nephron
avian kidneys function in almost the same way as the more extensively studied mammalian kidney, but with a few important adaptations; while much of the anatomy remains unchanged in design, some important modifications have occurred during their evolution. a bird has paired kidneys which are connected to the lower gastrointestinal tract through the ureters. depending on the bird species, the cortex makes up around 71-80% of the kidney's mass, while the medulla is much smaller at about 5-15% of the mass. blood vessels and other tubes make up the remaining mass. unique to birds is the presence of two different types of nephrons (the functional unit of the kidney) both reptilian-like nephrons located in the cortex and mammalian-like nephrons located in the medulla. reptilian nephrons are more abundant but lack the distinctive loops of henle seen in mammals. the urine collected by the kidney is emptied into the cloaca through the ureters and then to the colon by reverse peristalsis.

bullet::::- the functional unit, which defines what precisely is being studied and quantifies the service delivered by the product system, providing a reference to which the inputs and outputs can be related. further, the functional unit is an important basis that enables alternative goods, or services, to be compared and analyzed. so to explain this a functional system which is inputs, processes and outputs contains a functional unit, that fulfills a function, for example paint is covering a wall, making a functional unit of 1m² covered for 10 years. the functional flow would be the items necessary for that function, so this would be a brush, tin of paint and the paint itself.
