An artificial kidney is a device that removes water and wastes from the blood. In one such device, i.e., the hollow fiber hemodialyzer, bloodflows from an artery through the insides of a bundle of cellulose acetate fibers. Dialyzing fluid, which consists of water and various dissolvedsalts, flows on the outside of the fibers. Water and wastes-principally urea, creatinine, uric acid, and phosphate ions-pass through the fiberwalls into the dialyzing fluid, and the purified blood is returned to a vein. At some time during the dialysis of a patient in kidney failure, thearterial and venous blood conditions are as follows:Flow rate (mL min-1)Urea concentration (mg mL-1)Arterial Blood-In2001.90Venous Blood-Out1951.75Calculate the rate at which water is being removed from the blood. Your answer should have units of mL/min.

Calculation:Net Flow Rate: 200 mL/min - 195 mL/min = 5 mL/minTherefore, the rate at which water is…

A medical technician is trying to determine what percentage of a patient's artery is blocked by plaque. To do this, she measures the blood pressure just before the region of blockage and finds that it is P₁, while in the region of blockage it is P2. Furthermore, she knows that blood flowing through the normal artery just before the point of blockage is traveling at v₁, and the density of this patient's blood is p. The patient is laying down so there are no differential effects due to gravity. a. Symbolically, what is the ratio of the artery radius at the blockage, r2, to the ratio of the artery radius at the blockage, r₁? (find r₂/r₁) b. Find the numerical value of r2/r1. P₁ = 1.20x104 Pa, P₂=1.15×104 Pa, v₁ =30.0 cm/s, p = 1060 kg/m³.
The following is a practice question for an upcoming test: At a resting pulse rate of 77 beats per minute, the human heart typically pumps about 73 mL of blood per beat. Blood has a density of 1060 kg/m3. Circulating all of the blood in the body through the heart takes about 1 min for a person at rest. On average, what mass of blood does the heart pump with each heart beat in kg? mass per heart beat:

In the video, the water level was 15 milliliters before adding the chain, and 20 milliliters after adding the chain. When I weighed the chain, its mass was 70.6 grams. I believe the chain is solid metal (not gold plated), but is probably a blend of gold and other metals. I looked up that gold has a density of 19.3 g/ml, while the other metals like silver and copper usually blended with gold have a combined density of about 9.7 g/ml. Determine what percentage of the chain is gold, by mass, to at least 1 decimal place? % ४९
During inspiration, the volume of the lungs is actively increased by the action of the diaphragm. As the volume of the lungs increases, the pressure within the lungs falls about 1 mmHg below atmospheric pressure. Air rushes into the lungs due to this pressure difference.
