Transcript of Digestive System of a Snake ~~~~

Yuhei, Daniel and Daryl Digestive System of a SNAKE Excretion How do snakes eat their prey? A snake excretes its wastes through an anal scale which covers it's cloaca. when the snake takes a no.2 the feces are hard because the cloaca obsorbs all the moisture.the poop is mostly compiled of a chunk of the unwanted parts of their meal, but the snake wants to conserve as much water as possible so instead of peeing it obsorbs all the posture fron the urine ans excretes the acids in the urine.the snake ensure it uses the littlest amount of water to excrete is waste. the snakes organs The small intestine is a long narrow coilted tube where the absorption of nutrients takes place. The small intestine is divided into three regions: the duodenum, the ileum, and jejunum. The rate of digestion depends on the body temperature of the snake. The large intestine is the least muscular and most thin-walled structure of the snakes digestive system. The small and large Intestine The Oesohpagus of a snake is thinly muscled but is quite flexible to accommodate relatively large prey. The stomach is a j-shaped organ is not very advanced and is not well defined. It is short and has many folds to increase the surface area for digestion and absorption. Oesophagus and Stomach A mouth of a snake is highly expandable and flexible allowing them to swallow prey much larger than their head.When swallowing prey all snakes eat their prey headfirst, it makes the swallowing of limbs so much easier.
The bottom jaw is separated so it is in two peices, this allows the snake to extend its mouth really far. INTERESTING FACTS -Snakes can consume prey that are 50-160% bigger than their size! -Digesting prey is a race agaisnt time because if it takes too long the animal will rot and the snake will need to regurgitate its prey. the snake heart is contained in a sac called the pericardium.the left lung of a snake is usually small or they dont even have a left lung,because of their slender bodiestheir organs have to be a thin as possible.some of their organs are paired but one is ussualy ahead of one another.also snakes have no lymph nodes.the snakes heart is able to move around this allows the snake to protect its heart fron some potentional threat if attacked near is heart. -the venom in some snake like the cobra or viper is just some modified siliva. -recently it has been confirmed that some species of snake are vivaporouse, which means they keep their eggs untill their mnearly going to hatch, this is very unusual.
