What else can I help you with?
An obstruction in the glomerulus would affect the flow of blood into what?
efferent arteriole
An obstruction in the afferent arteriole would reduce the flow of blood into the?
glomerulus, leading to a decrease in blood pressure within the glomerulus. This reduction in pressure may impair the filtration process in the kidney, potentially leading to decreased urine production and retention of waste products in the body.
Would protein concentration increase if glomerulus becomes constricted?
No, protein concentration in the blood would not increase if the glomerulus becomes constricted. The glomerulus is responsible for filtering the blood to form urine, and a constriction would reduce the filtration rate. This might lead to decreased urine output and retention of substances normally excreted in urine, but it would not directly affect the protein concentration in the blood.
Where would you find the glomerulus?
The glomerulus is found in the kidneys. It is a cluster of tiny blood vessels where blood is filtered to form urine.
An obstruction in the inferior vena cava would hamper the return of blood from where?
Abdomen and pelvis
How would pressure in the glomerulus be affected by constricting the afferent arteriole?
Constricting the afferent arteriole would decrease blood flow into the glomerulus, leading to a decrease in pressure within the glomerulus. This may result in a decrease in glomerular filtration rate and a reduction in the formation of urine.
What would you find inside the glomerulus?
Inside the glomerulus, you would find a network of capillaries where blood is filtered to form urine. Podocytes, specialized cells that wrap around the capillaries, help regulate the filtration process by preventing large molecules like proteins from passing through.
How would increasing the amount of water in blood affect the blood pressure?
Blood pressure would increase
How would increasing the amount of water in the blood affect the blood pressure?
Blood pressure would increase
How would decreasing the amount of water in blood affect the blood pressure?
Blood pressure would decrease
Would Decreasing the amount of water in the blood affect blood pressure?
Blood pressure would decrease
In the absence of any regulatory mechanisms what effect do you think an increase in blood pressure would have on glomerular filtration rate?
Generally speaking, it would increase. However, it depends on the reason for the hypertension. For instance, if there is an obstruction or constriction of the renal artery (stenosis, malignancy, etc...) the physiologic affect would to increase the body's BP. This is due to the fact that the obstruction is decreasing hydrostatic pressure to the glomerulus, and transiently decreasing GFR. The body compensates by increasing BP to increase GFR. Patients that present with a renal artery stenosis could in fact be hypertensive with a decreased GFR.
