|
Ventilation
|
Movement of air in and out of the lungs, also known as breathing.
|
|
|
External Respiration
|
Exchange of oxygen and carbon dioxide between the lungs and circulatory system.
|
|
|
Internal Respiration
|
Exchange of oxygen and carbon dioxide between the blood in the circulatory system and the body cells.
|
|
|
Cellular Respiration
|
The use of oxygen by the cells and the subsequent production of carbon dioxide as the waste gas to be expelled from the body.
|
|
|
Organs of the Upper Respiratory Tract
|
Nose, Nasal Cavity, Pharynx, and Sinuses.
|
|
|
Organs of the Lower Respiratory Tract
|
Larynx, Trachea, Bronchi, Lungs, Internal Lung Structures, and Ancillary Structures.
|
|
|
Nasal Conchae
|
3 Curved, shelf-like bones that project medially from the lateral wall of each nasal cavity; supported by the cancellous bone. (scroll-like appearance)
|
|
|
Paranasal Sinuses
|
-Maxillae
-Frontal -Sphenoid -Ethmoid |
|
|
Pharynx
|
Throat; divided into 3 sections,
- Nasopharynx - Oropharynx - Laryngo Pharynx |
|
|
Larynx
|
Voice Box; Contains vocal cords, connects the pharynx to the trachea, and functions as part of the air passageway.
|
|
|
Trachea
|
Windpipe; 20 C-Shaped rings of hyline cartilage.
|
|
|
Epiglottis
|
Closes over the opening of the larynx to prevent food from entering.
|
|
|
Sellick's Maneuver
|
Cricoid pressure is performed to reduce the risk of aspiration from a patient undergoing general anesthesia.
|
|
|
3 Cartilages
|
- Thyroid
- Criciod - Epiglottic |
|
|
3 Paired Cartilages
|
- Arytenoid
- Corniculate - Cuneiform |
|
|
Bronchi
|
Located withing the mediastinal space, it bifurcates into each lung.
|
|
|
Pleural Cavity
|
The space within the thorax that contains the lungs and pleural membranes.
|
|
|
Lungs
|
Conical space, spongy, elastic-like tissue;
Right has 3 lobes Left has 2 lobes |
|
|
Alveoli
|
Smallest structures of the lung; here the exchange of gases occures.
|
|
|
Oral Healing
|
Heals well without suture
|
|
|
Healing in Pharynx
|
Tissue not needed to be transplanted.
|
|
|
Healing in Trachea
|
2nd Intention healing along with loose sutures.
|
|
|
Bronchus & Lungs
|
Tight suture as not to let the air out.
|
|
|
Inhalation & Exhalation
|
Serous fluid prevents separation, preserves inter pleural pressure, exchange of O2 & CO2. Internal/External Respiration.
|
|
|
Pulmonary Edema
|
The accumulation of fluid in the extra vascular spaces or alveoli of the lungs.
|
|
|
Pneumothorax
|
Abnormal accumulation of air between the parietal and visceral pleura causing the affected lung collapse.
|
|
|
Pneumonia
|
An acute infection of the lung that impairs the exchange of gasses.
|
|
|
COPD
|
Chronic Obstructive Pulmonary Disease; A chronic airway obstruction that occurs secondary to emphysema, asthma, chronic bronchitis and usually caused by a combination of disorders.
|
|
|
Emphysema
|
Often occurs in conjunction with COPD; An abnormal, irreversable enlargement of the alveoli due to the destruction of the alveolar walls, resulting in decreased elastic recoil of the alveoli
