The Respiratory System

The Respiratory System Watch this video to see how respiration works. (Ignore the video question below) Use the information provided in the video you just watched and your prior knowledge to fill in the blanks about the function of the respiratory system. The respiratory system aids in the process of cellular respiration by obtaining one of the raw materials, oxygen, from the environment AND removing the byproduct of carbon dioxide. Respiratory System Diagram Labeling Use the word bank below to label the diagram. **HINT** Diagrams are always labeled from the "owners" perspective; in other words the right and left sides are flipped from your perspective.BronchiolesBronchusDiaphragmEpiglottisLungTrachea Bronchioles Diaphragm Trachea Bronchus Lung Epiglottis Organ Functions Match the structure of the respiratory system with its function. (To answer: click on an orange dot and drag your mouse the to the matching orange circle in the other column.) Trachea A cartilage-ringed tube that carries air to the lungs; "windpipe" Larynx Produces our voice; a.k.a. "voice box" Alveoli Tiny sacs that is the site of gas exchange Lungs The essential organ of the respiratory system Diaphragm Dome-shaped muscle that helps to expand and contract the lungs Interactions with Other Body Systems Use the word bank to fill in the chart about how the respiratory system works with other systems in the body to help us function. Interacting System Relationship Description Skeletal Cartilage is a tissue found in this system. The cartilage helps support the trachea in the respiratory system. Circulatory Capillaries are found in the lungs so that nutrients can be brought into the bloodstream. Nervous This system sends signals to the chest cavity to contract surrounding organs so that there is room for the lungs to expand during inhalation.
