You correctly answered: afferent arteriole, glomerular capillary, efferent arteriole.
What will happen to the glomerular capillary pressure?
When glomerular capillary pressure or the diameter of glomerular capillaries increases, the tension in the capillary walls will rise, and constriction of the efferent arteriole constriction will also augment the increase in wall tension.
What happened to the glomerular capillary pressure and filtration rate when you decreased the radius of the efferent arteriole?
Describe the effect of decreasing the afferent arteriole radius on glomerular capillary pressure and filtration rate. By decreasing the afferent arteriole radius, this increases the glomerular filtration rate and pressure increases.
What was the effect on GFR when the efferent radius was reduced?
You correctly answered: A decreased efferent arteriole radius will increase the rate of glomerular filtration.

What can help increase GFR?
Avoid processed foods and choose fresh fruits and vegetables instead. Follow a low-salt diet. Salt should be limited especially if you have high blood pressure, protein in your urine, or swelling, or difficulty breathing. Eating less than 2000 mg a day of sodium is recommended.
How can I raise my GFR fast?
How to Increase eGFR
- Make sure your blood pressure is in the healthy range (around 120/80) [17, 18]
- Aim for a healthy weight [18, 24]
- Eat a lot of fruits and vegetables [25]
- Quit or reduce smoking [18, 22, 26]
- Exercise for at least 30 minutes several times per week [27, 28, 29, 30]
What happens to GFR when the efferent arteriole is constricted?
During efferent arteriole constriction, GFR is increased, but RPF is decreased, resulting in increased filtration fraction. During a state of increased plasma protein concentration such as during multiple myeloma, GFR is decreased with no change in RPF, resulting in decreased FF.
How does efferent arteriole constriction increased GFR?
Constriction of the efferent arteriole alone also reduces RBF but with an increase in glomerular capillary pressure. This favors a relative increase in the GFR over the RBF, so that the filtration fraction is increased.
How does changing the afferent and efferent arteriole affect GFR?
Vasodilation in the afferent arteriole and vasconstriction in the efferent arteriole will increase blood flow (and hydrostatic pressure) in the glomerulus and will increase GFR. Conversely, vasoconstriction in the afferent arteriole and vasodilation in the efferent arteriole will decrease GFR.
What happens to the glomerular filtration rate and glomerular pressure as the afferent radius is increased?
Describe the effect of increasing the afferent radius on gomerular filtration rate and glomerular pressure. Both glomerular filtration rate and glomerular pressure will INCREASE.
What is normal GFR for age?
GFR Number by Age
The normal range of Kidney Glomerular Filtration Rate is 100 to 130 mL/min/1.73m2 in men and 90 to 120mL/min/1.73m2 in women below 40. GFR decreases progressively after the age of 40 years.
What can affect GFR results?
Your test results may be affected if you:
- Have changing kidney function.
- Are severely malnourished, are underweight, or have muscle-wasting disease.
- Are severely overweight.
- Are a bodybuilder.
- Have a neuromuscular disorder.
- Are taking certain medicines, including chemotherapies and kidney medicines.
- Eat a lot of meat.
What is the normal range for glomerular filtration rate?
According to the National Kidney Foundation, normal results range from 90 to 120 mL/min/1.73 m2. Older people will have lower than normal GFR levels, because GFR decreases with age.
What are the first signs of kidney problems?
Symptoms
- Nausea.
- Vomiting.
- Loss of appetite.
- Fatigue and weakness.
- Sleep problems.
- Urinating more or less.
- Decreased mental sharpness.
- Muscle cramps.
What is a normal GFR for a 70 year old woman?
However, we know that GFR physiologically decreases with age, and in adults older than 70 years, values below 60 mL/min/1.73 m2 could be considered normal.
What is a good number for your kidneys?
If you have a GFR number of 60 or more together with a normal urine albumin test, you are in the normal range. But you’ll still want to talk to your doctor about when you should be checked again. If you have a GFR number less than 60, it may mean you have kidney disease.
What color is your urine when your kidneys are failing?
When kidneys are failing, the increased concentration and accumulation of substances in urine lead to a darker color which may be brown, red or purple. The color change is due to abnormal protein or sugar, high levels of red and white blood cells, and high numbers of tube-shaped particles called cellular casts.
Can kidneys repair themselves?
It was thought that kidney cells didn’t reproduce much once the organ was fully formed, but new research shows that the kidneys are regenerating and repairing themselves throughout life. Contrary to long-held beliefs, a new study shows that kidneys have the capacity to regenerate themselves.
