medulla
the renal medulla contains capillaries and urine forming tubules
Casts are formed in the distal convoluted tubules and collecting ducts of the nephron in the kidney. They are made up of protein or cellular material that becomes trapped in the renal tubules and is then washed out into the urine, where they can be detected.
The tubular structures that carry waste from the kidney are the renal tubules, specifically the collecting ducts. After filtration in the nephron, waste products and excess substances are reabsorbed and secreted through the renal tubules, eventually leading to the collecting ducts. From there, urine is transported to the renal pelvis and then to the ureter for excretion.
The structures that distal tubes flow into are the collecting ducts of the kidneys. The collecting ducts are small tubes through which urine flows into the renal pelvis.
glomerular,capsules,Convoluted tubules ,kidney loops are the parts of Nephron... Nephron is the basic unit of a kidney.... group of nephrons constitute the kidney.. so you can't see all of them as individuals... I think you may have got your answer... Thanks.
Cats have two kidneys, and each kidney contains thousands of microscopic units called nephrons. These nephrons consist of a renal corpuscle, convoluted tubules, and a collecting duct, but they do not form pyramids. Pyramids are specific structures found in the medulla of the kidneys in animals like humans.
medulla
A metanephric kidney is the functional kidney of adult amniotes, that is, the reptiles, birds, and mammals. It occupies a more caudal position in the body cavity and is a much larger, more compact structure containing many tubules. It is drained by a ureter.
Tubules are the tubes running through each little (microscopic) nephrons within each kidney that aid in filtering and collecting of the waste products, and then depending on how much water is in the body it either can reabsorb more water or more salt depending on your electrolyte balance. :-D
Antidiuretic hormone(ADH) reabsorbs water from the collecting tubules of the kidney causing urine to become concentrated.
Renal cortex
because the fluid pressure in the capillaries is higher than that of kidney tubules
