From the preceding account of the circulation of the blood in the fetus the following facts will be evident: (1) The placenta serves the purposes of nutrition and excretion, receiving the impure blood from the fetus, ...

fetus
[L. pregnant]
An unborn or unhatched vertebrate that has passed through the earliest developmental stages; a developing human from about the second month of gestation until birth.

Fetus: Final development stage before birth (following embryo).
Fingerprinting: The use of RFLPs or repeat sequence DNA to establish a unique individual-specific pattern of DNA fragments.

Amniocentesis
During its development, the fetus sheds cells into the amniotic fluid.

The fetus is surrounded by a layer of liquid called amniotic fluid. Amniocentesis is a technique in which a sample of amniotic fluid is removed and cells that it contains are grown on a culture dish.

The fetus increases in size during this trimester, and bony parts of the skeleton begin to form. Fetal movements can be felt by the mother.
The Last Trimester ...

In the fetus, at an early period, the greater part of the skeleton is cartilaginous; as this cartilage is afterward replaced by bone, it is called temporary, in contradistinction to that which remains unossified during the whole of life, ...

In the fetus, the blood comes from the umbilical vein (oxygenated blood from the placenta) to the right atrium. Since the lungs are not functioning yet, they are collapsed and only a small portion of the blood goes to nourish them.

If you have a fetus that's developing in uniformly high concentrations of retinoic acid you'd have then high concentrations not only back here where they belong, but also up here.

Advanced maternal age -- women over age 34 (age 35 at delivery) at increased risk for nondisjunction trisomy in fetus. Alcoholism -- a chronic and progressive condition characterized by the inability to control the consumption of alcohol.

Hemophiliacs suffer from defective Factor VIII, which can be detected in fetuses 20 weeks old.

Patient A Patient A is the nearly-full-term fetus of a forty year old female. Chromosomes were obtained from fetal epithelial cells acquired through amniocentesis. Complete Patient A's Karyotype.

A substance produced by the fetus that is found in fetal serum, amniotic fluid, and the mother's bloodstream.

In mammals, a tissue formed within the uterus through which nutrients are passed from the mother to the embryo (and later the fetus) and its wastes are removed. It is analogous to the protective membranes in the egg of other amniotes.

So when you were a fetus (in the womb before you were born) you had something called a notochord. That's a rod made out of cartilage. As you developed, that cartilage turned into a spinal cord made out of bones.

placenta - embryonic/maternal organ that serves nutritional and respiratory functions of the mammalian fetus.

[Gr. amnion - the membrane around the fetus]. An extraembryonic membrane surrounding the embryo and containing the amniotic fluid which protects the embryo from shock and desiccation. It consists of ectoderm and somatic mesoderm.

Origin: L. Femininus, fr. Femina woman; prob. Akin to L. Fetus, or to gr. To suck, to suckle, Skr. Dha to suck; cf. As. Famme woman, maid: cf. F. Feminin. See foetus.
1. A woman. They guide the feminines toward the palace. (Hakluyt) ...

amniotic fluid
Watery-fluid that bathes the fetus keeping it suspended to act as a protective cushion.

We also get karyotypes when pregnant women choose to have testing on their unborn fetus, and the karyotype allows the providers to look at and count the chromosomes to determine whether or not the child is affected by having an extra chromosome.
