What else can I help you with?
Which substance in not removed from the lumen of the renal tubules by active transport?
Water is not removed by active transport in the renal tubules. It is primarily reabsorbed passively through osmosis following the movement of solutes like sodium and glucose.
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.
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.
What is renal papilla?
The renal papilla is located in the kidneys. The function of the renal papilla is to store urine before it is excreted from the bladder. It contains part of the secreting tubules and the collecting tubules.
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.

What happen to glucose as it passes trough the kidney?
Glucose is typically reabsorbed in the kidney by the renal tubules and returned to the bloodstream. In healthy individuals, little to no glucose is usually found in the urine. However, if glucose levels in the blood are high, as in diabetes, the renal tubules may not be able to reabsorb all the glucose, leading to glucose spilling over into the urine, a condition called 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.
Do the renal tubules empty urine into the renal medulla?
No, the renal tubules do not empty urine directly into the renal medulla. The renal tubules are responsible for reabsorbing water and other important substances from the filtrate, which eventually forms urine that is transported to the renal pelvis before draining into the ureter.
Do the renal tubules empty urine into the renal pelvis?
ureterurethra

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.
What process cause for the absence of glucose and amino acids in urine?
The absence of glucose and amino acids in urine is primarily due to their reabsorption in the kidneys. In the renal tubules, glucose and amino acids are reabsorbed from the filtrate back into the bloodstream through specific transport mechanisms, such as sodium-glucose co-transporters and amino acid transporters. This reabsorption process ensures that these essential nutrients are retained in the body rather than excreted. If glucose or amino acids appear in urine, it may indicate a pathological condition, such as diabetes mellitus or renal tubular disorders.
What are the parts of a nephron?
The parts of the nephron are the renal artery, renal vein, afferent arteriole, glomerulus, bowman's capsule, proximal tubules, distal tubules, loop of henle, renal pelvis, cortex, medulla, peritubular capillaries, and ureter.
Renal pyramids are?
collecting ducts and uriniferous tubules
Vessels that carry blood to the peritubular capillaries?
The main capillaries of the renal cortex which arise from the efferent arteriole after it leaves the renal corpuscle and wrap around the renal tubules, especially the proximal and distal tubules, to supply nutrients and oxygen to the tubules, to carry away wastes from the tubular cells.
