Study Notes
Kidney Functions
- Regulate blood pressure through renin release
- Maintain electrolyte balance in the body
- Remove waste and excess substances from the bloodstream
Main Structural Unit
- Nephron is the primary functional unit of the kidney responsible for urine formation
Urine Formation Process
- Filtration, reabsorption, and secretion all contribute to urine formation
Glomerular Filtration Rate (GFR) Determinants
- Blood pressure in glomeruli
- Different factors including blood volume and osmotic pressure
- Affected by afferent and efferent arteriolar resistance
Main Mechanism of Reabsorption
- Active transport plays a crucial role in reabsorbing water, ions, and nutrients back into the bloodstream
Non-Kidney Function
- Hormonal regulation of metabolism is NOT primarily a kidney function
Glomerular Filtration Intensity
- Primarily determined by systemic blood pressure and pressure gradient in the glomerular capillaries
Factors Influencing Filtration Rate
- Plasma protein levels, blood pressure, and the permeability of the glomerular membrane
Ultrafiltrate Composition
- Consists mainly of water, electrolytes, urea, glucose, and amino acids; lacks blood cells and large proteins
Principle of Dialysis
- Utilizes diffusion to remove waste products from the blood, mimicking kidney function in filtering toxins and excess substances
