The Respiratory System group of organs that take in oxygen and get rid of carbon dioxide

Respiration The process by which a body Gets and uses oxygen Releases carbon dioxide and water Two parts of the process Breathing: inhaling and exhaling Cellular respiration: chemical reactions that release energy from food

Respiratory System Organs Involved: Nose Pharynx Larynx Trachea Bronchus Lungs Diaphragm

Pharynx Passage from the mouth to the larynx and esophagus

Larynx Area of the throat that contains the vocal cords and produces vocal sounds

Trachea Tube that connects the larynx to the lungs

Bronchi Two tubes that connect the lungs with the trachea *bronchus = 1 tube

Alveoli Tiny air sacs of the lungs where oxygen and carbon dioxide are exchanged

Diaphragm Dome shaped muscle beneath the lungs

Cellular Respiration Oxygen is used by cells to release energy stored in molecules of glucose

Respiratory Disorders Diseases of the lungs: Asthma Emphysema Severe Acute Respiratory Syndrome (SARS)
