Uterus facts for kids
The uterus, also known as the womb, is an amazing organ found in the female body. It's shaped like a pear and is where a baby grows and develops for about nine months during pregnancy. The uterus is located in the lower part of a female's belly, nestled between the hips, just below the fallopian tubes. When we talk about more than one uterus, we call them 'uteri'.

What is the Uterus?
The uterus is a hollow, muscular organ that plays a super important role in reproduction. Think of it as a cozy, safe home for a growing baby. It's incredibly strong and can stretch a lot to make space as the baby gets bigger.
Where is the Uterus Located?
The uterus sits in the pelvis, which is the lower part of your body. It's behind the bladder (where pee is stored) and in front of the rectum (the last part of the large intestine). Its position helps protect it and the baby inside.
How Does the Uterus Work?
Every month, if a female is not pregnant, the lining of the uterus gets thicker and fills with blood and nutrients. This is to prepare a soft bed for a possible fertilized egg. If an egg isn't fertilized, this lining isn't needed, and it sheds during a period, which is called menstruation.
If an egg is fertilized by sperm, it travels down the fallopian tube and attaches itself to this thick uterine lining. This is when pregnancy begins! The uterus then becomes the baby's home for the next nine months.
The Uterus During Pregnancy
During pregnancy, the uterus grows a lot. It starts about the size of a pear but can expand to be as big as a watermelon by the end of pregnancy! This incredible growth happens because the muscle fibers in the uterus stretch and multiply.
The uterus also has a very important job during childbirth. When it's time for the baby to be born, the strong muscles of the uterus start to contract. These contractions help push the baby out through the vagina.
Parts of the Uterus
The uterus has a few main parts, each with its own job:
- Fundus: This is the top, rounded part of the uterus, above where the fallopian tubes connect.
- Body (Corpus): This is the main, largest part of the uterus, where the baby grows.
- Cervix: This is the narrow, lower part of the uterus that connects to the vagina. It acts like a strong, muscular gate, keeping the baby safe inside during pregnancy and opening up during childbirth.
Keeping the Uterus Healthy
Taking care of your body, including your uterus, is important for overall health. Eating healthy foods, staying active, and having regular check-ups with a doctor can help keep your reproductive system healthy.
