Respiratory System Flashcards
Testosterone affects the development of this structure in men to becomes the adam’s apple.
Hyoid cartilage
This heart/leaf shaped cartilage helps to top food back into the esophagus.
epiglottis
These paired cartilage pieces help to support the mucus membrane in the throat.
Cuneiform cartilages
These cartilage pieces of the throat can pivot and slide. The vocal cords attach to here. These cartilages are also paired.
Arytenoid cartilage
These paired cartilages sit atop the arytenoid cartilages.
corniculate cartialges.
This unpaired piece of cartilage looks like a signate right (like a class ring) and is the only cartilage in the throat that makes a complete ring.
Cricoid cartilage.
This structure is comprised of ~16 c shaped cartilages which are open on the posterior side.
Trachea
True or false. The right primary bronchus is wider and more vertical than the left bronchus.
True.
This highly innervated structure of the bronchi at the division between the left and right primary bronchus sets up a reflex to cough a lot.
Carina
These structures in the pathway of air are lined with pseudostratified epithelium. and divide at the sternal angle.
Primary bronchi
These structures of the pathway of air has a branch which supply air to each lobe of the lung. 3 on the right and 2 on the left.
Secondary (lobar) Bronchi
These bronchi supply each of the bronchopulmonary segment of the lung, 10 on the right and 10 on the left.
Tertiary (segmental) Bronchi
In these portions of the bronchi, the cartilage is no longer present and consists of smooth muscle which can shut during an asthmatic attack.
Bronchioles.
Terminal Bronchioles are lined with this type of tissue.
Simple cuboidal epothelium.
Respritory bronchiols are lined with this type of tissue.
simple squamous epithelium
This structure describes where 2 or more aveoli share a common opening.
Aveolar sacs
Name the structures in the pathway of air.
Trachea, Primary bronchi, secondary bronchi, tertiary bronchi, bronchioles, Terminal bronchioles, respritory bronchioles.aveolar ducts, aveolar sacs, aveoli.
Each lung is invested and enclosed in a serous pleural sak that consists of two membranes. What are they?
Visceral Pleural membrane and parietal pleural membrane.
This pleueal membrane of the lung adheres to the surface of the lungs and penetrates the fissues.
Visceral pleural membrane
This pleural membrane of the lung adheres to the thoracic wall, mediastinum and diaphragm.
Parietal pleural membrane
Describe the pleural membrane of the lungs.
It is the potential space between the pleural membrane which contains serous pleural fluid.
during the treatment of lung cancer, the surgeon can perform one of three operations, what are they?
Pneumonectomy, lobectomy, or segmentectomy.
What is a pneumonectomy?
It is the removal of an entire lung.
What is a lobectomy?
It is the removal of a lobe of a lung.
