What is a Heart Diagram?

The heart is one of the most important organs in the human body, and every undergraduate anatomy course will undoubtedly include a section on cardiovascular anatomy or physiology.

The flow of blood through the heart and the associated anatomical structures that move blood through the chambers of the heart are fundamental concepts for students of medicine, nursing, anatomy, or other health professions. 

A Heart Diagram is a visual depiction of the heart designed to convey anatomical or physiological features in a simplified way. This could be depicting the coronary circulation, the layers of the heart, the electrical conduction pathways of the heart, or just the heart’s basic structure. 

To help you wrap your head around the basic anatomy of the heart, we have developed this Heart Diagram that sets out key anatomical features of the heart in a simple and accessible way.

Utilize this diagram in your studies by covering up the labels or unwinding by coloring in the different parts of the heart. Either way, this diagram can be a great resource for familiarizing you or your students with heart anatomy.

When are the best times to use this Heart Diagram template?

Lecture revision

Getting comfortable with the basic anatomy of the heart is crucial for many university courses such as nursing, medicine, or anatomy. This diagram can serve as a visual reference for your study, helping to provide some variety for your study resources. 

Exam or test prep

Use this diagram as preparation for an upcoming exam or test by ensuring you can name all the labeled structures of the heart and adding in any extra structures such as layers of the heart wall, branches of the aorta, or the direction of blood flow through the chambers of the heart (see our example diagram above for the correct answer for this last point!). 

Mindful coloring 

Coloring is a great way to unwind and get creative without too much effort. If you’ve studied to maximum capacity, why not relax with our Heart Diagram and peacefully revise as you color? 

Revision for cardiology rotations

If you’re already out of nursing or medical school but just need a quick refresher, this diagram can be a great go-to revision resource. It sets out the most important anatomical structures and can be annotated with any additional points you need to know before going into a cardiology rotation. 

Educational resource for patients or students

This resource isn’t just for students, and clinicians can use this diagram to educate their patients on simple cardiovascular anatomy to help them understand relevant conditions. This free resource can also be used by academics, lecturers, or tutors to provide to their own students. 

What are the benefits of using a Heart Diagram?

Simple design

The simple design of this human heart diagram allows for the revision of the core concepts of cardiovascular anatomy before adding in more complicated steps such as electrophysiology or coronary circulation. This simplifies explaining the anatomy of the heart to your patients and ensures they can understand the key points. 

Focus on basic anatomy

We must crawl before we can walk, so before you can move onto more advanced topics in cardiovascular anatomy and physiology, you must know the basic anatomy, like the back of your hand. This diagram includes just the basic structures but can easily be annotated with additional details as you progress.


For some more creatively inclined students, coloring isn’t just a hobby- it can be a great revision practice. By engaging with this diagram by annotating, coloring, and adding extra labels- you’ll improve memory retention and have a fun time while doing it!

Space for additional notes

Given the simple nature of this diagram, you’ll likely have some extra notes to add, and we have provided space in this diagram for you to do so. Whether this is to summarize your notes in words or answer some practice questions.

Commonly asked questions

How can heart diagrams be used to aid anatomy study?

Heart diagrams are valuable tools for studying anatomy as they visually represent the complex structure of the heart, illustrating the position and relationships of its various components, such as chambers, valves, and major blood vessels. This aids learners in understanding the three-dimensional nature of the heart and its functions.

What is the use of heart diagrams in a clinical setting?

In a clinical setting, heart diagrams serve as effective communication aids between healthcare professionals and patients, helping to explain medical conditions, treatment plans, and surgical procedures related to the cardiovascular system. They enhance patient education and facilitate clearer discussions about cardiac health.

Are there different types of heart diagrams?

Yes, there are different heart diagrams, ranging from simple illustrations for educational purposes to more detailed diagrams used in medical textbooks or presentations. Some diagrams focus on specific aspects, such as blood flow or cardiac conduction, providing targeted insights into different facets of heart anatomy and function.
