Renal Physiology: Filtration Rate and Flow

Constricting the afferent arteriole reduces blood flow into the glomerulus, leading to a decrease in both glomerular filtration rate and renal plasma flow.

Angiotensin 2 constricts the efferent arteriole, increasing pressure inside the glomerulus. This raises glomerular filtration rate while renal plasma flow might remain the same, leading to a higher filtration fraction.

Increased plasma protein concentration makes the blood thicker, hindering the filtration process. This results in a lower glomerular filtration rate and a lower filtration fraction.

Constricting the ureter, the tube that transports urine, can reduce pressure within the kidney, leading to a decrease in glomerular filtration rate and filtration fraction.

Dehydration increases blood viscosity, reduces blood flow to the kidneys, and leads to an increase in the concentration of solutes in the blood. This combination results in a lower GFR, a lower RPF, and a higher filtration fraction.

Constricting the afferent arteriole decreases blood flow into the glomerulus, leading to reduced glomerular filtration rate (GFR) and renal plasma flow (RPF).

Angiotensin 2 constricts the efferent arteriole, increasing pressure within the glomerulus, raising GFR. While RPF remains the same, the increased pressure leads to a higher filtration fraction.

Increased protein concentration makes the blood thicker, hindering filtration, resulting in a lower GFR and a lower filtration fraction.

Constriction of the ureter, the tube carrying urine, reduces pressure within the kidney, leading to a decrease in GFR and filtration fraction.

Dehydration increases blood viscosity, reduces blood flow to the kidneys, leading to a lower GFR and RPF, but increased filtration fraction.

Constricting the afferent arteriole reduces blood flow into the glomerulus, leading to a decrease in both glomerular filtration rate (GFR) and renal plasma flow (RPF).

Angiotensin II constricting the efferent arteriole increases pressure within the glomerulus. This leads to a higher GFR while RPF remains the same, resulting in a higher filtration fraction.

Increased plasma protein concentration makes blood thicker, hindering filtration, resulting in a lower GFR and filtration fraction.

Constricting the ureter reduces pressure within the kidney, leading to a decrease in GFR and filtration fraction.

Dehydration increases blood viscosity, reduces blood flow to the kidneys, leading to a lower GFR and RPF, but an increased filtration fraction.

Constricting the afferent arteriole reduces blood flow into the glomerulus, causing a decrease in both glomerular filtration rate (GFR) and renal plasma flow (RPF).

Angiotensin 2 constricts the efferent arteriole, increasing pressure inside the glomerulus. This raises GFR, while RPF might remain the same, leading to a higher filtration fraction.

Increased plasma protein concentration thickens the blood, making it harder for fluid to move through the glomerulus, decreasing GFR and the filtration fraction.

Constricting the ureter, which carries urine, reduces pressure within the kidney, leading to a decrease in glomerular filtration rate (GFR) and filtration fraction.

Dehydration increases blood viscosity (thickness), reduces blood flow to the kidneys, and raises solute concentration in blood. This leads to a lower GFR, a lower RPF, but a higher filtration fraction.

Constricting the afferent arteriole reduces blood flow into the glomerulus, lowering both glomerular filtration rate (GFR) and renal plasma flow (RPF).

Constricting the efferent arteriole increases pressure inside the glomerulus, raising GFR. Although RPF might stay the same, the increased pressure leads to a higher filtration fraction.

Increased protein in the blood makes it thicker, slowing down filtration. This results in a lower GFR and a lower filtration fraction.

Constricting the ureter, the tube carrying urine, reduces pressure within the kidney, decreasing GFR and filtration fraction.

Dehydration makes the blood thicker, reduces blood flow to the kidneys, and increases the concentration of solutes in the blood. This leads to a lower GFR, a lower RPF, but a higher filtration fraction.
