Definitions &Translations Excretion. Excretion is the process by which waste products of metabolism 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.

19. Respiratory and Excretory System Excretion is the process of removing wastes from the body. The organs of the excretory system are also parts of other organ systems. For example, your lungs are part of the respiratory system. Your lungs remove carbon dioxide from your body, so they are also part of the excretory system.

Urine Most animals have excretory systems for elimination of soluble toxic wastes. In humans, soluble wastes are excreted primarily by the urinary system and, to a lesser extent in terms of urea removed, by perspiration. The urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The system produces urine by a process of filtration, reabsorption, and tubular secretion.

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.he 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).

Human Physiology/Print Version Urine (from Latin Urina, ae, f .) is a liquid by-product of the body secreted by the kidneys through a process called urination (or micturition) and excreted through the urethra. Cellular metabolism generates numerous by-products, many rich in nitrogen, that require clearance from the bloodstream.

Tips For Caring For Saguaro Cactus These cacti are native to and only grow in the Sonoran Desert. Saguaro are not found in the entire desert but only in areas that don’t freeze and at certain elevations. The freezing point is one of the most important considerations of where do Saguaro cactus grow.The cactus plants are found from sea level up to 4,000 feet. If they are growing above 4,000 feet, the plants survive only on south slopes where there are fewer freezes of shorter duration.Saguaro cactus plants are important parts of the desert ecology, both as habitat and as food.he cactus is a very slow growing plant, which may add only 1 to 1 ½ inches in the first eight years of life. The Saguaro grows arms or lateral stems but it may take up to 75 years to produce the first one.

Whats the main function of the excretory system? to excrete is to get rid of something from your body. In this case you are probably referring to the end of the gastrointestinal system and possibly the urinary system. Either way, they get rid of wastes in the body that if built up would cause harm to the rest of the body.
