Question

How many heart chambers are in a snake's heart?

Answer 1

Hint: A snake belongs to the class reptilia of kingdom Animalia and phylum Chordata and the heart of the snake is similar to that of the other reptiles.

Complete answer:
1)The position of the heart is not fixed in all the snakes as it is not supported by the diaphragm and is freely located within the ribcage of the snake. Huge prey can be easily engulfed by the snake because it can easily move its heart within the rib cage.
2)The heart of snakes has only three chambers, it consists of two auricles or atrium that are the left atrium and the right atrium, and only one ventricle.
3)The right auricle of the snake's heart receives impure deoxygenated blood from the entire body of the snake whereas the left auricle receives the pure oxygenated blood from the lungs of the snake through the pulmonary veins.
4)There is only one ventricle in the heart of the snake but there is a small crest in the ventricle that separates the pure oxygenated blood and the impure deoxygenated blood.
5)Therefore, there are three chambers in the snake's heart.

Note: The ventricular of the snake's heart is divided into further three sub-chambers that are known as cavum venosum, cavum arteriole, and cavum pulmonale. The heart of the snake also has two aortae, one is the right aorta that extends from the left ventricle, and the other is the left aorta that extends from the right ventricle of the snake's heart.
