Describe the process of ultrafiltration in the tubules of the kidneys?

It is a process of membrane filtration. Industrial term generally refer to the membrane filtration to extend of macro-molecule like protein but not fine enough to separate ion like sodium and calcium. Many market application of ultrafiltration as water pretreatment before the process of Reverse Osmosis, thickening of solvent/emulsion, waste water recover etc.
Example process of immerse hollow fibre ultrafiltration for waste water recovery: the fibre is immerse in the waste stream and the suction pressure drawn water pass fibre membrane to the inner hollow tube. The surface of membrane will need constant cleaning by purging out the media sheeting over the fibre surface. The end result is portion of recovered water and very concentrated waste stream that will be proceed to any future treatment and discharge.

∙ 11y ago- Microscopically, the kidney is composed of over one million nephrons.
- Each nephron is made up of several parts. The blind end of the nephron is pushed in on itself to form a cup-like structure called Bowman's capsule.
- Blood from the renal artery flows through an afferent arteriole, into the glomerulus, a capillary bed that is situated inside the Bowman's capsule.
- The blood in the glomerulus is under pressure and the capillary walls are fenestrated (perforated) to allow blood plasma through.
- The basement membrane of the Bowman's capsule has an irregular network of slits, so that much of the fluid from the blood filters into the capsule, leaving behind large proteins and whole cells, which are too big to pass through.
- Thus, the basement membrane acts as the dialysis membrane where ultrafiltration occurs.
- From the Bowman's capsule, the glomerular filtrate passes into the proximal convoluted tubule.

What are nephritis and nephrosis?
Nephritis is inflammation of the kidneys or the interstitial tissues surrounding tubules. Nephrosis is a type of nephropathy that does not involve inflammation but is a degenerative disease of the renal tubules.
What is the seminferous tubules function?
to produce sperms by the process of spermatogenesis
Does spermatogenesis take place in the testes inside the seminiferous tubules?
Spermatogenesis is the process in which the male germ cells undergo meiosis. The process begins to take place in the testes inside the seminiferous tubules.
What is the difference between secretion and excretion?
AnswerI think you are referring to physiology, like the kidneys, right? In that case... Secretion is an active process. In the kidney tubules, somethings, like K+ is secreted from the peritubular capillaries, into tubular cells, and then out into the lumen to mix with the fluid.Excretion is passive. What is excreted by the kidneys is everything that is not reabsorbed and what is secreted. So that means, after all the re-absorbing and secreting processes of the cells, everything that's left in the tubules is excreted into the urine.
The activity of the kidneys is controlled by hormones and by the?
The activity of the kidneys is controlled by hormones which have been released by a gland in the brain and by the composition of the blood.The kidney, better yet, a kidney nephron has three main functions: ultrafiltration, in which contents of the blood are filtered according to their size (Bowman's Capsule); reabsorption, in which needed substances (water, glucose, amino acids, some salts; unneeded: urea, uric acid, some salts) diffuse (by active transport) into the venule end of a capillary bed (renal tubules and, partially, Henle's Loop as well as the collecting duct); osmoregulation, in which ADH (antidiuretic hormone) is released by the pituitary gland in the brain (renal tubules and, partially, Henle's Loop as well as the collecting duct).The kidney has more than one activity, so several things perform the activities.
How do you describe a nephron?
The nephrons are found in the kidneys and are small tubules that are responsible for filtration. There are approximately one million nephrons per kidney.
What is the name given to the tube systems in the kidneys?
renal tubules
In the kidneys the tiny tubules that produce urine are called?
nephrons
What kind of epithelial tissues are the tubules of the kidneys?
simple cuboidal
Where does the reabsorption of glucose primarily occur in the kidneys?
in the proximal tubules
What structures filter blood in the kidneys?
The structures are the glomerulus and tubules.
The lining of the smallest tubules in the kidneys is composed of?
epithelial tissue
Capillaries coming from the tubules in the kidneys merge to form small?
TUBES
Capillaries coming from the tubules in the kidneys merge to form a small?
TUBES
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
What are nephritis and nephrosis?
Nephritis is inflammation of the kidneys or the interstitial tissues surrounding tubules. Nephrosis is a type of nephropathy that does not involve inflammation but is a degenerative disease of the renal tubules.
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.
