Which urinary system structure is considered the functional unit responsible for filtration and water absorption?
a. Collecting duct
b. Ureter
c. Nephron
d. Tubular system
C
The nephron is the basic structural and functional unit of the kidney. The collecting duct, ureter, and tubular system are all incorrect because they are not the basic structural and functional unit, but are merely a part of it. Each nephron consists of a Bowman's capsule, enclosing a glomerulus (responsible for most of filtering), a series of filtrating tubules and a collecting duct. Together, these structures act as a microscopic filter, controlling the excretion and retention of fluids and solutes according to the body's moment-by-moment needs.
