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
