Ch. 7 Terms Flashcards
Allogenic
Genetically different but obtained from the same species.
Alveoli (air sacs)
The primary units for the exchange of oxygen and carbon dioxide in the lungs.
Apheresis
Filtering of blood to remove stem cells.
Autologous
Obtained from the patient.
Bone Marrow
The flexible tissue found in the center of many bones, primarily in cancellous tissue of the ribs, vertebrae, sternum, and bones of the pelvis.
Bronchi
Bottom portion of the trachea that splits into airways to the right and left lung; the right is shorter and wider than the left.
Carina
The ridge that separates the opening of the right and left bronchi.
Chronic Obstructive Pulmonary Disease (COPD)
A progressive disease that causes coughing, wheezing, shortness of breath, and difficulty breathing. The primary cause is smoking.
Cilia
Microscopic filaments bathed in nasal mucus that cover the surface of the tissue in the nose.
Concha Bullosa
Enlargement of the nasal turbinate.
Croup
A common, high-pitched, barking cough found in infants and children with nasal-type symptoms.
Diaphragm
Muscle separating the abdominal cavity from the thoracic cavity; primary muscle in respiration contracting (inflating) and relaxing (deflating) the lungs.
Dacryocystorhinostomy
Surgical procedure that restores the flow of tears into the nose from the lacrimal sac when the nasolacrimal duct does not function.
Decortication
Separating the pleura adhering to lungs to assist with expansion of the lungs.
Direct Endoscopy
Use of an endoscope to look directly at the larynx.
Empyema
Collection of pus between the lung and the lining of the lung (pleural space).
En bloc
In total or in full; as a single piece.
Epiglottis
A lid or flap that covers the larynx to protect the trachea from inhaled food or liquid.
Glottis
Vocal cords separated by a triangular opening, through which air flows. The glottis narrows, controlling the flow of air, which causes the vocal cords to vibrate and create sound.
Hemic
Pertaining to blood. SYN - hematic.
Hyoid Bone
A horseshoe-shaped bone in the anterior midline of the neck. It is not part of the trachea and does not articulate with any other bone. It provides attachment to the muscles of the floor of the mouth and the tongue above, the larynx below, and the epiglottis and pharynx behind.
Indirect Endoscopy
Use of mirrors with a rigid laryngoscope to view the larynx.
Instill
To introduce gradually
Larynx (Voice Box)
Connects the nasopharynx to the trachea, covered by the epiglottis during swallowing to prevent aspiration.
Lungs
The right lung has three lobes and the left lung has two lobes.
Mediastinum
The portion of the thoracic cavity between the lungs containing the heart, aorta, esophagus, trachea, and thymus gland, as well as blood vessels and nerves.
Pleura
A serous membrane that folds back onto itself to form a two-layered structure.
Pleural Cavity
The space between the two pleural layers.
Pneumonectomy
Removal of a lung.
Pneumonolysis
A procedure that separates the chest wall from the lungs to prevent collapse.
Pneumothorax
Collapse of the lung.
Pulmonary Function Tests
Tests to diagnose breathing problems.
Trachea (Windpipe)
Cartilaginous structure that carries air from the nasopharynx to the lungs via the bronchi.
Turbinates
Superior, middle, and inferior bony structures found in each right and left nasal cavity to assist with air movement.
Septum
Bony structure that separates the left nasal cavity from the right nasal cavity.
Splenoportography
A method of using X-ray imaging to view the portal system via the spleen.
Video-Assisted Thoracoscopic Surgery (VATS)
Use of endoscope and the video to perform diagnostic and surgical procedures on the thoracic cavity.
Vital Capacity (VC)
The maximum volume of air a person can exhale after maximum inhalation. The measure is used in diagnostic pulmonary testing.
