The tiny filtering units of kidney are the nephrons.there are millions of them in our body.they contain a number of network of tubes, cells and canals specialised in transmittingThe kidney is responsible for maintaining fluid balance within the body. The basic structural and functional units of the kidneys are the nephrons. Each nephron is made of intricately interwoven capillaries and drainage canals to filter wastes, macromolecules, and ions from the blood to urine. The approximately 1 million nephrons in each human kidney form 10-20 cone-shaped tissue units called renal pyramids that span both the inner and outer portions of the kidney, the renal medulla and renal cortex.
There are two main parts of a nephron: the renal corpuscle and renal tubule. Renal Corpuscle Structure The renal corpuscle is the initial filtering component of the nephron and is made up of two structures known as the glomerulus and Bowman's capsule. The Bowman's capsule is a double membrane that cups the glomerulus. The glomerulus is a capillary extension, a small network of thin blood vessels, receiving blood from the renal circulation. The glomerular filtration rate is a measure of kidney function.  Renal Tubule Structure Renal tubules are a duct system beginning at the Bowmen's capsule in the cortex, looping through the renal medulla, and returning to the cortex to connect to the collecting duct system. Each renal tubule is divided into a proximal tubule, loop of Henle, and distal convoluted tubule. The proximal tubular has a brush border, that is microvilli, that increases the surface area for absorption. The distal convoluted tubule meets the afferent arteriole of the corpuscle as it joins the collecting tubule; this is called the macula densa.  Nephron Function The blood is filtered and urine formed by the actions of the nephrons. In each nephron, high pressure in the glomerulus pushes water and small dissolved materials into the extravascular space of the Bowman's capsule and into the tubule. The proximal tubule reabsorbs water, salts, glucose, and amino acids to maintain electrolyte levels in the body. The interstitium of, that is the tissue space surrounding, the loop of Henle concentrates salts that will be excreted in the urine, creating a concentration gradient in the medulla. The limbs of Henle's loop are permeable to particular ions (descending, water and some urea; thin ascending, general ions; medullary thick ascending - sodium, potassium, chloride), with the cortical thick ascending limb draining into the distal convoluted tubule. The distal tubule contains cells specialized in active transport and maintains urine and blood pH levels, particularly through the regulation of sodium and potassium.

How do kidneys filter the blood?

Kidneys filter the blood in the body by removing the toxins anddisposing them through urine. This function helps the body to clearany build up of waste within the body, and helps to keep the bodyfrom poisoning itself.

Functional unit of the kidney is known as?

The functional unit of the kidney is the nephron. Each kidney ismade up of 1.25 million nephrons. A doctor specializing in kidneysis a nephrologist.

How many gallons of blood can the kidneys filter per hour?

The kidneys filter about 150 to 180 liters per day, so that would be about 6 to 7.5 liters an hour. . 6 liters = 1.6 US (1.3 UK) gallons . 7.5 liters = 2 US (1.6 UK) gallons See Related Link below ads

How do kidneys filter blood?

Blood enters the kidney through the renal artery. It is thencleaned as it goes through the tiny filters called nephrons.

How does the kidney filter in the body?

The kidney filters by passing high pressure blood through a series of narrower blood vessels in a glomerulus. There are many of these inside a kidney. The action of high blood pressure going into a narrow tube effectively pushes the fluid against the vessel walls, filtering a lot of substances out o ( Full Answer )

Does the liver filter blood as well as kidneys?

Yes, both organs filter blood. Although, they filter blood in different ways, but in many cases work together. The liver picks out chemicals and such that need to be chemically changed for many different reasons.
