Free Respiratory System Labeling Worksheet

This respiratory system labeling worksheet is a simple and visual way to introduce kids to basic human anatomy.

We used it during a quick health unit in 3rd grade, and it helped my son easily connect each part of the system, like the nose, lungs, and trachea, to what he already knew about breathing.

It’s a great starting point for younger learners who need something hands-on and straightforward, especially if you’re not diving into full science lessons yet.

What’s Included in This Respiratory System Labeling Worksheet

This free anatomy worksheet comes with two pages:

• Page 1: A simple diagram of the respiratory system with arrows pointing to five key parts, nose, mouth, larynx, trachea, and lungs. A word bank is included to help kids match each term to the correct location.
• Page 2: A completed version with all parts labeled, so kids can check their work or use it as a reference.

The layout is clear and kid-friendly, making it easy for elementary students to complete independently. It’s best suited for grades 3–5, but could be adapted for younger or older kids depending on how you introduce the topic.

How to Use It

This worksheet works well as part of a human body science unit or as a quick health lesson.

You can introduce the five parts of the respiratory system first using books or a short video, then have kids label the diagram using the word bank.

I found it helpful to let my son color the parts afterward, which helped reinforce each term. The answer sheet makes it easy to check work or support younger learners who need a little extra help.

What Is the Respiratory System?

Before labeling each part, it helps to understand what the respiratory system actually does. Here’s a quick overview of how it works and what each part is responsible for.

The Nose

Air enters the body through the nose, where it gets filtered by tiny hairs (cilia) and warmed by mucus. This helps protect the lungs from dust and germs.

The Mouth

The mouth can also bring air into the body, but it doesn’t filter or warm it the way the nose does. It’s often used for breathing during exercise or when the nose is blocked.

The Larynx

Also called the voice box, the larynx helps us speak and make sounds. It sits just above the trachea and contains the vocal cords.

The Trachea

The trachea, or windpipe, is a tube that connects the larynx to the lungs. It carries air in and out and stays open with the help of strong cartilage rings.

The Lungs

The lungs are two soft organs where gas exchange happens. They bring oxygen into the blood and remove carbon dioxide when we exhale.

Pair this with our free human body systems worksheet PDF, which gives kids a broader look at how the major systems, like circulatory, digestive, and nervous, work together. Great for review or introducing anatomy as a whole.

Human Biology Books We’ve Actually Used

Books have always been a big part of how we learn, and when we were exploring the human body, these really stood out. They weren’t just educational, they were the ones my son actually wanted to read, flip through, and ask questions about.

Know Yourself has been one of our favorites for years. The mix of comics, activities, and facts makes it fun without feeling like schoolwork. If you’re using my link, they’re currently offering 15% off.

Human Anatomy for Kids is a solid pick if you want clear explanations and colorful visuals. It covers everything from bones to organs in a way that’s easy to follow but still packed with detail.

How Does My Body Work? was a hit in our house because of the hands-on STEAM activities. It’s great for kids who like building, testing, and trying things out, it goes beyond just reading.

Ultimate Bodypedia is the one we reach for when we want to go deeper. It’s packed with diagrams, real photos, and quick facts that even I found fascinating. It covers more than just the respiratory system, so it’s one we keep coming back to.

If you’re building out a unit on the human body or just want something your child can explore independently, these are the books I’d personally recommend.

If your kids enjoy labeling worksheets, they’ll love our free body systems word search, a fun way to reinforce vocabulary like lungs, trachea, and more.
