Human body systems template

This human body systems template helps students explore four major systems of the human body: the respiratory, digestive, nervous, and circulatory systems. Each system includes a short explanation and guiding questions that help students identify the key organs and structures involved and describe their roles.

Use this interactive worksheet in science and biology lessons to review how the body breathes, digests food, sends signals, and transports blood. Students complete the answer topics, follow the path of air, food, and blood through the body, and build a clear visual summary they can use for revision or class discussion.

Human Body Systems

Circulatory system

The circulatory system transports blood around the body, delivering oxygen and nutrients and carrying away carbon dioxide and other waste products.

Use the three “add answer” inputs to identify its main components. Think about what pumps, what flows, and what provides the pathways. Briefly describe how each component helps transport substances.

Nervous system

The nervous system receives information, processes it, and sends signals that coordinate the body’s responses.

Use the two “add answer” inputs to identify its two main divisions. For each division, name the structures it includes and briefly explain its role. Think about how information travels between the body and its control centre.

Digestive system

The digestive system breaks food down so the body can absorb nutrients. It also helps eliminate undigested waste.

Complete the four “add answer” inputs with important digestive organs. Follow the journey of food through the body and briefly explain what happens at each organ you choose.

Respiratory system

The respiratory system brings oxygen into the body and removes carbon dioxide.

Complete the four “add answer” inputs with important organs or structures involved in breathing. Think about the route air takes into the lungs and the muscles that help you breathe. For each answer, briefly describe its role.
