excretion

Removal from the body of the waste products of metabolism.

excretion

any elimination from an organism of unwanted materials, for example, carbon dioxide and nitrogenous substances produced in METABOLISM. It is worth noting that excretory materials must be produced by the organism rather than just pass through it; thus faeces in mammals contain a mixture of excreta (e.g. bile pigments) and undigested gut contents. Compare SECRETION.

Patient discussion about excretion

Q. what is the best thing to do to eliminate or to let it be remove without surgery?I'm afraid but laser mayb ok If I can go for laser where can you suggest coz I'm jobless and can't afford to pay.Or is there some remedy that i can take to melt those stones inside my bladder then they can come out through my waste ?

A. Bladder stones, also called bladder calculi, often form when concentrated urine sits in your bladder. Bladder stones usually need to be removed. If the stone is small, your doctor may recommend that you drink an increased amount of water each day to help the stone pass. If the stone is large or doesn't pass on its own, your doctor may need to remove the stone. Bladder stones are usually removed during a procedure called a cystolitholapaxy. This is done by inserting a small tube with a camera at the end (cystoscope) through your urethra and into your bladder to view the stone. Your doctor uses a laser, ultrasound or mechanical device to break the stone into small pieces and then flushes the pieces from your bladder.
I am not familiar with the cost of such procedure.

Q. skins does excrete oil and keratin what exactly is the whitish cape up that you can squeeze out from underskin

A. It sounds like you refer to sebum, an oily substance secreted by (how surprising :) ) sebaceus glands attached to the hair root. It's important for the skin, although abnormal secretion of it may cause diseases such as acne.

The lower urinary excretion of cefixime in local subjects may be due to environmental or seasonal variation and due to differences in the genetic makeup.
(2006) cats fed with a diet with 0.1% MHA had a lower concentration of postprandial urinary calcium (mmol/L) than cats fed with diets with 0.1% DLM (p<0.10), unlike results reported in our study, which MHA diets increased urine calcium excretion compared with calcium sulfate.
A 56-year-old, 44-kg female with human immunodeficiency virus (HIV) infection was admitted for health care-associated pneumonia (HCAP) with a 24-h urinary creatinine excretion of 739 mg.
The characteristics of participants were assessed using tertiles of the urinary sodium excretion distribution.
The fractional excretion of urea and uric acid was estimated by the formula: fractional excretion ([U.sub.y] x [P.sub.creatinine]/[U.sub.creatinine] x [P.sub.y]), where U = urinary, P = plasma, and y = substance to be calculated.
In this study, we enrolled 35 patients to evaluate urinary excretion of AQP2, AQP5, AQP1, and NKCC2.
The fractional parameter excretion was calculated according to the formula ([urine parameter concentration] x [serum creatinine concentration])/([serum parameter concentration] x [urine creatinine concentration]) x 100%.

The fourth possibility is renal compensation which in turn can be divided into three mechanisms: excretion of free protons (accounting for urine acidification), excretion of phosphate, and excretion of ammonium [19].
Chronic compensation for a high dietary acid load is acknowledged to increase bone resorption and urinary calcium excretion leading to lower BMD and increased fracture risk [13-16].
Conclusion: The prevalence of hypercalciuria and urinary calcium excretion vary for different geographic areas, not only for countries.
