Build Your Own Systems Map

Turn your textbook chapter or lecture notes into a clear map of how breathing and blood flow connect.

Start from your own material

Upload a PDF, Word file, PowerPoint or text notes, and the AI extracts the key organs and processes.

Expand any branch

Open a node like gas exchange or pulmonary circulation and let the AI add the detail you need.

Quiz yourself from the map

Turn the finished map into a quiz, or make flashcards from the same notes before your exam.

How to Make Your Systems Map

Three steps from your notes to a study map of both systems.

  1. 1

    Add your notes or topic

    Upload your chapter, slides or image, or type respiratory and circulatory systems.

  2. 2

    AI builds the map

    The AI groups organs, gas exchange and blood circulation into linked branches.

  3. 3

    Study, expand and quiz

    Edit nodes, expand weak areas, then export as PNG or PDF or test yourself.

Respiratory and Circulatory Systems Explained

A concept map of the respiratory and circulatory system links two systems that work together. The respiratory system brings oxygen into the body and removes carbon dioxide, while the circulatory system carries those gases through the blood. Both depend on the heart, lungs and blood vessels to keep cells supplied.

  • Respiratory tract: nose, pharynx, larynx, trachea, bronchi
  • Lungs and alveoli: where gas exchange happens
  • Heart chambers: two pumps working in series
  • Pulmonary circulation: blood flow between heart and lungs
  • Systemic circulation: blood flow to the body's tissues

Use a map like this to revise how oxygen travels from air to tissues. Then generate a version from your own notes with CogniGuide, so the branches match your course.

Questions About Systems Maps

Common questions about the topic and about building your own map.

What is the difference between pulmonary and systemic circulation?

Pulmonary circulation moves deoxygenated blood from the heart to the lungs and back. Systemic circulation carries oxygen-rich blood from the left side of the heart to the body and returns it to the right side.

How does gas exchange happen in the lungs?

Oxygen diffuses from alveoli into surrounding capillaries, and carbon dioxide diffuses the other way. The thin walls of alveoli and capillaries make this exchange efficient.

Which files can I use to build this map?

You can upload PDF, Word (DOCX), PowerPoint (PPTX), text or Markdown files, or images. You can also type a topic directly.

Can I turn the map into a quiz?

Yes. Once your map is built, you can turn it into a quiz to test yourself on both systems.
