what is the difference between waste material filtered by the kidneys & the waste material of the digestive?

im studying the digestive system right now, so i'll have a go at this question (u may want to chec accuracy).\nthe cell gets the carbon it needs via the blood supply. when we eat, all the nutrients are broken down and molecules such as hydrogen, oxygen and carbon are filtered into the blood stream so that they can be passed on to all the cells in th body.\n\ndoes that help?

Protein contains nitrogen. When protein is broken down and digested, it creates ammonia from the nitrogen. Ammonia is toxic, so the body must get rid of it quickly. The kidneys convert the toxic ammonia into the less toxic urea, which then gets converted to urine.\n\nHigh protein just means the kidneys have to work harder. Many dieticians assume that working the kidneys harder could cause kidney disease. However, there have been no published studies which have shown high protein diets lead to kidney failure, even in competitive bodybuilders. You may want to also keep in mind that about 50% of protein ingested gets burned up as energy, so at some point with increased protein your $40 bottle of whey protein is doing nothing more than a couple of slices of bread.\n\nJohn

Water, urea, sodium, potassium and metabolized waste products.  Urea is the main reson we have to pee, it is the way we get rid of excess nitrogen from breaking down amino acids.  Many drugs such as tylenol are excreted in the urine also, which is why you have to take more every 4 hours.

B. the bloodstream\n\nThe glomerular filtrate is nearly - all resorbed in the tubules; only a teeeeeny % of the water, glucose, human serum albumin and salts are excreted in urine.

I think that it goes along the same lines as the reason we get stomach craps during exercise. The majority of blood is directed to the muscles, not the internal organs. Digestion stops during exercise because the majority of blood is directed to the muscles; I am sure that the same goes for the kidneys. Also this happens when the sympathetic nervous system is activated.

excretory-filters the blood of toxic nitrogenous wastes from amino acid digestion, specifically urea, ammonia and uric acid in verbebrates. Kidney primarily does this job. It also maintains electrolyte and water homeostasis\n\nnervous- transmission of motor, sensory and integrative nerve impulses and action ptotentials throughout the body via brain, spinal cord and nerves to assist in homeostasis of many systems\n\nendocrin- production and secretion of hormones to be sent thru the blood to all cells of the body; works with the nervous system to maintain many forms of homeostasis\n\ndigestive- ingestion, mechanical and chemical digestion and absorption of nutirents (proteins, fats, carbs converted to amino acids, glucose, fatty acids) so that cells can utilize the smaller molecules for human metabolism, growth and misc homeostatic mechanism; digestive system will then eliminate any non-digested, non-absorbable wastes.

Once the body's digestive system extracts all of the nutrients from the foods you eat it disposes of what is left or not needed by the body...thus it is considered waste and the body must have a way to flush the waste out!

Oxygen diffuses from the lungs into the blood.  Nutrients from the intestines into the blood.  In the kidneys water and various molecules diffuse in all sorts of complicated ways that end up condensing the waste products in the urine and reabsorbing a lot of the water.\n\nIf you want to be really flashy, there are loads of molecules that diffuse through cell membranes and do various things, but you'd have to look these up as I can't think of any good examples off the top of my head.

urine contains urea, which is a nitrous acid that is digested out of the bloodstream. when the urea mixes with the toilet water, it foams.

Ok, I'm not one to talk sh** here, but here we go...\nFeces goes through your intestines which have bacteria in them to help break down food. The kind in your intestines, stay in your intestines, and help to maintain your health. NOW- When those bacteria get into any other part of your bod, it's very bad because they release toxins, and other stuff into you that make you quite ill. I mean we naturally have E-coli in our intestines, but it's fatal if you have an E-coli infection. \n\nUrine on the other hand is sterile. You can drink it, but I don't know why on earth you would. Just because its sterile meaning without bacteria and germs, doens't mean that it doesn't still have other toxins and body waste in it. So, uh yuck, don't do it. \n\nAlways, always, always wash your hands after handling body waste. Diseases and other illnesses can still be passed on even if it was only urine...like I said it still has bad stuff in it. \n\nAnd as for the pig thing...I don't know why they weren't sick.

The kidneys . They discard electrolytes through a membrane that the body doesn't use such as uric acid and keep those that the body uses like water. Other filters in the body are lungs, skin, liver,  and spleen

No atleast we need one\n\nThe kidney is a very important organ, and the most obvious function is that it excretes wastes that we produce from our diet and from our metabolism. What's less obvious is that it's the most important organ that controls the composition of the body fluids. In addition, it does produce a number of hormones that deal with body function. \n\n\nThe kidney is a filtering organ, so blood is delivered to a very unique apparatus in the kidney called the glomerulus, and there, because of pressure dynamics, a component of the blood is filtered across the membrane, and the first process of creating the urine develops. In this segment of the kidney, in the glomerulus, the composition of that fluid is very similar to blood. The fluid passes through a series of tubules in a structure called the nephron, and there it's modified, heavily modified. A variety of things are reabsorbed that we need, and a variety of toxins are concentrated until the end of the kidney, the end of that nephron segment, drains into something called a papilla, then into the ureter, and then the bladder, and we have what we term "urine," which is a fluid rich in toxic wastes that is excreted. \n\nsuppose you drink a bottle of orange juice. The body sees a sudden excess of an element called potassium, so the kidney has sensors which look at the body fluid going through the kidney as plasma, and it detects that the plasma's potassium has gone up, and it immediately increase the excretion of potassium so everything comes back to normal.

The liver puts some compounds into the bile, which is dumped into the gut and excreted in the stool.\n\nThe lungs exhale things that can go into gas phase from the blood stream into the alveoli--like the sulfenic acid derivatives that make garlic and onions cause your breath to smell wretched.\n\nSkin does its excretion by putting material into your sweat.\n\nNote that the liver, the kidneys, the skin and even body fat also metabolically modify things (chemically alter them), which not only deactivates them (or in some cases, activates them) but also makes them more easily excreted by the liver or the kidney, which are the primary systems that get rid of such things.\n\nThat help?

The two kidneys of humans are located behind the abdomen.  The kidneys regulate how much water, sodium, potassium, calcium, and phosphate are in the blood.  The kidneys also remove waste products from the body such as uric acid.  Each kidney is filled with capillaries wrapped around very tiny nephrons which filter the blood.

not for an extended period of time. Poop has had all of the nutrients already filtered out and used by the body, it is just the waste product left over and has minimal nutritional value. It could possibly be recycled once or twice for the left over kernels that did not get digested the first time through.

Do you mean reabsorption of water?\n\nFor human, reabsorption of water occurs at the large intestine where processed leftovers its water and moisture that hadn't been fully absorbed and digested is bein' extracted.

The digestive tract is complete and ciliated, with a mouth, anus and complex stomach. The pattern of the stomach varies according to the mollusks diet.  Food is taken up by cells lining the digestive glands arising from the stomach, and then is passed into the blood.  Undigested materials are compressed and packaged, then discharged through the anus into the mantle cavity and are carried away from the animals in the water currents.  This packaging of wastes in solid form prevents fouling of the water passing over the gills. \n        Excretory functions are carried out by a pair of nephridia, tubular structures that collect fluids from the coelom and exchange salts and other substances with body tissues as the fluid passes along the tubules for excretion. The nephridia empty into the mantle cavity.
