Although ultra filtration in the kidney filters wastes such as nitrogenous waste products in the glomerulus from the blood, it also filters nutrients such as glucose and amino acids. Hence, the loop is surrounded by blood capillaries so that previously ultra filtrated nutrients such as amino acids, glucose, and other nutrients can now be reabsorbed back into the bloodstream by diffusion and active transport and not travel down the further kidney tubules which lead to the bladder and later be expelled in the form of urine.

What is the name of the capillaries that surround renal tubules?
peritubular capillaries
What are blood vessels called that surround the nephron loop?
Renal capillaries, aka the glomerulus, where nitrogenous wastes and excess water in the blood plasma diffuse over to the nephron to be filtered and excreted.
Why do you think capillaries surround the long tubules of nephron?
The kidney's function in filtration. The renal tubules located with in the kidney's and also known as nephrons, are the functioning units of the kidney's. Blood carries nutrients and waste. The renal tubules are surrounded by a capillary network so the blood can expel the waste material that is collects from the body. the renal tubules also replace nutrients and water that is still needed back into the capillaries.
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.
What does nephron consist of?
The glomerulus and the tubules.
What surrounds the tubules of the nephron?
tracheae
What capillary surrounds the tubules of the nephron?
tracheae
Which group of capillaries found in a nephron?
The glomerulus
What does peritubular capillaries do?
This capillary network surrounds the tubules and plays an important role in secretion and reabsorption, plus it delivers oxygen to kidney cells.
Explain Why fluid flows from the capillaries of the kidneys into the kidney tubules?
because the fluid pressure in the capillaries is higher than that of kidney tubules
Trace the flow of blood through the nephron?
the flow of blood through the nephron is : enters through the afferent arteriole, then flows through the glomerulus and into the efferent arteriole. Blood then enters the peritubular capillaries and the vasa recta and then flows through the cortex and medulla of the kidneys close to the tubules Answer: so the flow is afferent arteriole, efferent arteriole, peritubular capillaries, vasa recta
What are the collection capillaries at the beginning of the nephron?
glomerulus
