How do molecular solutes differ from ionic solutes when dissolved in solution?
Molecular solutes will not conduct electricity when dissolved in solution, and ionic solutes will conduct electricity when dissolved in solution.
What kinds of substanances dissolve in water?
solutes, solvents are the substances that do the dissolving solutes, solvents are the substances that do the dissolving
How does principle of like dissolves like explain the differing solubilities of solutes in various solvent?
Generally polar solutes are dissolved in polar solvents and nonpolar solutes are dissolved in nonpolar solvents.
What is the relationship among solutions solutes ans solvents?
A solution is a homogeneous mixture in which one or more solutes are dissolved in a solvent.
Which substance in the air is the solvent and which substances are the solutes?
Moisture in the air works as solvent and soluble substances present in the air are solutes.
The chief force pushing water and solutes out of the blood across the filtration membrane is?
glomerular hydrostatic pressure (glomerular blood pressure)
All the solutes are filtered out except proteins (large molecules) during?
Glomerular filtration
What does glomerular filtration rate regulation mechanisms primarily affect?
HPg - Much like other capillaries in the body, hydrostatic pressure within the glomerular capillaries produces net outward movement of fluid. Unique to glomerular capillaries, HPg is consistently higher than other capillaries (~55 mm Hg), which ensures the one-way movement of fluid and solutes out of the glomerulus under normal conditions.
Which region of the renal tubule reabsorbs the largest amount of water and solutes from the filtrate?
glomeruli
What is the overall process that refines the filtrate and ultimately returns water and valuable solutes to the blood is known as?
reabsorption
What is the force that causes water and solutes to be filtered by the glomerulus?
Hydrostatic pressure. The vessel draining the glomerulus has a smaller internal diameter than the vessel feeding it. This means that blood doesn't exit the glomerulus as quickly as it enters. This creates a pressure, called hydrostatic pressure, within the glomerular capillaries and that pressure forces the fluids and many solutes into the glomerular capsule surrounding the glomerulus.
What is the osmolarity of the filtrate at the end of the proximal tubule?
Isotonic- 300 mOsm Per Pearson Yes, the osmolarity of the filtrate would be about 300 mOsm because both solutes and water are reabsorbed in the proximal tubule. As particles are reabsorbed, water follows osmotically.
Define glomerular filtration rate Name and describe the pressures which are effective at the glomerulus under normal conditions and result in glomerular filtration?
Glomerular filtration is a passive process in which hydrostatic pressure forces fluids and solutes through a membraneThe glomerular filtration rate (GFR) is directly proportional to the net filtration pressure and is about 125 ml/min (180 L/day).The glomeruli function as filters. High glomerular blood pressure (55 mm Hg) occurs because the glomeruli are fed and drained by arterioles, and the afferent arterioles are larger in diameter than the efferent arterioles.
How do you define term membrane transport?
Membrane transport is the collection of mechanisms that regulate the passage of solutes and small molecules through biological membranes.
Would the passive movement of substances occur if the interstitial solute concentration was the same as the filtrate solute concentration?
No. Solutes move down their concentration gradient, from areas of high concentration to areas of lower concentration.
The thick segments in the ascending limb of the loop of Henle contain A ADH-regulated permeability. B an aldosterone-regulated pump. C transport mechanisms that pump solutes out of the filtra?
a
What would happen to net solute movement if the solute concentration of the filtrate were 350 milliosmol and that in the interstitial spaces of the kidney were 350 milliosmol?
Solutes would move toward the the interstitial space because 350 mOs is very low for the interstitial space. It is normally 1200 at the medullary-pelvis junction so solutes will move in that direction in an effort to normaleize it.
