  1. Excretory System By Katie Ust

  2. function • Rid of waste, chemical build up, and useless cell byproducts • Maintain balance

  3. Types of Nitrogenous Waste • Ammonia – produced by aquatic animals because only low concentrations can be tolerated • Urea – produced by mammals, adult amphibians, sharks in vertebrate liver • Uric acid – produced mainly by insects, reptiles, and birds because it requires little water loss

  4. Excretory processes Filtration reabsorption Renal tubule Solutes and water removed from tubular fluid and transported into blood • Renal corpuscle • Filters blood

  5. Excretory Processes Secretion excretion Rids the body of unnecessary wastes • Transfer of material from peritubular cavities to renal tubular lumen • Active transport

  6. nephritis • Inflames nephrons • Caused by exposure to chemicals and toxins • Symptoms include swelling from accumulated fluid, urine suppression, and a pale complexion

  7. Kidney stones • Crystals are formed around foreign material • Symptoms include pain in side or back during urination • Pain varies case to case, but can be very serious • Can potentially block ureters and must be removed by doctors
