Respiratory System . Snakes have a small opening just behind the tongue called the glottis, which opens into the trachea, or windpipe. Unlike what mammals have, the reptile glottis is always closed, forming a vertical slit, unless the snake takes a breath.
The posterior part is thin-walled and non-respiratory, mainly functions as an air sac and contains a major portion of the volume of the respiratory tract. In terrestrial snakes this air sac terminates in the intestinal mesentery near the gallbladder while in aquatic species it may reach to the cloaca and is thicker and more muscular.
Unlike the mammals,the snake's resp system contains a long right lung & a small left lung.The longer lung covers almost two third of the body.The shorter one is the rudimentary one.
An interesting fact that differentiates snakes from humans is that snakes, unlike humans, don't have a diaphragm. Also, humans have 2 fully developed lungs. Snakes generally only have one(the right), however some species have 2 or 4 lungs, a semi-developed lung (the left) and a pair of primordial tracheal lungs (located beside the throat).
Respiratory System For Snakes: Every animal needs to take in oxygen, it is part of their cellular respiration. Cellular respiration is a way that cells obtain energy. What happens in this process is that the cells burn glucose (sugar) to make ATP (stored energy). ATP stands for adenosine triphosphate.
Snakes have both renal and hepatic portal circluations. Jugulars are located anterior to the heart near the trachea and may be cannulated by a cutdown procedure. The right jugular is larger than the left. Blood returns to the heart from the systemic circulation through the sinus venosus. Find out more about the snake respiratory system.

Respiratory system: Respiratory system, the system in living organisms that takes up oxygen and discharges carbon dioxide in order to satisfy energy requirements. In the living organism, energy is liberated, along with carbon dioxide, through the oxidation of molecules containing carbon.
Reptiles' lungs are the main component of their respiratory system, just as they are in humans, birds and land-dwelling amphibians. However, among the main types of reptiles, there are some distinct differences in the details of their respiratory system functioning. Regardless of the differences ...
