Final answer:
Pregnant teens face medical risks including exposure to teratogens, infections, and substance abuse.
Step-by-step explanation:
The medical risks for pregnant teens include exposure to teratogens, infections, and substance abuse.
Teratogens are substances or factors that can cause birth defects or developmental abnormalities in the embryo or fetus. Examples of teratogens include drugs like heroin, cocaine, and methamphetamine, as well as certain medications and viruses like HIV and rubella.
Infections during pregnancy can lead to serious illness or death in newborns. Pregnant teens are at risk of developing infections that can harm both themselves and their babies. Finally, substance abuse, such as alcohol consumption and smoking, can have detrimental effects on the health of both pregnant teens and their babies.
