Bird anatomy, or the physiological structure of birds' bodies, shows many unique adaptations, mostly aiding flight.Birds have a light skeletal system and light but powerful musculature which, along with circulatory and respiratory systems capable of very high metabolic rates and oxygen supply, permit the bird to fly.
A favorable outcome is more likely if a kidney transplant is complemented by a liver transplant, given the disease originates in the liver. [ citation needed ] Secondary hyperoxaluria is much more common than primary hyperoxaluria, and should be treated by limiting dietary oxalate and providing calcium supplementation.
Filtration of the blood, reabsorption of ions and water, and secretion of uric acid are all components of the kidney's process. Columba livia has two kidneys that are coupled, each having three partially separate lobes; the posterior lobe is the largest in size. Like mammalian kidneys, the avian kidney contains a medullary region and a cortical ...
Birds have small glomeruli, but about twice as many nephrons as similarly sized mammals. [47] The human kidney is fairly typical of that of mammals. Distinctive features of the mammalian kidney, in comparison with that of other vertebrates, include the presence of the renal pelvis and renal pyramids and a clearly distinguishable cortex and medulla.
Hornbills have a two-lobed kidney. They are the only birds in which the first and second neck vertebrae (the atlas and axis respectively) are fused together; this probably provides a more stable platform for carrying the bill. [1] The family is omnivorous, feeding on fruit and small animals.

The mesonephros (Greek: middle kidney) is one of three excretory organs that develop in vertebrates. It serves as the main excretory organ of aquatic vertebrates and as a temporary kidney in reptiles, birds, and mammals. The mesonephros is included in the Wolffian body after Caspar Friedrich Wolff who described it in 1759. (The Wolffian body is ...
