THE DISTRIBUTION OF NITROGEN IN THE BLOOD AND URINE OF THE TURTLE (CHRYSEMYS PINTA)

Abstract

Analyses of the blood, urine, and tissues of the turtle (Chrysemys picta) are reported. With regard to the N metabolism, these reptiles are intermediate between the reptiles of the arid regions (snakes, lizards) and the mammals; they excrete considerable amounts of both urea and uric acid.
