Why is proper blood pressure necessary for proper kidney function?
A little more than 20% of the total blood pumped by the heart enters the kidneys. One of the main functions of the kidneys is to remove waste products from the blood. Maintenance of high rate of blood flow and normal blood pressure in the kidneys is needed for the formation of urine.
What contains more water the blood going into the kidneys or the blood leaving it?
Blood entering the kidneys has more water; the water is extracted by the kidneys and sent through the ureter to the bladder.
Why does blood flow slowly in a kidney during a vigorous exercise?
Blood flow to the kidneys and abdomen decreases duringexercise because the muscles need more oxygen, and so, the blood vessels in them dilate. This causes more blood to go to the muscles, leaving less blood in the rest of the body.
What happend when blood flow to the kidneys decreases?
I think if blood flow to the kidneys decreased, then the filtration rate of the blood would also decrease. The blood is forced through the anterior arteriole at high hydrostatic pressure- forcing the plasma through the basement membrane of the glomerulus in our kindneys' nephra- the bits that do the filtering.
Which organ holds more blood Liver or kidneys?
Liver
Why does a person urinate more when they are lying down with their legs raised 30 cm?
A person urinates more when lying down with their legs raised because there is a lot of pressure in the urinal bladder. This makes a person urinate longer with a stronger jet because less reserves are left in the bladder.
What cleans the blood?
Its simple the heart filters the blood.The heart does not filter blood. Your kidneys and liver filter toxins from your blood. Mostly your kidneys. Your liver aids more in digestion, but also filters blood.
Why is urine output decreased during hypovolemic shock?
If the kidneys are getting enough blood to function well they concentrate the urine in an effort to correct the low blood volume. In more severe cases they cannot make much urine because they are not getting enough blood flow.
How is diuresis associated with caffeine?
Caffeine causes your heart to pump slightly harder and faster. The kidneys then sense the increase in blood flow and misinterpret this as that you have more fluid on board than you need. They then filter fluid out of the blood stream and create urine.
What are function of the renal artery?
The renal artery supplies blood to the renal system, or the kidneys. The renal artery differ with the renal vein in containing the less concentration of co2 and more concentration of urea
How much unfiltered blood enters the kidney per minute?
In an otherwise healthy person with no cardiac problems, 100-120 cc's/mLs of unfiltered blood enter each kidney and are filtered at the glomerulus per minute. 99% of this is reabsorbed in the tubules, and thus only about .5cc is sent to the bladder per minute. Thus it is true that the average person forms 30cc urine per hour.
What is the relationship of kidneys and blood Oxygen?
The kidneys monitor oxygen levels in blood and if they are low then the kidneys release erythropoetin in to the blood stream. Red bone marrow cells have erythropoetin receptors and start to produce erythrocyte's in the bone marrow, then they go into the blood stream. This goes on until leaves are back to normal. Since there are more blood cell there is more oxygen carrying capacity.
