Excretory System in Frog -
Excretory System in Frog
- The elimination of nitrogenous wastes is carried out by a well-developed excretory system.
- The excretory system consists of a pair of kidneys, ureters, cloaca and urinary bladder.
- Kidneys are compact, dark red and bean like structures situated a little posteriorly in the body cavity on both sides of the vertebral column.
- Each kidney is composed of several structural and functional units called uriniferous tubules or nephrons.
- Two ureters emerge from the kidneys in the male frogs. The ureters act as urinogenital duct which opens into the cloaca.
- In females the ureters and oviduct open separately in the cloaca.
- The thin-walled urinary bladder is present ventral to the rectum which also opens in the cloaca.
- The frog excretes urea and thus is a ureotelic animal.
- Excretory wastes are carried by the blood into the kidney where it is separated and excreted.
-
