The circulatory system moves oxygenated blood to all parts of the body. Without oxygen being carried to cells they would die thus causing the animal to die.
Frontal, parietal, temporal, and occipital lobes make up the cerebral cortex.
The fetus can be screened for abnormalities using karyotyping and biochemical analysis using amniocentesis and chorionic villus sample.
<h3>What data can we glean from CVS and amniocentesis?</h3>
In at-risk fetuses, these tests can detect genetic illnesses such cystic fibrosis, Tay-Sachs disease, and sickle cell disease. The main benefit of CVS over amniocentesis is that it is done considerably earlier in pregnancy—at 10 to 13 weeks as opposed to 15 to 20 weeks—thus saving more time for the mother.
<h3>What can a couple learn about their growing fetus from amniocentesis and chorionic villus sampling?</h3>
Amniocentesis and chorionic villus sampling (CVS) are prenatal diagnostic techniques used to identify certain fetal genetic disorders. The likelihood of miscarriage rises with both procedures.
