What Passes Through Placental Barriers? Maternal-to-fetal transfer occurs across the placental barrier, made up of both the syncytiotrophoblast on the maternal side and the endothelial cell layer on the fetal side. Which of the following agents would most readily cross the placenta? Induction agents Thiopental is the most commonly used induction agent in parturients. It
Which Condition Is Necessary For Enzymes And Hormones To Function Properly In The Human Body? Most enzymes in the human body work best at around 37°C – body temperature. At lower temperatures, they will still work but much more slowly. Similarly, enzymes can only function in a certain pH range (acidic/alkaline). Their preference depends on
What Crosses Placental Barrier? Drugs that have low molecular weight, lipid (fat) solubility, nonpolarity, and no protein binding properties will quickly and easily cross the placenta. Alcohol, for example, readily reaches the embryo in fairly high concentrations. What drugs cross the placental barrier? Most drugs with MW < 500 Da cross the placenta, and most
