What are four environmental hazards that can affect a fetus?
These chemicals include commonly known hazards such as lead, mercury, and environmental tobacco smoke, as well as some pesticides, solvents, products containing chlorine, and other chemicals referred to as “persistent organic pollutants.” The fetus is particularly vulnerable to environmental chemicals that can disrupt …
How can the environment affect a fetus?
Environmental concerns when pregnant. Exposure to certain substances in the environment when you are pregnant may affect your pregnancy or the health of your baby. Toxic substances increase the risk for birth defects, low birth weight, prematurity and miscarriage.
What are 3 environmental factors that affect prenatal development?
Other teratogens that affect prenatal development include radiation, pollution, and infectious disease. Radiation increases the risk of childhood cancer, as well as emotional and behavioral disorders; because of this, it is recommended that pregnant women avoid x-rays unless absolutely necessary.
How can environmental hazards affect prenatal development?
While environmental exposure is how many diseases and conditions are acquired, developing fetuses are particularly vulnerable to these. The effects of environmental hazards on pregnancy can be severe and include disruptions in fetal growth, congenital anomalies, stillbirth, and pregnancy loss.
What factors can affect fetal development?
Genetic, nutritional, environmental, uteroplacental, and fetal factors have been suggested to influence fetal growth. Uteroplacental and umbilical blood flow and transplacental glucose and fetal insulin are major determinants of fetal growth.
What can affect fetal development?
Factors affecting fetal growth can be maternal, placental, or fetal. Maternal factors include maternal size, weight, weight for height, nutritional state, anemia, high environmental noise exposure, cigarette smoking, substance abuse, or uterine blood flow.
What environmental factors may cause malformations in the developing embryo?
An environmental cause can include drugs, alcohol, or a disease the mother has that can increase the chance for the baby to be born with a birth defect. An agent that can cause a birth defect is known as a teratogen. Multifactorial birth defects are caused by a combination of genes and environmental exposures.
What is an example of an environmental influence during the prenatal stage?
The prenatal environment:
The chemical balance of the mother’s body and the presence of conditions or potentially toxic substances that can alter development processes. Examples are the mother’s use of drugs or alcohol, viral or bacterial diseases, and direct traumatic injury to the fetus.
What are environmental factors?
Environmental factors include temperature, food, pollutants, population density, sound, light, and parasites. The diversity of environmental stresses that have been shown to cause an increase in asymmetry is probably not exclusive; many other kinds of stress might provide similar effects.
What are some environmental factors that influence development?
Over the past 100 years, the study of environmental influences on human physical growth and development has focused on the influences of social and economic factors; family and household characteristics; urbanization/modernization; nutrition; and features of the physical environment such as altitude, temperature and …
What environmental influences can affect prenatal development quizlet?
-Important environmental influences involving the mother include nutrition, physical activity, smoking, intake of alcohol or other drugs, maternal illness, maternal stress, maternal age, and external environmental hazards, such as chemicals and radiation.
