CTC Respiratory Syst

Flash cards for CTC Respiratory System Final

The exchange of air between the atmosphere and the air sacs(alveoli) of the lungs. Pulmonary Ventilation
Occurs in the lungs as oxygen diffuses from alveoli into the blood & co2 diffuses out of the blood to be eleminiated. External Gas Exchange
Occurs in the tissue as oxygen diffuses from the blood to the cells. Internal Gas Exchange
An intricate arrangement of spaces and passage ways that conduct air into the lungs. Respiratory System
Three projections on the lateral walls of each nasal cavity.Greatly increase the surface area of mucous membrane over which travelson its way through the nasal cavities. Conchae
Nasal lining and cilia help with the following: 1.)Filters out foreign bodies such as dust particles and pathogens.2.) Helps to warm the air3.) Air is moistened by liquid secretions4.) Serves as an air distributor.
Small cavities lined with mucous membrane in the skull bones. Sinuses
Throat- Carries air into the respiratory tract and carries foods and liquids into the digestive system. Pharynx
Space between the vocal cords. Glottis
The leaf shaped cartilage that covers the larynx during swallowing. Epiglottis
Coomonly called the windpipe. Tube that extends fromt he inferior edge of the larynx to the upper part of the chest superior to the heart. Trachea
Trachea is lined by what? Respiratory Mucosa
These epithelial cells have cilia to filter out impurities and to create fluid movement within the conducting tubes. The cilia beat to drive impurities toward the throat, where they can be swallowed or eliminated by coughing, sneezing or blowing the nose.
Tiny air sacs where most gas exchange takes place. Alveoli
A substance that reduces surface tension of the fluids thast line the alveoli. Prevents the collapse of alveoli and eases lung expansion. Surfactant
Major Muscle of Breathing. Seperates thoracic cavity from abdominal cavity. Diaphragm
Inspiration; Drawing of air into the lungs Inhalation
Expiration; Expulsion of air from the lungs. Exhalation
High To Low Concentration of a gas Diffusion
Temporary cessation of breathing. Normally occurs during deep sleep. Apnea
Labored breathing Dyspnea
A minor structural defect when one nasal space is considreably smaller than the other. Deviated Septum
Any infection that is confined to the nose and throat. Upper Respiratory Infection (URI)
Obstruction of normal airflow to lungs, reducing exchange of oxygen and carbon dioxide. Chronic Obstructive Pulonary Disease (COPD)
Crib Death; Baby stops breathing during sleep. SIDS
Guidelines to reducing SIDS: 1.) Place baby on back2.) Smoke free Environment3.) Firm, flat baby matress4.) Avoid over heating baby with room air.
Time when baby gets brown fat. From Birth to 6 months.
