The Human Body: The Respiratory System Vocab (rhs)
Respiratory System
acquisition of oxygen and elimination of carbon dioxide: consists of airways, lungs, and respiratory muscles to mediate movement of air in and out of the body
Ventilation
act of supplying fresh air
Inspiration
breathing in
Expiration
breathing out
Alveoli
bring new oxygen from air into blood stream, exchanges oxygen for waste (Co2) by red blood cells to complete oxygenation
Asthma
chronic disease that affects your airways and can't be cured
Tuberculosis
common and deadly infectious disease caused by myobacterium
Carbon Dioxide Poisoning
condition where there is too much carbon dioxide in the blood (hypercapnia)
Laryngopharynx
connects the esophagus to the larynx
Nasopharynx
connects to the pharynx
Visceral Pleura
deep layer that covers the lungs
Lung Cancer
disease where tissue in the lung grows out of control
Respiratory Bronchioles
divide into several alveolar ducts
Nasal septum
divides the nasal cavity into left and right halves
Pleural Membrane
encloses and protects the lungs
Pharynx
funnel-shaped tube located in the throat, starts at internal nostrils and extends to larynx and contains tonsils
Pneumonia
illness of lungs and respiratory system in which the alveoli become inflamed and flooded with fluid
Bronchi
large air tubes leading from the trachea to lungs which convey air to and from lungs; (primary, secondary, tertiary, right, and left bronchioles)
Parietal Pleura
layer that lines the wall of the thoracic cavity
Oropharynx
lies in the back of the throat
Emphysema
long-term, progressive disease of the lung, causes shortness of breath
Internal nostrils
opening into the pharynx
External nostrils
opening of the nostrils
Lungs
pair of cone shaped organs in thoracic cavity that inflate and deflate as respiration occurs
Larynx
short passage that connects pharynx and trachea (voice box)
Lobules
small compartment associated with a segment of the lungs
Terminal Bronchioles
subdivide into microscopic branches called Respiratory Bronchioles
Alveolar Ducts
surrounded by alveoli
Trachea
tubular passage of 16-20 C-shaped rings of cartilage which extends from larynx to fifth thoracic vertebrae where it divides into primary bronchi (windpipe)
Nose
warm, moisten and filter incoming air, receives smell and modifies speech
Carbon Dioxide Waste
waste that is transported back through lungs and up windpipe and released when exhaled
