Kidney Physiology and Blood Plasma Osmotic Pressure

Front

The daily volume of primary urine of an adult:

Back

160-180 L

Front

Difference in the composition of extracellular fluid from intracellular fluid: more sodium and phosphates, more potassium and Cl anions, more potassium and HCO3 anions, more sodium and Cl anions, more calcium and phosphates

Back

more sodium and Cl anions

Front

The main cation that determines the osmotic pressure of the extracellular fluid is:

Back

Na+

Front

Osmotic pressure of blood plasma is created mainly by: calcium ion, potassium ion, sodium ions, chlorine ion, phosphate ions

Back

sodium ions

Front

The structural and functional unit of the kidney is:

Back

nephron

Front

The distal convoluted channel of the nephron flows into:

Back

collecting tube

Front

The share of cortical nephrons in the kidney accounts for: less than 5%, 10-15%, 30-35%, about 40%, 60-70%

Back

60-70%

Front

The component of the renal cell filter with the smallest pore diameter is: mesangial cells, juxtaglomerular cells, podocytes, endothelial cells of vascular capillaries of the glomerulus, basal membranes of the endothelium glomerulus and epithelium of the capsule

Back

basal membranes of the endothelium glomerulus and epithelium of the capsule

Front

The part of the osmotic pressure of blood plasma created by plasma proteins is designated as:

Back

oncotic

Front

The magnitude of the oncotic (colloid osmotic) pressure of blood plasma in norm:

Back

25-35 mm Hg.
