Episode Details

First aired: June 18, 2013.

This lesson focuses on the physical changes of early adulthood—the period between ages 18 and 35. Young adults are at their physical peak. Now on their own, these young adults are responsible for making decisions that affect their physiological development: what foods they eat and whether to drink alcohol, smoke cigarettes, or use other drugs. Biological topics explored in this lesson include organ reserve, homeostasis, pregnancy, and early signs of physiological decline. The video lesson also considers the health risks posed by eating disorders, such as anorexia and bulimia, and by violence and risk-taking behaviors.
