Blog #1: Guide to the Gram Project

The use of diagrams and flowcharts is an extremely efficient and simple way to learn medical concepts. As medical students, we have always found these visual guides helpful in understanding and remembering challenging topics which we would otherwise have to read through a wall of text for. Here at the Gram Project, we aim to have a collection of easy to use medical diagrams for understanding, teaching and revising certain concepts of medicine. 

As of writing this blog, we have 5 main categories – physiology, interpretation, medicine, surgery and pharmacology, although we have plans to add more in the future. New diagrams are constantly being added, and we gladly welcome any suggestions for new content. We strive to ensure that our diagrams are as accurate as possible, with references listed in the download page of each diagram. However, should you encounter any errors in our diagrams, feel free to contact us here or email us at

Using the

The easiest way to use this website is to search for the diagram you are looking for using the search bar in our homepage, or by clicking on the search icon on the top right corner of the site. Alternatively, you can browse our catalogue of physiology, medical and surgical diagrams. Clicking on the left zoom button on a diagram will give you a full-sized preview of the image, while clicking on the right download button will bring you to its download page.

Interpreting the diagrams

Our diagrams flow from either top to bottom or from left to right. We try to colour code our diagrams as much as possible – look for a blue box as that is usually the start of the flowchart. Steps in the flowchart are either in yellow or orange. Lastly, as a general rule, a positive outcome of the diagram will be in a green box, while a negative outcome will be in a red box.

Use of diagrams

All our diagrams are free to use, distribute and alter for any purpose. All we ask for is proper attribution to our website at
