How is glucose found in urine?
Normally your body will hold on to most things that it can use and will remove those that it doesn't. If you are not making enough insulin, glucose will be found in the urine. Insulin is needed to carry the glucose molecule into the cell and if it isn't doing this, the glucose will "spill over" into the urine. Testing will give the doctor an idea if you are making insulin and perhaps you might need to take it.
Which of the choices below exerts primary control over sodium levels in the body?
The kidney exerts primary control over sodium levels in the body by regulating the reabsorption and excretion of sodium ions in the urine. Hormones such as aldosterone also play a key role in controlling sodium levels by influencing the reabsorption of sodium in the kidney.
Can blood glucose level falsely increased in lipemic serum?
Yes, blood glucose levels can be falsely increased in lipemic serum due to interference in some laboratory methods used to measure glucose levels. Lipemic serum contains high levels of triglycerides or fats, which can affect the accuracy of glucose measurements by some glucose assays. This interference can result in erroneously elevated glucose readings.
Explain what effects the changes in insulin concentration have on glucose mobilization during exercise?
During exercise, changes in insulin concentration can affect glucose mobilization by stimulating glucose uptake in muscles. When insulin levels decrease during fasting or intense exercise, there is reduced inhibition of glycogen breakdown and increased release of glucose from the liver to maintain blood glucose levels. Conversely, high insulin levels during rest or fed state promote glucose uptake by tissues, decreasing reliance on liver glucose release.
What are the levels of organization is water carbon dioxide sodium chloride glucose?
Water, carbon dioxide, sodium chloride, and glucose can be organized from lower to higher levels as follows: molecules (water, carbon dioxide, sodium chloride, glucose); cells (e.g., glucose in cells); tissues (e.g., glucose in muscle tissue); organs (e.g., glucose in the liver); organ systems (e.g., glucose in the circulatory system); and organisms (e.g., glucose in a human).
What processes prevent glucose from being excreted in the urine?
Glucose reabsorption in the kidneys prevents it from being excreted in urine. This reabsorption process occurs in the renal tubules, where glucose is actively transported back into the bloodstream. If blood glucose levels are too high, such as in diabetes, the renal threshold for glucose reabsorption may be exceeded and glucose can then be excreted in the urine.
Why in a healthy person does no glucose in collecting duct?
In a healthy person, glucose is typically reabsorbed in the proximal convoluted tubule of the nephron, where nearly all filtered glucose is absorbed back into the bloodstream. By the time the filtrate reaches the collecting duct, glucose levels should be negligible, as the renal threshold for glucose reabsorption is usually met. Therefore, under normal conditions, no glucose is found in the collecting duct because it has already been efficiently reabsorbed earlier in the nephron. If glucose is present in the collecting duct, it may indicate conditions like diabetes mellitus, where glucose reabsorption is impaired.
Which process returns glucose to the blood?
Gluconeogenesis is the process by which glucose is formed from non-carbohydrate sources, such as amino acids and glycerol, and released into the blood to maintain adequate blood glucose levels.
Which renal structure transport glucose?
The proximal convoluted tubule in the kidney is responsible for reabsorbing glucose from the filtrate back into the bloodstream. This ensures that glucose is not lost in the urine and helps maintain normal blood sugar levels.
The regulation of blood sugar is accomplished by the organ called the what?
The regulation of blood sugar is primarily accomplished by the pancreas, specifically through the actions of insulin and glucagon. Insulin helps lower blood sugar levels by promoting glucose uptake into cells, while glucagon helps raise blood sugar levels by promoting the breakdown of stored glucose.
Do nephrons form urine?
Blood is filtered through the bowmans capsule (large proteins are left in the bloodstream). The fluid that remains in the nephron after filtration is called the filtrate.The filtrate enters the proximal tubule. Glucose, amino acids, and water are secreted (released into bloodstream). The filtrate begins to darken with less water in it.The filtrate then moves on to the Loop of Henle. On descent, water leaves the filtrate by osmosis and on ascent; sodium and chloride leave the filtrate by active transport. This is necessary to produce concentrated urine. The loop of henle becomes less permeable as it goes ascends so less sodium and chloride leave the filtrate as the filtrate makes its way up the loop.The filtrate then moves on to the Distal Tubule where pH is regulated and sodium potassium, and calcium levels are controlled. The filtrate becomes more concentrated here.The filtrate then moves into the Collecting Duct. The collecting duct is what connects the nephrons to the ureter. It participates in electrolyte and fluid balance through reabsorption and excretion.(I did this for a Grade 12 Biology lab so this is just a collection of stuff I got off the internet from various good sources! anybody else who was just as confused as I was when I got this question!)
What results from increased levels of aldosterone?
Increased Na+ reabsorption

What hormone reduces blood glucose levels and what hormone raises blood glucose levels?
Glucagon is the hormone that raises blood glucose levels.
Do the kidneys control the levels of water in the blood?
Yes. It either excretes of reabsorbs sodium, potassium H+ ions bicarbonates glucose and a lot more.
Why is glucose completely reabsorbed?
The proximal convoluted tubule.The Loop of Henle is the part of the nephron that contains the basic pathway for liquid. The liquid begins at the Bowman's capsule and then flows through the proximal convoluted tubule . It is here that Sodium, water, amino acids, and glucose get reabsorbed. The filtrate then flows down the descending limb and then back up. On the way it passes a major bend called the Loop Of Henle. This is located in the medulla of the kidney. As it approaches the top again, hydrogen ions (waste) flow into the tube and down the collecting duct.
Does glycogenolysis increase blood glucose levels?
Yes, glycogenolysis is the breakdown of glycogen into glucose, which can increase blood glucose levels.
