Excretion Excretion is the process by which metabolic wastes and other non-useful materials are eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell. Excretion is an essential process in all forms of life. For example, in mammals urine is expelled through the urethra, which is part of the excretory system. In single-celled organisms, waste products are discharged directly through the surface of the cell.

Causes of HPV Causes of HPV. HPV stands for human papillomavirus. These viruses are the direct causes of HPV and infect the skin or mucous membranes (mucous membranes are the moist, inner lining of some organs and body cavities, such as the nose, mouth, lungs, and stomach). There are actually over 100 different types of HPV. Most are harmless; however, several types can cause precancerous growths or even cancer.

Excretory system The excretory system is a system of organs that removes waste products from the body. When cells in the body break down proteins (large molecules that are essential to the structure and functioning of all living cells), they produce wastes such as urea (a chemical compound of carbon, hydrogen, nitrogen, and oxygen).

Excretory system The urinary bladder is the organ that collects waste excreted by the kidneys prior to disposal by urination. It is a hollow muscular, and distensible (or elastic) organ, and sits on the pelvic floor. Urine enters the bladder via the ureters and exits via the urethra.

What Are Life Processes? It is the creation of energy to keep you active. Excretion refers to the ability to rid the body of waste. It is how energy is produced from glucose and oxygen and the process of removing water, carbon dioxide and other substances from your body. Nutrition means eating, which is important to sustain life.

Human Physiology/Print Version (ĭk-skrē′shən) The elimination by an organism of waste products, such as carbon dioxide and urea, resulting from metabolic processes. Higher animals have specific organs of excretion, such as the lungs and kidneys. In plants and many lower organisms, waste is eliminated by diffusion to the outside environment. excrete verb.

Excretion and the liver The urea and water are released from the liver cells to the bloodstream and transported to the kidneys where the blood is filtered and the urea is passed out of the body in the urine.Urea is very soluble and a small molecule, so it is relatively easily passed out by the kidneys as a solution in water.xcretion and the liver Excretion in mammals Excretion is the removal of potentially harmful or toxic substances from the body. These substances are usually waste materials produced by complex chemical reactions taking place in living cells. Enzymes catalyse the reactions.

- Excretory means basicly to collect waste products and remove it from the body... so when u breath, u breath in O2 (oxygen) and u breath out Co2 (carbon dioxide). so u are removing Co2 Lungs exhale carbon dioxide enriched, moistened, and warmed air which has lost some oxygen to the blood but the lungs also help you move you hand right and left because there is a diaphragm under the lungs that helps control movement.

- The excretory system is responsible for removing metabolic waste products from the body's chemistry. The process of excretion involves the separation of wastes from the body's tissues and fluids, and eliminating them. These waste products are generated as by-products of.

- Excretion. A. EXCRETION. Cellular activities, such as respiration, produce wastes. Some of these wastes are harmful to the body and must be removed. An upset in the balance of body chemicals can lead to serious health problems or death. Excretion is the removal of the wastes of cell activities from the body.

Urogenital system Excretion: Excretion, the process by which animals rid themselves of waste products and of the nitrogenous by-products of metabolism. Through excretion organisms control osmotic pressure—the balance between inorganic ions and water—and maintain acid-base balance. The process thus promotes homeostasis, the constancy of the organism’s internal environment.

Excretion Mammalian excretion [change | change source]. In mammals, excretion is the formation of urine in the kidneys, and expelling carbon dioxide from the lungs. These waste products are eliminated by urination and breathing out respectively.If excretion does not occur in an organism, waste products accumulate, which eventually kill the organism.ammalian excretion [change | change source].

Excretion in Animals, Humans and Plants (with diagram) The removal of metabolic waste products from the body of an organism is known as excretion. The major excretory products are carbon dioxide, excess water, and nitrogenous compounds like ammonia, urea, uric acid, etc. Carbon dioxide and water are produced in the process of tissue respiration.he kidneys produce urine to filter out the waste products, like urea and uric acid, from the blood. Urine leaves each kidney through a tube called ureters. The ureters from both the kidneys are corrected to the urinary bladder that collects and stores urine.

Excretory system The kidneys, considered the main excretory organs in humans, eliminate water, urea, and other waste products from the body in the form of urine. Other systems and organs in the body also play a part in excretion.The respiratory system eliminates water vapor and carbon dioxide through exhalation (the process of breathing out). The digestive system removes feces, the solid undigested wastes of digestion, by a process called defecation or elimination.reter: Tube that carries urine from a kidney to the urinary bladder. Urethra: Duct leading from the urinary bladder to outside the body through which urine is eliminated. The waste-containing fluid that remains in the nephrons is called urine.
