. Update Article NSAIDs and Kidney P Ejaz‚ K Bhojani‚ VR Joshi* Abstract NSAIDs are commonly used drugs. Even with the advent of selective COX-2 inhibitors‚ nephrotoxicity still remains a concern. The adverse effects of NSAIDs are mediated via inhibition of prostaglandin synthesis from arachidonic acid by non-specific blocking of the enzyme cyclooxygenase leading to vasoconstriction and reversible mild renal impairment in volume contracted states. When unopposed‚ this may lead to acute tubular

C 5 types of excretory systems: None in porifera‚ cnidaria Protonephridia in planaria & rotifers Metanephridia in annelids Malpighian tubules in terrestrial arthropods Kidneys (with nephrons) in vertebrates Protonephridia Have flame bulbs‚ tubules‚ and nephridopores. C Flame bulbs selectively filter body fluid to nitrogenous waste. C Fluid collects in tubules and drips outside through the nephridopore. Metanephridia

This essay “Kidneys” is from the book “Strangers Drowning” written by Larissa MacFarquhar‚ which is about kidney donors and how they go on about their lives after the ‘satisfaction’ of saving someone’s life‚ or just for pure altruism. The story clearly states how one of the donors in this piece‚ Paul Wagner‚ didn’t feel as much as a hero afterward. He lived off the attention from the media‚ admiration from the people around him‚ and “had loved telling people that he was donating a kidney to a stranger

the ability of water to move from one solution to another solution through osmosis. Osmotic pressure refers to tendency for a liquid solution to diffuse therefore moving from a lower to higher concentration across a membrane. As it is critical for humans to maintain a regulated osmotic pressure they are able to gain an isotonic solution which would mean that there is no total loss or gain of fluids or salts into the cells of the body. Rather there is a steady and constant flow of substances in and

What is a kidney stone? A kidney stone is a little stone of calcium‚ magnesium‚ or uric acid that has crystallized and precipitates in the renal pelvis (textbook‚ p. 988). Kidney stones can be very painful when having them or trying to pass them. Renal colic or unspecified abdominal pain were the most frequent presenting symptoms of kidney stone disease (Metabolic 3). Then followed by hematuria‚ (Metabolic 4) the presence of blood in the urine. Pediatric urinary stone disease is a relatively infrequent

ensures our body temperature stays at 37°C. Negative feedback: makes sure that all control system changes are reversed. How homeostasis controls body temperature. All mammals have a constant body temperature. This is 37°C for humans. The way heat is lost in a human body is explained in the following way: Volume: Surface Area ratio. This means the bigger a person is‚ the quicker they lose heat as there is more places for heat to escape. So the smaller a person‚ the longer it takes for them

Identify the Problem The kidney is an extraordinary organ. Without its processes‚ human life would be virtually impossible. It is a very well known fact that when individuals consume large amounts of liquid‚ they eliminate much of the liquid through urine. On the other hand‚ when individuals are severely dehydrated very little urine is formed. This certainly illustrates that control mechanisms in the human being can regulate the amount of urine that is formed. When tap water is ingested

A kidney stone is a hard piece of material that is formed from substances in the urine and develops in a kidney. These hard stones may often come loose and move down the urinary tract. If it is small enough‚ it can pass through in the urine with little pain. However‚ the bigger kidney stones can lodge somewhere in the urinary tract‚ get stuck‚ and cause a lot of pain. It can also obstruct the flow of urine. This article explains what causes them‚ and describes several different treatments for them
