What malfunctioning organ causes glucose in urine?
The malfunctioning organ that causes glucose in urine is the kidneys. Normally, the kidneys filter glucose from the blood and reabsorb it back into the bloodstream. When the kidneys are not functioning properly, they may not be able to reabsorb all the glucose, leading to its presence in the urine, a condition known as glycosuria.
Does the renal artery contain higher levels of glucose than then renal vein?
No, the renal artery carries blood with higher levels of oxygen and nutrients to the kidneys, while the renal vein carries blood with waste products, including urea and carbon dioxide, away from the kidneys. Glucose is typically reabsorbed in the renal tubules, so the levels of glucose are lower in the renal vein compared to the renal artery.
Distinguish between substances that the cardiovascular system transports to cell and substances that it transports away from cells?
The cardiovascular system transports oxygen and nutrients to cells for energy production and maintenance. It also carries waste products such as carbon dioxide and cellular byproducts away from cells for excretion and recycling.
Which body system transports glucose and other substances in the blood to the cells of the body?
The circulatory system, which includes the heart, blood vessels, and blood, transports glucose and other substances in the blood to the cells of the body. Blood is pumped by the heart through the blood vessels to reach different parts of the body and deliver essential nutrients like glucose.
How glucose is excreted?
Glucose is primarily reabsorbed in the kidneys rather than excreted. In healthy individuals, nearly all glucose filtered through the kidneys is reabsorbed in the proximal tubules. However, when blood glucose levels exceed a certain threshold, such as in uncontrolled diabetes, excess glucose is excreted in the urine. This process occurs due to the saturation of glucose transporters, leading to glucosuria.
What two structures transports urine from the kidneys to the bladder?
ureter

How does glucose get into urine?
Glucose is typically reabsorbed by the kidneys and does not appear in urine under normal circumstances. However, if blood glucose levels are too high (hyperglycemia), the kidneys may not be able to reabsorb all the glucose, leading to its presence in the urine (glucosuria). This can be a sign of conditions like diabetes.
Can kidneys function?
While not traditionally discussed, the kidneys’ contributions to maintaining glucose homeostasis are significant and include such functions as the release of glucose into the circulation via gluconeogenesis, uptake of glucose from the circulation to satisfy their energy needs, and reabsorption of glucose at the level of the proximal tubule.
Does the renal artery contain higher levels of glucose than then renal vein?

There is a need for glucose inside a cell but the glucose molecule is too large to pass through the cell membrane. How does the cell solve this problem?
It transports the glucose through transport proteins.

How do liver kidneys and pancreas affect glucose homeostasis?
The liver, kidneys, and pancreas play crucial roles in maintaining glucose homeostasis. The pancreas regulates blood glucose levels by secreting insulin and glucagon; insulin lowers blood sugar by promoting glucose uptake, while glucagon raises it by stimulating glucose release from the liver. The liver stores glucose as glycogen and releases it into the bloodstream when needed, while the kidneys help regulate glucose levels by reabsorbing glucose from the urine and can also produce glucose through gluconeogenesis. Together, these organs ensure stable blood glucose levels critical for overall metabolic function.
Which organ and glands have a role in glucose homeostasis?
liver,kidneys and pancreas
What happens to glucose as it passes through the kidney?
Glucose is typically reabsorbed in the kidneys and returned to the bloodstream. If blood glucose levels are high, the kidneys may not be able to reabsorb all the glucose, leading to its excretion in the urine, a condition known as glycosuria.
