Injecting lizards with nephrotoxic drugs could potentially result in increased renal toxicity because...?

Please select an option Incorrect! Lizards do indeed have a three chambered heart; however this does not explain the increased renal toxicity. The reason is that reptiles have a renal portal system where venous return from the tail and hindlimbs may be filtered through the kidneys to bathe the renal tubules. Therefore the injection of drugs that are cleared via tubular excretion into the caudal half of the body could result in lower than anticipated serum concentration because of their excretion in the urine before entering the systemic circulation. WikiVet Article: Lizard Cardiovascular System Incorrect! Reptiles have a renal portal system where venous return from the tail and hindlimbs may be filtered through the kidneys to bathe the renal tubules. WikiVet Article: Lizard Cardiovascular System Incorrect! The reason is that reptiles have a renal portal system where venous return from the tail and hindlimbs may be filtered through the kidneys to bathe the renal tubules. Therefore the injection of drugs that are cleared via tubular excretion into the caudal half of the body could result in lower than anticipated serum concentration because of their excretion in the urine before entering the systemic circulation. WikiVet Article: Lizard Cardiovascular System Incorrect! Reptiles have a renal portal system where venous return from the tail and hindlimbs may be filtered through the liver. WikiVet Article: Lizard Cardiovascular System Correct! Reptiles have a renal portal system where venous return from the tail and hindlimbs may be filtered through the kidneys to bathe the renal tubules. Venous return may also be filtered through the liver. Therefore the injection of drugs that are cleared via tubular excretion into the caudal half of the body could result in lower than anticipated serum concentration because of their excretion in the urine before entering the systemic circulation.WikiVet Article: Lizard Cardiovascular System

What anatomical characteristic is specific to lizards capable of autotomy?

Please select an option Incorrect! Lizards that are capable of autotomy have a vertical fracture plane through the body and part of the neural arch of the tail vertebrae. WikiVet Article: Lizard Musculoskeletal System. Incorrect! Lizards that are capable of autotomy have a vertical fracture plane through the body and part of the neural arch of the tail vertebrae. WikiVet Article: Lizard Musculoskeletal System. Correct! Lizards that are capable of autotomy have a vertical fracture plane through the body and part of the neural arch of the tail vertebrae. WikiVet Article: Lizard Musculoskeletal System. Incorrect! Like other reptiles, lizards have a single occiptal condyle. This characteristic isn't specific to lizards capabale of autotomy. WikiVet Article: Lizard Musculoskeletal System. Incorrect! Ribs are present on all vertebrae except tail and cervical vertebrae. WikiVet Article: Lizard Musculoskeletal System.

In lizards, what is the proctodeum?

Please select an option Incorrect! The ureodeum is the part of the cloaca which collects urinary wastage. WikiVet Article: Lizard Gastrointestinal System Correct! The proctodeum is the final chamber of the cloaca, prior to elimination. WikiVet Article: Lizard Gastrointestinal System Incorrect! The coprodeum is the part of cloaca which collects faeces. WikiVet Article: Lizard Gastrointestinal System Incorrect! A caecum is present in many lizard species. WikiVet Article: Lizard Gastrointestinal System Incorrect! The vent is the external opening of the cloaca. The proctodeum is the final chamber of the cloaca, prior to elimination. WikiVet Article: Lizard Gastrointestinal System
