Explaining Biology on Instagram: "This is what the bottom of the vaginal canal looks like — the cervix. The cervix is the small, donut-shaped opening at the end of the vagina. It’s part of the uterus and plays an important role in reproductive health. A healthy cervix typically appears smooth, pink, and moist. Its appearance can naturally change throughout your menstrual cycle, pregnancy, or due to hormonal shifts. Regular check-ups and Pap smears help keep your cervical health on track. DM FOR
