Study Notes
Kidney Function
- The main function of the kidneys is to filter waste and excess fluids from the blood.
Location and Structure
- The kidneys are normally located in the human body in the upper abdominal cavity.
- The functional unit of the kidney is called a nephron.
- The kidneys receive blood from the renal arteries.
Glomerulus Function
- The glomerulus is a cluster of capillaries in the nephron responsible for filtration.
- The primary purpose of the glomerulus is to filter the blood and remove waste products.
- Filtration in the glomerulus depends on factors such as blood pressure, permeability of the glomerular capillaries, and the concentration of proteins in the blood.
Kidney Functions and Tests
- A rise in the level of serum urea generally indicates kidney dysfunction or failure.
- The blood urea nitrogen (BUN) test measures the end product of protein catabolism.
- A qualitative examination of urine provides clues to kidney function and potential diseases.
Kidney Function and Diet
- A high-protein diet may increase the blood urea level.
- The normal range for serum urea level varies, but a rise in serum urea level indicates impaired glomerular function.
Non-Kidney Functions
- The kidney is not responsible for storing bile.
