Where Is A Snake’s Heart?

Hearts of snakes are located between 15% and 25% of their body length from their head. Different snakes have different positions of their hearts; some have them further or closer to their heads. Additionally, snakes’ hearts don’t remain stationary, as they move when they move.

A lot of factors can change the position of the snake’s heart, such as habitat and size. Many snakes have their hearts closer when they are arboreal (live in trees), and further when they are terrestrial (live on land). However, there has been no accurate scientific explanation as to why this phenomenon exists; it has only been observed.

Larger snakes also tend to have hearts that are further from their heads, since they need to distribute blood farther than smaller snakes. The heart tends to move when snakes slither around. It is also found that this also helps in the distribution of blood to the body as the heart does not remain in one place.

What Is the Structure of a Snake’s Heart?

A snake’s heart has three chambers, consisting of two atria and a single ventricle. The atria receive blood from the lungs and the body, while the sole ventricle is the one that pumps out blood into the arteries.

However, the heart isn’t the only system involved in the circulatory system of a snake. The heart is connected to the rest of the body by arteries and veins, which help transport blood throughout the body. Snakes also have the Renal Portal system, in which the blood passes through the kidneys.

What Is the Renal Portal System?

The Renal Portal System is a specialized circulatory system that is unique to reptiles. This system allows the kidneys and other organs to receive large amounts of blood, which helps them function properly. The Renal Portal System consists of a vein that branches off from the tail and then enters the snake’s kidney. From there, it travels through several lymph nodes before ending up in another vein that leads to the heart. This unique circulatory system helps keep snakes functioning properly even in harsh environmental conditions.


The location of a snake’s heart can vary from 15% to 25% of the body’s length from the head, depending on factors such as habitat and size. The heart itself is made up of three chambers: two atria and a single ventricle. Additionally, another system in snakes, the Renal Portal System, helps to distribute blood to the rest of the body.
