Excretion: Human excretory system

The body’s natural defence against pathogens is the immune system. When a germ infiltrates the body, the immune system sends forth specific cells to combat it. However, sometimes the immune system isn’t strong enough to keep a disease from causing major harm or even death to a person. However, there is a way to strengthen […]

Introduction Normal human urine consists of 5 percent solid waste and 95 percent water. Urine formation helps modulate the acid-base balance in the body, including fluid volume and plasma composition. The process of urine formation happens in three basic mechanisms: Glomerular filtration Tubular reabsorption Tubular secretion Osmoregulation, on the other hand, is the physiological process

Introduction Urine formation is a very important process of the body to remove waste and toxic products after filtration. What is the definition of urine formation?  Urine is the human body’s liquid waste that is made up of urea, uric acid, salts, water, and other waste products that are produced by the body’s metabolic activities.

Introduction For their survival, all living beings go through several physiological and biological processes. One of the most fundamental mechanisms for supplying nutrients and energy to cells is metabolism. All living organisms, however, produce new compounds called nitrogenous waste in the form of uric acid, urea, and ammonia as a result of this process. Body 

Animals with ammonotelic properties As soluble ammonia, an ammonotelic organism excretes nitrogenous waste from its body. The ammonia produced as a byproduct or waste is extremely toxic. Because it is highly soluble, it requires a large amount of water for excretion. Example- The majority of aquatic animals, including protozoans, crustaceans, platyhelminthes, cnidarians, poriferans, echinoderms, fishes,

Introduction Urea is secreted as a metabolic waste product in several animals. These creatures are known as ureotelic. The ammonia produced by these organisms is transformed to urea in the liver of animals and then released back into the bloodstream. The kidneys filter the urea, which is eventually expelled from the body. To maintain a

Introduction Uremia is a medical disorder characterised by elevated amounts of the amino acid urea in the blood. Urine contains a crucial component called urea. Uremia is a medical term that refers to the presence of urine in the blood and was used by Pierre Adolphe Piorry to describe a clinical condition linked with renal

Uraemia is a harmful disorder that takes place when waste products build up in the blood. The waste product build-up happens due to reduced kidney function. So, uraemia, by definition, simply means the presence of urine in the blood. In short, we can say that uraemia occurs due to waste product accumulation.  Uraemia impacts the

Haemodialysis is a method of artificial filtering of blood when the kidneys don’t function well. There are three types of haemodialysis. They are Conventional Haemodialysis, Daily Haemodialysis, and Nocturnal Haemodialysis. Haemodialysis is a type of dialysis that uses a dialysing fluid, called dialysate, which is rich in electrolytes. The waste products are exchanged from blood

The kidneys’ job is to the filter blood. If kidneys are damaged due to various causes, they are unable to perform their regular functions, causing toxins to build up in our bodies. Dialysis is a way of filtering blood artificially using a dialysis machine. Dialysis permits people to work and live productive lives for longer periods of time.
