About these human body worksheets

Your body is a team of systems. Bones hold you up, muscles pull on them to move you, the lungs bring in oxygen, the heart pumps it around in the blood, the digestive system turns food into nutrients, and the brain and nerves run the whole show.

These human body worksheets build up by grade. Third graders meet the main organs and what they do. Fourth graders label the skeleton, see how muscles work in pairs, sort organs into body systems and trace messages through the nervous system. Fifth graders label the digestive and respiratory systems, follow the path of food, read about the heart and blood vessels and use pulse data to see how the body responds to exercise.

Every diagram is drawn from the front, in black and white, with a labeled version, a version with a word bank and, for the big diagrams, a cut and paste version with a no-scissors twin. Pages with right answers have an answer key on page 2.

Standards

  • NGSS 4-LS1-1Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.
  • NGSS 4-LS1-2Use a model to describe that animals receive different types of information through their senses, process the information in their brain, and respond to the information in different ways.
  • CCSS.ELA-LITERACY.RI.3.7Use information gained from illustrations (e.g., maps, photographs) and the words in a text to demonstrate understanding of the text (e.g., where, when, why, and how key events occur).
  • CCSS.ELA-LITERACY.RI.5.3Explain the relationships or interactions between two or more individuals, events, ideas, or concepts in a historical, scientific, or technical text based on specific information in the text.
  • CCSS.ELA-LITERACY.RI.5.4Determine the meaning of general academic and domain-specific words and phrases in a text relevant to a grade 5 topic or subject area.

How to use them

  1. Start with the labeled diagram or the body systems chart. Point to each part on your own body as you read its job.
  2. Use the label it page next, then the cut and paste version for a hands-on review.
  3. Before the heart rate page, have children find their pulse on the neck or wrist and count it for a minute.
  4. Finish with the reading passage or the vocabulary page to check understanding.

Teaching tips

  • The diagrams face you, so the person's left side is on the right of the page. The heart sits a little to the person's left.
  • Muscles can only pull. That's why they work in pairs: one bends a joint and the other straightens it.
  • The liver is part of the digestive system, but food does not pass through it. It makes bile, which helps break down fat.
  • The pulse data are made-up practice numbers and are labeled that way on the page.

Questions teachers and parents ask

What are the main systems of the human body?

Kids usually learn six: skeletal (bones), muscular (muscles), digestive (food), respiratory (breathing), circulatory (heart and blood) and nervous (brain and nerves). They all work together.

How many bones are in the human body?

An adult has about 206 bones. Babies are born with more, and some of them grow together as they get older. The femur, or thigh bone, is the longest.

Why do muscles work in pairs?

A muscle can only pull, not push. To bend your elbow the biceps contracts; to straighten it the triceps contracts. One muscle in the pair relaxes while the other pulls.

What is the path of food through the body?

Mouth, esophagus, stomach, small intestine and large intestine. Nutrients pass into the blood in the small intestine, and the large intestine takes back water.
