How you were able to make sense out of what I typed (there I go assuming again ;-) is beyond me.
I just wanted to clarify a few things I posted...that may be misleading and submit page II that's right Page II!! (who's L their AO NOW!!) ahhh what a few hours sleep can do!!

>>>> I too used to advocate people soaking their iguana in Gatorade or Pedialyte to increase internal hydration...<<<<<<

Even if they don't absorb fluids at the vent..still a good idea if an ig is severely dehydrated because more than likely they will DRINK it! Added electrolytes etc still way better for em than plain ole water imo.

>>>>>. Dehydration is a very important factor....no doubt in preventing kidney disease<<<<
HUH??? I know you guys caught that one right!! LMAO
>>>>>...once ingested nutrients and liquids find way to cloaca were it is resorbed<<<<
Majority of fluids are absorbed by the large intestine....rest sent to the cloaca where it is pooled then reabsorbed as needed
>>>>>>kidney disease in our captive igs has more to do with the PROTEIN (plant) content of their foods/over supplementation of vitamins & the types of calcium given<<<<<<
Should be overall protein (plant or animal cept yogurt even that makes me wonder!) Also high dietary minerals like phosphorus, toxicants, nephotoxic medications, purines....blah blah blah...have an effect on their kids right. Am I boring you YET? lolol

Here are a few more snipets on water uptake/cloaca...but NO where do any of em talk about water uptake via the cloaca....And to answer T's "laymen" question....it appears the vent is EXIT ONLY!! Read a few things but didn't add them ....one talking about something similar to an anal sphinctor....(lololol) A Sphinctor says what? What? I sure am open (no pun) to anything that may state otherwise! Enemas excluded!

Don't ya think this makes for great bathroom reading! Am I the only one here that is this obsessive or igsane? Don't answer that!

Gina.....ducking the FEDS (sure Ive broken every copyright law on the books!) Im off to work pretty soon....you never saw me right!

*********************
Water Uptake in Reptiles Most reptiles obtain water primarily by drinking. In some case, food is also an important source. The other routes are minor in most cases.
Water Loss in Reptiles The greatest sources of water loss in reptiles are across the skin and respiratory surfaces, although a lot of variation is seen. Reptiles that live in dry habitats tend to have less permeable skin and dryer feces. Reptiles are capable of producing only an isosmotic urine (at best), but do use uric acid which saves on water loss by this route.
Salt Excretion in Reptiles Reptiles have an alternative mechanism for getting rid of salts. This is especially important in coastal and marine reptiles that ingest large quantities of salt in their diet, and in desert reptiles. These reptiles have specialized salt excreting glands in their nasal regions that can produce hyperosmotic salt concentrations (greater than their plasma).
******************
V. Osmotic Exchange in Terrestrial Animals

With the movement onto land comes new problems.

They still face a problem of ionic and osmotic exchange with the
environment - in this case an environment of much less water.

Thus the basic problem faced by terrestrial animals is water loss.

The water loss can occur:

Across the integument (evaporation)

Respiratory water loss

Urinary water loss

Fecal Water loss

Sources of water gain include:

Drinking

Feeding

Metabolic water

Uptake across integument
****************************
The class reptilla has over 7000 species including snakes, lizards, turtles, and crocodilians. All reptiles have scales with a waterproof coat of Keratin, which prevents the reptile from drying out. Because they cannot breathe through their dry skin they have to obtain all their oxygen through their lungs. Turtle use their cloaca for gas exchange.
*****************************
These vertebrates are cold blooded ( ectotherms )
Most of the water obtained by organisms is from food. Conserving precious water merits huge attention, as it is necessary for survival. Evaporative cooling is a source of major water loss in most desert animals. Mechanisms for restricting water loss during gas exchange include fused schlerites in insects, maxilloturbinals and nasal counterflow in mammals, and lowered transpiration rates in most animals. Insects expire in and out of the relatively cool abdomen rather than through the hot thorax to reduce evaporation. Integumentary water barriers such as scales, horny layers, thickened keratinized epidermis and epicuticular wax all work to reduce evaporation from the body surface (Hadley 1975). The hard shells of desert tortoises and turtles eliminate cutaneous water loss through evaporation (Stone 1989). The South American Ceratophyrd frog, a normally aquatic frog, forms a cocoon that is highly impermeable to water loss (Hadley 1975). Another source of water loss is excretion of metabolic wastes and salts. The highly concentrated urine of desert animals is produced by a complex series of physiological adaptations; however, one very important morphological adaptation to this is found in chuckwallas. Chuckwallas, a small lizard found in the Sahara, possess nasal salt glands that excrete about half of the dietary potassium and almost all of the chloride with very little loss of water. The rest of the potassium is excreted through the urine as a precipitate (Hadley 1975).
