2015
Bianca Matosz | V. E. Luca
The snake has evolved its body for crawling so has few external features. Elongation has also resulted in asymmetry of viscera with right-sided organs lying cranial to and being larger than left. To explain the location of organs more easily, it is best to divide the length of the snake into three regions. The cranial region has the heart, trachea, esophagus, thyroid and proximal lung. The middle region has the stomach, liver, lung, spleen, and pancreas. The caudal region has the small and large intestines, kidneys and gonads. The gall bladder lies near the pylorus of the stomach and is located some distance from the posterior pole of the liver.
