TED-Ed: The surprising effects of pregnancy | TED-Ed

Pregnancy triggers significant changes in a woman's body, affecting every organ system. Hormones initiate these changes, which include adaptations in the immune system to protect the fetus, digestive and respiratory adjustments, and increased blood volume. The heart works harder to circulate blood, and the uterus expands, impacting other organs. Before birth, some changes begin to reverse. Pregnancy also affects the brain, potentially enhancing parenting skills. Historically, research has focused more on the fetus than the mother, but new studies aim to understand these changes better.
