Chloride in Urine in Different Circumstances Aim: To determine the chloride content by titrating mixtures of urine against potassium thiocyanate under in different circumstances. Research Question: How do different conditions of urine samples collected affect its concentration of chloride which is measured by titrating the mixture of urine with potassium thiocyanate until it turns red? Hypothesis: The greater the consumption of food‚ the higher the chloride concentration in urine. This can

Urine production If body fluids are hypo osmolar‚ then kidney will produces hypo osmolar urine. (Dilute urine) If body fluids are hyper osmolar (dehydration) then kidney produces hyperosmolar urine. (concentrated urine) In the renal cortex the osmolarity of interstitial fluid is 300mOs/L going to 1200mOs/L in the papilla. From the cortex to the papilla there is an increasing hyper osmolarity of the interstitial fluid. Cortico papillary osmolarity gradient. Urine with osmolarity more than 300mOs/l

Urine Specific Gravity Each day an adult excretes between 800ml and 2000mL of urine. This amount varies depending on various conditions that can influence fluid loss and fluid intake. For example‚ the loss of fluid through heavy sweating in hot weather reduces urine amounts. The minimum volume of urine needed to remove body wastes from an adult is about 500mL/day. The specific gravity of urine can be an indicator of disease or disruption in normal metabolism. As you recall from our earlier discussions

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

URINE WHAT IS URINE is a liquid by-product of the body secreted by the kidneys through a process called urination(or micturition) and excreted through the urethra. Kidney’s waste from protein metabolism urination - the primary method for excreting water-soluble chemicals from the body. Dark yellow urine is often indicative of dehydration. Yellowing/light orange may be caused by removal of excess B vitamins from the bloodstream. Certain medications such as rifampin and phenazopyridine can

Kharishma Patel BIO 3422-E Urine Analysis Lab Objective The objective of this experiment shall be to examine the effects of different types of fluids on the renal system including rate of urine production‚ pH‚ and specific gravity. Hypothesis The group drinking water will have the highest rate of urine production. The group that drinks water only when thirsty will have the lowest rate of urine production. The specific gravity of urine for all treatment groups will be around 1.000. The pH for

following Tuesday class of MSTC‚ who showed him one way to think about these problems. This technique is called the Analytic Hierarchy Process. The first step in AHP is to ignore the jobs and just decide the relative importance of the objectives. Peter does this by comparing each pair of objectives and ranking them on the following scale: Comparing objective i and objective j (where i is assumed to be at least as important as j)‚ give a value aij as follows: Value aij 1 3 5 7 9 Comparison

The walls of duct in the kidney respond to ADH and the cells in the walls have membrane-bound receptors for ADH‚ to which the ADH binds to these receptors and causes a chain of enzyme-controlled reactions in the cell. The completion of these reactions is inserting vesicles containing water-permeable channels (aquaporin’s) into the cell surface membrane‚ thus making walls more permeable to water. When ADH is increased in the blood flow‚ more water-permeable channels are inserted
