Should ketones or glucose be found in urine?

One of the most common diseases associated with glucose and ketones in the urine is diabetes mellitus.

Normally glucose in the blood is filtered and fully reabsorbed by the kidney so that no glucose appears in the urine. In diabetes mellitus, blood glucose is so high that an excessive amount of glucose is filtered -- so much so that the kidney cannot fully reabsorb it. Consequently, the excess glucose winds up in the urine, a condition called glucosuria.

In normal individuals, blood glucose is kept at a stable level by the actions of insulin. When insulin is present and the body's cells are sensitive to it, glucose from the blood is taken up by the cells, decreasing blood glucose. In diabetes mellitus, however, either insulin is not present, or the body's cells are insensitive to it. Consequently, the cells do not take up glucose. As glucose is one of the cell's major substrates for energy, the cell must use alternative measures to generate energy. One of the major mechanisms is through the metabolism of fats. One of the produces of fat metabolism is a molecule called acetyl CoA, which can be further metabolized to form energy. But in fat metabolism, so much excess acetyl CoA is produced that it overwhelms the enzymes that convert it into energy. As a consequence, the excess acetyl CoA is shunted to alternative pathways that take care of it. One of the pathways is the production of ketone bodies. As a result, ketone levels rise and ultimately can end up in the urine just as glucose did, as described above.

What does a man do if he needs a pee really bad but all of the toilets and urinals are being used?

Depends on where he is, how desperate he is and how rude he is.

There might be a waste basket with a liner he can use, maybe a floor drain he can aim for, or an unused wash basin. Or maybe he's carrying a water bottle or any other reasonably sized drink container he can pee into.

What filters waste from the blood?

Liver.

With the exception of the brain, the liver is one of the most complex organs in the body. It has over 500 functions, most of which are essential for sustaining life.

The functions of the liver include: filtering toxins from the blood , producing important chemicals, such as proteins and hormones, producing blood-clotting agents that can help to prevent excessive bleeding, regulating cholesterol levels in the blood, helping to fight infection and disease, and storing energy for use when the body needs an immediate energy boost.

How do kidneys clean the body?

A short, simple answer is that urine is a by product of bodily waste. Kidneys filter impurities. If the kidneys do not do their job in filtering, there is build up in the renal tubules (an area of the renal system leading to the kidneys) and also in the bloodstream. This causes trouble in the body systemically and, if left untreated, can lead to numerous medical problems. In short, the kidneys are the body's filters. Urine is the after product of our body's waste once the kidney's have filtered it. Urine leaves our bodies as a sterile fluid. Angie RN

Because the digestive system starts at your mouth and goes through the intestines that open at the other end for elimination of wastes from your colon and rectum.

Main role of deamination in nephron is?

deamination, the removal

of the amino group from an amino acid. This is often accomplished

by transamination. The amino group is transferred from

an amino acid to an -keto acid acceptor. The organic

acid resulting from deamination can be converted to pyruvate,

acetyl-CoA, or a TCA cycle intermediate and eventually oxidized

in the TCA cycle to release energy. It also can be used as a

source of carbon for the synthesis of cell constituents. Excess nitrogen

from deamination may be excreted as ammonium ion, thus

making the medium alkaline.
