REVIEW SHEET EXERCISE 9 Renal System Physiology NAME: LAB TIME/DATE: Simulating Glomerular Filtration The following questions refer to Activity 1: Investigating the Effect of Flow Tube Radius on Glomerular Filtration. 1. Describe the effect of increasing the afferent radius on glomerular filtration rate and glomerular pressure. As the afferent radius increases the glomerular filtration rate and glomerular pressure both increase the pressure in slow steps the filtration rate greatly

withdrawal of urine. Straight catheters are used for intermittent withdrawals; indwelling (Foley) catheters are inserted and retained in the bladder for continuous drainage of urine into a closed system. Purpose Intermittent catheterization is used for the following reasons:• To obtain a sterile urine specimen for diagnostic evaluation; to empty bladder content when the patient is unable to void (urinate) due to urinary retention‚ bladder distention‚ and obstruction‚ or to measure residual urine after

` Project 3.4.3: The Blood/Urine Connection Introduction Water is obtained from food‚ drink‚ and from reactions that occur in the body. The kidneys process and balance the amount of water that enters your system with the amount that is released. The digestive system helps rid the body of solid wastes‚ but some of the wastes in the blood are the remnants of the digestion of food products. For example‚ when amino acids are broken down by the body‚ ammonia (NH3) is formed. This product is so

infection. Left untreated or unresolved‚ it can progress to a chronic condition that lasts for months or years‚ leading to scarring and possible loss of kidney function. The most common cause of pyelonephritis is the backward flow (reflux) of infected urine from the bladder to the upper urinary tract. A blockage or abnormality of the urinary system‚ such as those caused by stones‚ tumors‚ congenital deformities‚ or loss of bladder function from nerve disease‚ increases a person’s risk of pyelonephritis

Micro-extraction of urine and/or stomach contents and analysis by TLC Abstract Thin Layer Chromatography (TLC) is one of the oldest chromatographic techniques used for the identification of compounds and for determination of the presence of trace impurities. The aim of the experiment was to determine two unknown samples (X and Y) by comparing results to the known standard drugs‚ of which there was five‚ using a specific TLC method. The same technique was used for the determination of

Urine Testing Science Research What is urinalysis? It is the physical‚ chemical‚ and microscopic examination of urine. Urine testing is an important tool used for medical testing on patients. It can be useful for providing information on a person’s body. Its checks many things like‚ for diseases‚ sugar‚ pH (acidity)‚ protein‚ and bacteria. Doctors or adults at home use urine dipsticks. They are narrow plastic strips which have several squares of different colors attached to it. Each square

if there is a relationship between fluid intake and urine output‚ by measuring my daily fluid intakes and urine outputs. Hypothesis: The volume of urine I will produce will be at least half of the volume of fluids I will drink‚ due to the body’s ability to carry out a water balance just as one would have on oxygen‚ carbon dioxide to maintain a healthy and working body. For example if I drink 1000cm3 of fluids then the expected amount of urine I should produce would be around 4000 cm3 to 6000 cm3
