| Topic 17-3 The Excretory System |
| Objectives Explain how waste products are formed and removed by the body. Describe how the kidneys act as a filtering system or the blood. |
| State Goals |
| Classwork-Homework
On the Board Excretion: removing waste products from the body Urea: chemical that comes from the breakdown of proteins Kidney: organ that removes waste products from the blood Urine: watery fluid that contains urea and other wastes Ureter: tube that carries liquid waste from the kidneys to the bladder Urinary Bladder: organ that stores liquid waste Urethra: small tube urine uses to leave the bladder Nephron: filtering factories that remove wastes from blood and make urine

Body Quest Group activity to create a presentation about one of the body's
systems. 10 different systems. Presentation planner could be an individual
asignment. |

| Levels of Organization In unicellular (single-celled)
organisms, the single cell performs all life functions. It functions independently.
However, multicellular (many celled) organisms have various levels of organization within
them. Individual cells may perform specific functions (causing a division of labor) and
work together for the good of the entire organism. The cells become dependent on one
another. Explore Cells, Tissues, Organs, Organ Systems, and Organisms. |
