus, a foetus becomes a baby.
Well, embryo is the developing stage of a zygote(fertilised egg) when it repeatedly divides itself into a ball of cells to form the different tissues and then the organs of the baby. The stage when the hands, legs , and different body parts of the baby can be identified is termed as the foetus. So, in accordance with your question the stage of the foetus is more developed. However the foetus is not the fully developed stage. The foetus once completely developed , the baby is born.
A baby-to-be is an unborn child, a child which has not yet been born - an embryo or foetus.
A Foetus is formed by the growth and development of an embryo. A Foetus is an unborn baby in the uterus in the later stages of development (after 8 weeks till birth). A Foetus is also multicellular. The body features of developing baby can be identified.
The answer to your question is a zygote. From there, it develops to an embryo and a foetus. Happy science!!!
it has a large food store so the egg can develope into a foetus
