brings the embryo and mother's blood close together but prevents them from mixing driectly; permits food and oxygen to reach the organism and waste products to be carrier away
how the placenta is connected to the developmenting organism; contains one large vein that delivers blood loaded with nutrients and two arteries that remove waste products
the period that lasts from implantation through the 8th week of pregnancy; during these 6 weeks the groundwork is laid for all body structures and organs
the period from the 9th week to the end of pregnancy; the longest prenatal period. during this "growth and finishing" phase the organism increases rapidly in size

Fetal Alcohol Spectrum Disorder (FASD)
a term encompassing a range of physical, mental, and behavioral outcomes
Fetal Alcohol Syndrome (FAS)
distinguished by slow physical growth, facial abnormalities (short eyelid openings, a thin upper lip, and a smooth or flattened philtrum, or an indentation running from the bottom of the nose to the center of the upper lip), and brain injury evident in a small head and impairment in at least three areas of functioning (such as memory, lamguage and communication, attention span and activity level-overactivity, planning and reasoning, motor coordination, or social skills)
Partial Fetal Alcohol Syndrom (p-FAS)
characterized by 2 of 3 facial abnormalities and brain injury as found in FAS; mothers of these children usually generally drank smaller quantities, and the children's defects vary with the timing and length of alcohol exposure
Alcohol-Related Neurodevelopment Disorder (ARND)
at least 3 levels of mental functioning are impaired, despite typical physical growth and absence of facial abnormalities; alcohol exposure is less pervasive than in FAS
Rh Factor Incompatability
when the mother is Rh-negative (lacks the Rh blood protein) and the father is Rh-positive (has the protein), the baby may inherit the father's Rh-positive blood type. if the fetus's Rh-positive blood crosses into the mother's blood stream she begins to form antibodies that will destroy RBCs and reduce the oxygen supply to organs and tissues if they enter the fetus's system
assesses the newborn's physical condition quickly; two rating are given because some babies have trouble adjusting at first but do quite well after a few minutes

Rapid-eye-movement (REM) sleep
during this, brain-wave activity is remarkably similar to that of the waking state. the eyes dart beneath the lids; heart rate, blood pressure, and breathing are uneven; and slight body movements occur
Non-rapid-eye-movement (NREM) sleep
the body is almost motionless, and heart rate, breathing, and brain-wave activity are slow and even
Sudden Infant Death Syndrom (SIDS)
the unexpected death, usually during the night, of an infant under 1 year of age that remains unexplained after thorough investigation
