Pregnancy

Pregnancy is the physiological condition in which a female carries and nurtures a developing embryo or fetus within her uterus. It typically lasts about 40 weeks, counted from the first day of the last menstrual period, and is divided into three trimesters. During pregnancy, the body undergoes significant hormonal, physical, and emotional changes to support the growth and development of the baby.

This condition begins with fertilization, when a sperm cell merges with an egg cell, leading to the formation of a zygote. As the zygote divides and develops, it becomes a blastocyst and eventually implants into the uterine wall. Throughout pregnancy, the developing fetus absorbs nutrients and oxygen through the placenta, which forms the lifeline between the mother and the fetus.

Pregnancy is marked by various stages and is associated with prenatal care to monitor the health of both the mother and the fetus. It culminates in childbirth, where the baby is delivered through vaginal birth or cesarean section. The experience of pregnancy can vary widely among individuals, influenced by various biological, psychological, and socio-cultural factors.
