PPT-Excretory System Includes kidneys and associated ducts

Excretory and Reproductive systems are closely associated morphologically both in terms of mode of development and use of common ducts This association is primarily due to a common derivation . THINK ABOUT IT. It. ’. s a hot day and you gulp down water. As you drink, you begin to wonder. Where. ’. s all that water going? Will it just dilute your blood, or is something in your body making sure that everything stays in balance?. Excretion, kidneys, and urine….. Excretory System.

The excretory system . collects and removes . wastes from our bodies.. Wastes take the form of solid, liquid and gas.. What parts of the excretory system do we already know? . What parts get rid of wastes?. Excretion is the process of eliminating . waste. .. There are several systems within our bodies that help us to eliminate waste products. . Excretory (. Urinary. ) – eliminates . liquid. waste. Digestive- disposes of . Define terms relating to the urinary system. Describe the two functions of the urinary system. Identify structures of the urinary system. Identify function of at least three structures of the kidney. REGULATION. Excretory & Nervous Systems. Regulation within animal systems requires maintaining . homeostasi. s. - . t. he ability of the body or a cell to seek and maintain stability within its internal environment when dealing with external changes .

Introduction. Every body activity uses . energy. and generates . wastes. . . If waste products were not removed, they would quickly accumulate in harmful proportions.. Some wastes are . poisonous. Why is excretion necessary?. In order for cells to stay alive, they must continually intake water and other molecules.. The cells would continue to get bigger and bigger if they only took in molecules.  is a passive biological system that removes excess, unnecessary materials from the . body fluids.  of an . organism. , so as to help maintain internal chemical . homeostasis.  and prevent damage to the body. The dual function of excretory systems is the elimination of the .
