If my science book proves correct, I believe it is so the O2 rich blood and the O2 poor blood mixing is kept to a minimum.
In most reptiles there are 2 atriums and 1 ventricle, it also has 3 heart chambers
One key difference is that mammal hearts have four chambers (two atria and two ventricles) while reptile hearts typically have three chambers (two atria and one ventricle). Mammals have a double circulatory system (systemic and pulmonary circulation) while reptiles have a single circulatory system.
Crocodylians, such as alligators, crocodiles, caimans, etc, have four chambered hearts. Testudinidae (turtles), Squamata (amphisbaenians (lizard like), lizards, and snakes), Rhynchocephalia (tuataras); all have two chambered hearts. Hope this helps :)
Fish have two chambers (one atrium and one ventricle), amphibians have three chambers (two atria and one ventricle), while mammals have four chambers (two atria and two ventricles). This difference in chamber arrangement affects the efficiency of oxygenated and deoxygenated blood separation within the circulatory system.
Yes, a fish has two heart chambers, the atrium and the ventricle. The atrium serves as a one-way compartment for blood to flow into the ventricle and the ventricle pumps the blood through the fish
In turtles, the heart has two atria and a single ventricle partially divided by a wall of tissue called a septum. In crocodiles, there are two atria and two separate ventricle.

It is the ventricle
Ventricle. It's a single ventricle heart.
left ventricle
A brown snake is a reptile, so it has a closed circulatory system. Reptiles have a three-chambered heart composed of two atria and one ventricle.
The lower chambers of the heart are the left ventricle and the right ventricle.
The right ventricle pumps blood from the heart to the lungs and back to the heart
Oxygenated blood is pumped out of the heart by the left ventricle.
The left ventricle and the right ventricle. In a human, the heart is tilted in such a way that the right ventricle is closer to the chest, and the left ventricle is behind it.
