abnormal genes or inheritance of an abnormal number of chromosomes. Birth defects also may be caused by exposure to environmental factors called teratogens (TAYR-ahtoh-jenz). Teratogens include radiation (for example‚ x-rays)‚ chemicals (for example‚ drugs‚ cigarettes‚ or alcohol)‚ and infections in the mother (for example‚ herpes or rubella).

How satisfied with life one may be at late adulthood is usually determined by experiences. Satisfaction with life is subjective because of the variations is experiences from one person to another.

hormones pass through the placental barrier from the mother and into the fetus’ bloodstream. Additionally‚ umbilical cord transports materials such as nutrients to the fetus. Due to the direct connection‚ mothers are strongly advised not to consume teratogens such as alcohol‚ drugs‚ or other substance that may be detrimental to a fetus during pregnancy. Intangible factors such as stress on the mother‚ however‚ is often ignored. Yet‚ stress during pregnancy also negatively effects the fetus due to effects
