Diabetes Mellitus Lab Report
Analysis: Which sample do you suspect has diabetes mellitus? Provide your reasons.
Diabetes mellitus is a condition created by the inadequate secretion of insulin from the pancreas. Insulin is a hormone that allows your body to use carbohydrates or store them for future use. Inadequate amounts of insulin causes a condition called hyperglycemia, which is an excessive amount of glucose in the blood stream. When the blood is filtered through the kidney, a large of amount of glucose is retained in the filtrate and a large amount of it cannot be reabsorbed and is excreted out as urine. The large amount of glucose within the filtrate changes the osmotic pressure within the nephron, which reduces the amount of water that is reabsorbed back into the bloodstream. The sample with diabetes mellitus should hypothetically result in the sample of urine turning orange after 10 drops of Benedict’s Solution was added and the sample was heated. The sample turning orange after the Benedict’s Test was done on the sample would mean that the sample tested positive for

Antidiuretic hormones regulate water reabsorption by making the upper part of the distal tubule and the collecting duct more permeable to water. If the ADH producing cells in the hypothalamus or the nerve cells that bring ADH to the pituitary gland were destroyed, it would cause this condition to occur. Someone with diabetes insipidus would have an increased urine output and would be constantly thirsty due to the fact that they cannot reabsorb much of the water they consume. Their urine would be very diluted and very light in colour. After comparing the colours of the different urine samples, it was concluded that Sample Y could have diabetes insipidus due to its light colour. The light colour could be a result of the inability to reabsorb water in the nephron which could be linked to diabetes

    The reasoning behind this is that when traveling down the collecting duct the concentration of salt is almost similar both on the inside and in the interstitial fluid. The collecting duct is permeable to water and not salt, so water is drawn out via osmosis, which is determined by Antidiuretic Hormone secretion (3). Whether or not water needs to be conserved determines the amount of ADH that is released. If the hormone ADH is high, then the collecting duct becomes more permeable to water so more water is drawn out which means that less urine volume and it will be more concentrated. If ADH is low then less water is removed and the urine volume is large and more diluted. For the salt group, eating potato chips and drinking the salt solution increased the amount of sodium in the blood, leading to more water reabsorption and water retention. The increased Na in the blood will be filtered into the nephron. The increase makes the sodium transporters not able to reabsorb all of the sodium. Therefore, excess sodium and water will remain in the lumen (3). The excess sodium will be excreted into the urine and eliminated from the body. A substance can remain in the blood depending on the amount filtered into the nephron and the amount reabsorbed or secreted by…

    What will happen to the urine volume and concentration as the solute gradient (concentration) in the interstitial space is increased? Explain!!! (3 points)  It increases because ADH causes water to move out of urine and the more solute there is the more concentrated the urine. 16. Speculate on ways that desert rats are able to concentrate their urine significantly more than humans? (Think: Hormones) (2 points)  They probably produce more ADH to get all the water possible from the urine as there is not a lot of water in the desert. 17. What would be a reasonable mechanism for diuretics? (2 points)  They act by diminishing sodium reabsorption at different sites in the nephron, thereby increasing urinary sodium and water loss. 18. What will happen to the glucose concentration in the urinary bladder as glucose carriers are added to the proximal tubule? Explain!!! (2 points)  Glucose concentration in the urine decreased because the carriers were able to get the glucose across. 19. Predict what will happen to the urine volume (compared to normal) when aldosterone is added to the distal tubule. Explain!!! (2 points)…

    As the lead homicide investigator for this case I had recently learned that the crime lab has concluded that the finger print that was recovered belonged to the boyfriend, they were from a piece of notebook paper found under the body of the victim. Interviews are conducted in criminal cases for the purpose of gathering information from people who have, or may have, knowledge needed in the investigation. (Swanson, Chamelin, Territo & Taylor, 2012) However with the information that was recently learned from the evidence that was collected and analyzed by the crime lab, the interview with the boyfriend would now be conducted as an interrogation. Interrogation as opposed to interviewing is designed to match acquired information to a particular suspect in order to secure a confession; it is the process of testing that information and its application to a particular suspect. By means of interrogation we would be able to eliminate the innocent or identify the guilty. (Swanson, Chamelin, Territo & Taylor, 2012)…

    During this laboratory exercise will identify by the graph given which is isotonic, hypotonic, or hypertonic. The kidneys are a pair of fist-sized organs located outside the peritoneal cavity on each side of the spine. The kidney is a highly specialized organ that maintains the internal environment of the body by selectively excreting or retaining various substances according to specific body needs. The process of urine formation and adjustment of blood composition involves three processes: glomerular filtration, tubular reabsorption, and tubular secretion. The first part of the process of urine formation occurs in the glomeruli which act as filters, allowing water, glucose, salt and waste materials to pass through to the Bowman’s capsule but preventing and red blood cells and plasma proteins to pass through. Reabsorption occurs in the proximal tubules of the nephron. Water, glucose, amino acids, sodium and other nutrients are reabsorbed into the bloodstream in the capillaries surrounding the tubules. Water moves via the process of osmosis: movement of water from an area of higher concentration to one of lower concentration. Tubular secretion is the final step in the process of urine formation which transfers materials from peritubular capillaries to renal tubular lumen and occurs mainly by active transport. ADH is secreted by the posterior pituitary (neurohypophysis) when there is a decrease in water concentration (increase in osmolarity) which will cause an increase in water reabsorption (decrease in osmolarity). ADH most important function is to conserve the fluid volume of your body by reducing the amount of water passed out in the urine. When there is a decrease in serum sodium levels (decrease in osmolarity) the ACTH causes the adrenal cortex to release aldosterone, thereby increasing sodium reabsorption in the distal convoluted tubules of the kidney (increasing osmolarity). Aldosterone also acts on the kidney to reabsorb sodium and water…
