Approximately 25%
Therefore, over a very short time span the entire blood volume of the body passes through the kidneys for control of its chemical composition.Each minute, the remaining 75 to 80 percent of the cardiac output is pumped from the heart to the other tissues of the body.  The average weightof an adult human kidney is approximately one-quarter pound. Each kidneyis approximately 4 inches long, 2.5 inches wide, and 1.5 inches thick.The kidney receives about 20 percent of the blood coming from theheart each time it beats. The rate of blood flow through both kidneys isapproximately 1.2 liters per minute.The basic functioning unit of the kidney is called the nephron Main navigation | Main content. Go to the U of M home page. Cardiac output in a normal individual at rest ranges between 4 to 6 liters per minute, but during severe exercise the heart may be required to pump three to four times this amount.  Assume total blood volume is 8% of weight, that her heart pumps her total blood volume once a minute, and that her renal blood flow is 25% of her cardiac output.  How much blood flows through the kidneys in one minute?   Normal renal blood flow is about 1litre/min, around 20% of cardiac output.   The kidney has among the highest blood flow by weight of any tissue, high blood flow is n … eeded to efficiently excrete waste products in the bloodstream. In the typical human-the kidneys receive about 20% of the total output from the heart. The kidneys receive about 20 percent of the heart's blood output and play a vital role in keeping the dog in normal metabolic balance. When one or both kidneys are malfunctioning, it can lead to kidney failure.  A large amount of circulating blood flows through the kidneys. Approximately 25% of the cardiac output or 1200 ml of blood per minute is received by the kidneys. One liter of urine is the end product of more than 1000 liters of circulating blood processed through the kidneys.  Cardiac output is the volume of blood that your heart pumps per minute. With it being increased, it means that there is an increase in volume of blood that your heart pum … ps around the body.  Hope this helps with whatever you're doing-like PE BTEC... Answer   Cardiac output is the volume of blood the heart pumps within one minute. Cardiac output (CO) is equal to the stroke volume (SV) of the heart multiplied by … the heart rate (HR). Thus, cardiac output is given by the equation: CO=HR X SV. 27 people found this useful. Along with stroke volume (SV), cardiac output is a global blood flow parameter of interest in haemodynamics – hæmodynamics the study of the flow of blood under external. Forces the factors affecting stroke volume and heart rate also affect cardiac. output Because cardiac output is related to the quantity of blood delivered to various parts of the body, it is an important indicator of how efficiently the heart can meet the demands of the body. The brain utilizes fully 25 percent of the body's total oxygen consumption. The arteriovenous O2 difference is relatively high since the brain receives only 15 percent of the cardiac output. The arteriovenous difference is 6.6 mL per 100 ml., falling from 19.6 to 13 mL per 100 mL as blood passes through the brain (Fig. 17-2). The average cerebral blood flow in humans is approximately 55 mL per 100 g of brain tissue per minute. This is a little over 700 mL/min for a 1350-g brain.
