Like most nutrients, glucose sugar is absorbed into the blood stream through the walls of the small intestine from the food one eats.

Why sugar does not appear normally in urine?
The nephrons (filtering units in the kidney) actively reabsorb glucose from the urine. Up until a blood sugar of about 200, there should normally be no glucose found in the urine. Glucose in the urine (also called glycosuria), can be seen in diabetes and other conditions that cause an increased blood glucose. There are also some conditions that prevent the nephron from reabsorbing glucose filtered in the kidney.
5 percent glucose solution is isotonic for red blood cell if red blood cell are kept in 2 percent glucose solution what will happen to the cells. what such a solution called?
2% glucose solution is considered as a hypotonic solution for that the solution will enter the semi-permeable membrane of the red blood cells causing the cells to explode or burst. Why? It's because RBCs have a higher concentration inside it than that of the 2% glucose solution so the solution will enter the cells.
Is fat is the primary fuel for the brain?
Glucose is the only fuel normally used by brain cells. Because neurons cannot store glucose, they depend on the bloodstream to deliver a constant supply blood glucose. A process called glycogenolysis can break down glycogen stored in the liver to glucose. This then travels in the blood to your brain or muscles in need of glucose.
When blood glucose level rises the pancreas secretes insulin and as a result blood glucose level declines when blood glucose level is low the pancreas secretes glycogen and as a result blood glucose?
Catalytic feedback
What hormone is involved in blood glucose regulation?
There are two hormones that regulate blood glucose levels. One is insulin. This horemone "carries" glucose into the cell. No glucose and the cell starves and the glucose levels get higher in the blood. The second hormone takes glucose out of liver storage and increases the glucose in the blood. These two are a feedback mechanism that keeps the levels in a normal range.
Normally when the concentration of glucose in the blood falls below a certain level stored glucose reenters the blood until the original concentration of blood glucose is part of the process known as?
homeostasis
How does the nephron normally handle glucose in the blood?
Nephrons are located in the kidneys. Each kidney has about one million nephrons. The nephrons filter your blood. Glucose is filtered through the nephrons just as everything else in your body is filtered.
In homeostasis what is blood glucose range between?
Normally, in mammals the blood glucose level is maintained at between 3.6 and 5.8 millimoles per litre. In humans, normal blood glucose is about 90 mg per 100ml of blood--that's about 5 millimoles.
Which of the following substances is normally NOT found in urine?
If you are talking about three substances that are normally found in blood but not in urine, they are leukocytes, erythrocytes and glucose.

How does glucose enter cells from the blood stream?
Glucose is basically sugar so i would say by mouth.
Where does glucose and calcium enter the blood?
All nutrients we have taken are absorbed into the blood in the small intestine. The excess are stored in the liver from where if required is again absorbed into the blood.

What is glycogen and why is it important for our energy?
Glycogen is the type of carbohydrate which our body uses for storage. It is normally stored in muscles. It is important as a 'reserve' source of energy for our body. When the blood glucose level decreases, insulin converts glycogen into glucose so as to bring it to the normal blood glucose level.
Do glucose and water enter the filtrate?
no glucose does not
What does insulin cause the liver to change glucose into?
Insulin causes the glucose in your blood to enter the cells for energy. It does not cause the liver to change glucose into anything. Your liver does, however, store extra sugar in the form of glucagon.
What happens when the blood goes to the kidneys?
When the blood goes to the Kidneys, you would feel a lot of pain. Normally, blood isn't supposed to enter the Kidneys.
