Do snakes have hearts? | A Detailed Guide

Snakes are fascinating creatures that have intrigued humans for centuries.

Their unique characteristics, such as their ability to slither on their bellies and swallow prey whole, have earned them a reputation as both fearsome predators and intriguing pets.

However, many people wonder about one of the most basic aspects of snake anatomy: do snakes have hearts?

Do snakes have hearts?

Yes, snakes have hearts. Like all vertebrates, snakes have a circulatory system that includes a heart.

The heart of a snake is a muscular organ that pumps blood throughout its body, delivering oxygen and nutrients to its cells and removing waste products.

However, some interesting aspects of snake anatomy make their hearts slightly different from those of other animals.

Snake Heart Anatomy: how many hearts does a snake have

Snakes have a three-chambered heart, which is made up of two atria and one ventricle.

It is different from mammals and birds, which have four-chambered hearts.

In a snake’s heart, the two atria receive blood from different body parts and pump it into the ventricle, which then pumps the blood out to the rest of the body.

It means that oxygen-rich and oxygen-poor blood can mix in the ventricle, which is less efficient than the separate circulation of oxygen-rich and oxygen-poor blood in a four-chambered heart.

However, snakes have adapted to this less efficient system in other ways.

For example, they have a very slow metabolic rate compared to mammals and birds, requiring less oxygen.

They also have a specialized respiratory system that allows them to take in oxygen more efficiently through their skin and lungs.

Snake Heart Function

Like any other animal, a snake’s heart is crucial to its overall health and well-being.

The heart pumps blood throughout the body, delivering oxygen and nutrients to cells and tissues and carrying away waste products like carbon dioxide.

However, snakes have a slower metabolic rate and don’t require as much oxygen as other animals, so their heart rate is also much slower.

Some species of snakes have a resting heart rate as low as 10 beats per minute, compared to a human’s resting heart rate of around 60-100 beats per minute.

Interestingly, a snake’s heart rate can also vary depending on its activity level. When a snake is resting or sleeping, its heart rate will be much lower than when it is hunting or mating.

Snake Heart Health

Like any other organ, a snake’s heart can be affected by various health conditions. Some common issues that can affect snake heart health include heartworm disease, bacterial infections, and heart failure.

Symptoms of heart disease in snakes can include lethargy, decreased appetite, difficulty breathing, and abnormal heart sounds.

If you suspect your pet snake may be experiencing heart problems, it is important to seek veterinary care as soon as possible.

Where is the heart in a snake?

In snakes, the heart is located in the front portion of the body, just behind the head and in front of the lungs.

The exact position of the heart can vary slightly depending on the snake species, but it is generally located in the upper portion of the body.

The heart of a snake is a three-chambered organ consisting of two atria and one ventricle. The heart pumps oxygenated blood to the body and deoxygenated blood to the lungs for gas exchange.


What kind of heart do snakes have?

Snakes have a three-chambered heart consisting of two atria and one ventricle.

How does a snake’s heart work?

The atria of a snake’s heart receive blood from the body and the lungs, and then the ventricle pumps the blood out to the rest of the body.

Are there any medical uses for snake hearts?

While snake venom has been studied for its potential medical uses, snake hearts are not currently used for medical treatments.

Can snakes die from heart attacks?

While snakes can experience heart problems, such as arrhythmias, heart attacks are not a common cause of death in snakes.


Snakes do indeed have hearts, just like any other vertebrate animal. While their hearts differ slightly from those of mammals and birds, they play a crucial role in delivering oxygen and nutrients throughout the body and maintaining overall health and well-being.

As with any pet, it is important to monitor your snake’s health and seek veterinary care if you suspect any issues with its heart or other organs.
