What are the basic physiological functions of the kidneys?
The kidneys are powerful chemical factories that perform the following functions:
- remove waste products from the body.
- remove drugs from the body.
- balance the body’s fluids.
- release hormones that regulate blood pressure.
- produce an active form of vitamin D that promotes strong, healthy bones.
What are the four functions of the kidneys?
Their basic functions include:
- Regulation of extracellular fluid volume. The kidneys work to ensure an adequate quantity of plasma to keep blood flowing to vital organs.
- Regulation of osmolarity.
- Regulation of ion concentrations.
- Regulation of pH.
- Excretion of wastes and toxins.
- Production of hormones.
Which important function does the kidney perform?

Which is the functional unit of the kidney?
Here’s a summary of kidney structure and function based on different parts of the kidney: The Functional Unit of Kidney: Nephron The nephron is the kidney’s functional unit that removes waste from the body. Each kidney has more than a million nephrons in the renal cortex, which gives it a granular appearance on sagittal section.
How are the kidneys involved in the urinary system?
The renal vein exits each kidney to join the inferior vena cava, which transports blood back to your heart. The urinary system depends on proper kidney structure and function. Some of these core actions include: Excretes waste: The kidneys get rid of toxins, urea, andexcess salts.
