What is excretion?
vertebrates can accumulate large amounts of waste in their tissues, organs and blood. To avoid harmful substances in the body, the removal of waste is achieved by a process known as excretion. During this process, the mass of waste is discharged by urine, sweat and other means.
The excretion takes place using four body systems. In the kidney's urinary system they work to deprive water and toxins. They also eliminate electrolytes and nitrogen compounds. The lungs that deprive the body of carbon dioxide waste consists of a respiratory lever.
Like the kidneys, the skin helps the body to secrete nitrogen, water and waste for electrolytes from the entire integrated system. Pot excluded from the skin contains waste such as lactic acid and urea. Another purpose of sweat excretion is to maintain body temperature and homeostasis. The digestive system also plays an important role in the excretion process. The intestine is responsible for the removal of bile pigmentation, heavy metal salts and other digestive waste.
Waste exisitionThey are in several forms. Dead cells and sweat are the most common waste excreted. Liquid and solid waste leave the body digestion in the form of urine and feces. Carbon dioxide and other gases secreting lungs are in the form of gas. The lungs also eliminate mucus through mucociliary excretion.
The excretion process is vital for the health and well -being of human beings and other creatures. Waste found in the body is poisonous and can easily lead to death without proper detection. The excretory system finds these waste and also disposes of it, allowing the body to remain healthy and functional.
In plants, the waste does not accumulate as strongly as in mammals and other vertebrates. The excretion method used by the plmravníci usually consists of a simple diffusion of waste gases into the surroundings of the organism. Like humans, vertebrates exclude waste through the skin, lungs and urethra by kidney and lungs.
Waste removal processes fromBodies may fail or stop if the excretory organs fail. Medicines and replacing organs can sometimes correct such disorders. Long manual treatment, such as dialysis, can sometimes be filled when an organ, such as the kidney, fails permanently. If it is not correctly replaced or treated, the excretory failure may lead to severe illness and death.
Many people refer to defecation as excretion. However, the use of the term in this way is incorrect. Although the feces themselves contain waste and its release is part of the excretion process, the defecation itself is not considered to be the removal of waste. Instead, it mainly concerns the removal of impartial food.
