1. Sperm and Egg: It starts with a male sperm cell and a female egg cell.
2. Fertilization: The sperm cell travels through the female reproductive system and fertilizes the egg cell. This means the sperm and egg combine to form a single cell called a zygote.
3. Development: The zygote begins to divide and grow, eventually forming a baby within the mother's womb (uterus). This process takes about nine months.
4. Birth: After about 40 weeks, the baby is born through a process called labor and delivery.
Important Note: This is a very simplified explanation. The process of human reproduction is incredibly complex and involves many different hormones, organs, and systems.
