Question
Chapter 24.4, Problem 5QC
Summary Introduction
To review:
The three pressures that combine for determining the net filtration pressure. The pressure(s) that promote(s) filtration and the pressure(s) that oppose(s) filtration.
Introduction:
Filtration occurs only when there is a pressure gradient which pushes water as well as solutes via the filtration membrane. Two forces namely, COP (colloid osmotic pressure) and hydrostatic pressure act together in a capillary bed for determining the NFP (net filtration pressure) of the bed.

- What is the difference between filtration and reabsorption?arrow_forward1) What substances are reabsorbed from the tubules by active reabsorption and what substances by diffusion? 2) What substances are actively secreted by the tubules, and in what parts of the tubules are these substances secreted?arrow_forwardGlomerular filtration is affected by forces that oppose and promote filtration. What are these forces and explain the theory behind net filtration pressure?arrow_forward
- Drugs that increase urine flow (diuretic drugs) are often employed in the treatment of hypertension (high blood pressure) or other disease states. Three physiological categories of such drugs are ones that (i) function as loop diuretics, (ii) inhibit the action of aldosterone, and (iii) block Na+ channels in the collecting ducts. Explain why each of these categories would be expected to increase Na+ excretion and urine flow.arrow_forwardList and describe the three filtration barriers that substances leaving the plasma must pass through before entering the tubule lumen.arrow_forwardHow is the permeability of the distal convoluted tubule and the collecting tubule controlled for regulating the water content inside the body?arrow_forward
- If urine/filtrate is hyperosmotic to the interstitial fluid, fluid would go from the interstitial fluid to the urine/filtrate. How does this conserve water? Wouldn’t this NOT conserve water but rather increase the amount of water that is excreted via urine?arrow_forwardDiuretics cause sodium excretion. Sodium follows water. Therefore, diuretics lead to a reduction in volume (remember BP = heart rate x volume x blood vessel tone (SVR)). Since diuretics lower volume, they lower BP. When would diuretics be indicated? When would they be contraindicated?arrow_forwardAntidiuretic hormone (ADH) is produced in the pituitary gland and regulates the body's fluid volume and osmolality by affecting the number of active aquaporins (water channels) in the proximal tubules and the collecting duct. But what is it, above all, that drives the filtrate out of the tubules? a) Osmotic pressure formed depending on the composition of the filtrate b) Osmotic gradient in the medullary (kidney marrow) c) Hydrostatic pressure from the filtrate in tubules d) Blood pressure in the capillaryarrow_forward

Choose from the following: (A) hydrogen ions diffuse out of the glomerular filtrate of the proximal convoluted tubule, through extracellular fluid and into the peritubular blood (B) carbon dioxide diffuses into the proximal convoluted tubule cell from peritubular capillary blood; undergoes a chemical reaction to form carbonic acid; dissociates into hydrogen and bicarbonate ions; the hydrogen ion diffuses into the glomerular filtrate of the proximal convoluted tubule (C) hydrogen ions diffuse out of the peritubular capillary blood, through extracellular fluid and into the filtrate of the proximal convoluted tubule (D) carbon dioxide diffuses into the proximal convoluted tubule cell from the glomerular filtrate; undergoes a chemical reacdtion to form carbonic acid; dissociates into hydrogen and bicarbonate ions; the hydrogen ions diffuse into the peritubular bloodarrow_forwardPressure in the renal artery is 100 mm Hg and the pressure in the renal vein is 50 mm Hg. The resistance of the afferent arteriole equals 0.5 mm Hg•min/L and the resistance of the efferent arteriole equals 0.5 mm Hg•min/L. What is the pressure in the glomerulus?arrow_forwardWhich of the following results in filtration? 1) hydrostatic pressure in the peritubular capillaries 2) hydrostatic pressure in the glomerulus 3) colloid osmotic pressure in the glomerulus 4) colloid osmotic pressure in the peritubular capillariesarrow_forward
