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

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

Pyelonephritis is an inflammation of the kidney and upper urinary tract that usually results from noncontagious bacterial infection of the bladder‚ known as cystitis. Acute pyelonephritis is most common in adult females but can affect people of either sex and any age. Its onset is usually sudden‚ with symptoms that are often mistaken as the result of straining the lower back. Pyelonephritis often is complicated by systemic infection. Left untreated or unresolved‚ it can progress to a chronic

RELEVANCE & FIELD APPLICATION The kidney is an amazing organ. It makes urine and helps to control your blood pressure. It also keeps your bones strong and healthy‚ and controls manufacture of red blood cells. However‚ this organ is challenged with many diseases and complications. Thus‚ my Research Project is based on one of the most common problem: S KIDNEY STONE FORMATION A RESULT OF PATIENTS’ LIFE STYLE There has been an increase in the number of kidney stone cases at Diagnostic & Specialist

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

Primary functions of the kidney: — Maintaining homeostasis through the regulation of fluid and electrolytes and removing wastes through the formation of urine. ž Other important functions: — Regulation of acid-base balance — Control of blood pressure — Renal clearance — Regulation of RBC production — Synthesizing vitamin D to the active form — Secreting prostaglandins — Regulating calcium and phosphorus balance. Nephron ž Each kidney has about 1 million

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

urea. The kidneys remove unwanted substances such as urea‚ excess water and salt. © Boardworks Ltd 2009 What is urea? Excess amino acids in the body are broken down by the liver‚ producing a waste substance called urea. This process is important because it converts toxic ammonia to urea‚ which is done using carbon dioxide. Once formed‚ urea is transported by the circulatory system to the kidneys. The kidneys filter the blood‚ removing urea and excess water and salt‚ which forms urine. Urine is stored
