The cardiovascular system of snakes is unique for the presence of a renal portal system in which the blood from the snake's tail passes through the kidneys before returning to the heart. [79] The circulatory system of a snake is basically like those of any other vertebrae. However, snakes do not regulate internally the temperature of their blood.
The thermal radiation above a given threshold causes an increase in the temperature of the nerve fiber, resulting in stimulation of the nerve and subsequent firing, with increased temperature resulting in increased firing rate. [10] The sensitivity of the nerve fibers is estimated to be <0.001 °C. [11]
An ectotherm (from Ancient Greek ἐκτός (ektós) ' outside ' and θερμός (thermós) ' heat '), more commonly referred to as a "cold-blooded animal", [1] is an animal in which internal physiological sources of heat, such as blood, are of relatively small or of quite negligible importance in controlling body temperature. [2]
For a better understanding, “cold-blooded actually means the animal’s body temperature is basically the same as its surroundings,” according to Texas Parks & Wildlife. “A fish swimming in ...

The skin of snakes is highly sensitive to contact, tension, and pressure; they are capable of feeling pain. [67] An important function of the skin is the sensation of changes in air temperature, which can guide the snakes towards warm basking/shelter locations. [68] All snakes are ectotherms. To maintain a stable body temperature, they exchange ...
Thermographic image: a cold-blooded snake is shown eating a warm-blooded mouse. Warm-blooded is a term referring to animal species whose bodies maintain a temperature higher than that of their environment. In particular, homeothermic species (including birds and mammals) maintain a stable body temperature by regulating metabolic processes.
