Respiratory and Excretory Systems Respiratory System: Oxygen Function: gas exchange, bring _______to the Carbon Dioxide blood and remove ________________ from the blood Organs: Filters Warms and moistens air 1. Nose: _______, ______, Cartilage 2. Trachea: protected by ________, contains the vocal cords Epiglottis: covers trachea when swallowing food 3. Bronchi: two branches that lead to the Lungs _______ Respiratory System: 4. Lungs: made up of ______ Alveoli where gas exchange occurs ( oxygen Enters and carbon dioxide _________ Leaves _______ the blood) 5. Diaphragm: muscle that controls Breathing _______________ Diagrams: • Respiratory and Circulatory systems work together by the blood bringing carbon dioxide to the lungs to be exhaled, and the lungs taking in oxygen and giving it to the blood to be transported throughout the body. Emphysema: a disease that reduces the Alveoli number and elasticity of ___________ Nonsmoker Smoker Excretory System: Waste Function: remove ____________ Organs: Carbon Dioxide 1. Lungs: removes ____________ 2. Large Intestine: removes Solid _______waste from the digestive system 3. Skin: removes ________ Water and heat Amino 4. Liver: removes excess _________ acids and worn out _____ RBC (Red Blood Cells) 5. Kidneys: produce urine to remove ________, salts and nitrogen wastes Water Lungs are a respiratory organ because they take in oxygen and an excretory organ because they get rid of carbon dioxide • Human Kidney Diagrams: Skin Lg Intestine Lungs Kidney Liver Describe the exchange that occurs with the circulatory system and the body cells. The circulatory system delivers and gives the body cells oxygen and nutrients as it takes away carbon dioxide and other wastes and delivers them to the excretory organs What would happen if your excretory system didn’t work and why? Your cells would start to die because waste is toxic Review - Electricity • Electricity is due to moving charges • Like charges repel (two positives or two negatives) • Opposite charges attract (Positive and negative) • Electricity can travel through conductors (metals) • Electricity can not travel through insulators (plastic, rubber, glass)
