How much blood plasma do the kidney's filter in 24 hours?
There are alot of factors that determine how much plasma gets filtered, it depends on the gender, weight, cardic outputm, hematocrit value, hormone levels and blood pressure of the person. But lets consider a perfectly health individual with a cardic output of 5L/min and a hematocrit of 0.40, he would have a renal bloodflow of 1L/min and a renal plasma flow of 600 ml/min. Renal plasma flow = 0.6 l/min * 60 * 24 = 864 L / 24 hour The filtation rate is quite a bit lower though, the filtration faction is 20% and thus the answer is 864 L x .20 = 172,8 L / 24 hours. Hope this helps
If liver filters blood and kidneys filter blood why do I need both?
They filter blood in different ways, but in many cases work together. The liver picks out chemicals and such that need to be chemically changed for many different reasons. For instance, it can pull fat molecules out of blood for packaging and transport to fat stores, or it can pull toxins out and turn them into non-toxic forms. Basically, the liver does most of the biochemistry in your body, and since it uses the blood stream as a means of transporting things with the rest of the body, must filter it in order to grab all of the things it needs to work with. The kidneys filter blood in a drastically different way. They let small stuff fall out of the blood randomly into them. Then, they decide whether the randomly fallen-out molecule is useful or not. If it is, they pull it back into the blood. If it isn't, they let it continue down the path toward urine for removal from the body. For instance, the less-toxic molecule that used to be a toxin would be dropped into the kidneys and let to fall into the urine collection for excretion, while sugar molecules would be picked out and shoved back into the blood so that they could feed cells. Overall, the liver filters blood so that it can biochemically meddle with it, while the kidneys filter the blood so that they can get rid of all of the unwanted crap that happens to be in it.
How much water can the average kidney filter in an hour?
The rate of filtration is approximately 125 ml/min or 45 gallons (180 liters) each day. 7.5 liters of blood per hour. how much water the kidneys can filter out of the blood in an hour depends on volume of extra water in circulation. A common formula is more than 0.5mL/kg/hour. for example, if you are 80kg, urine output per hour would be 40mL/hour.
