Session 9_Pulmonary Ventilation and Circulation Flashcards
What is the highest recorded “sneeze speed”?
99 miles per hour
What is the surface area of the lungs roughly the same size as?
a tennis court
How much water do we lose everyday through breathing?
1/2 liter
How many lobes does the right lung have?
3
How many lobes does the left lung have?
2
The lungs occupy all thoracic cavity except:
mediastinum
3rd cervical vertebra, to 6th =
location (posteriorly) larynx
Larynx separates:
separation of food of air
The right lung has 2 fissures =
horizontal and oblique fissures
The left lung has 1 fissure =
oblique fissure
The left lobe also has the little extension of:
lingula
What is the potential pathology of the pleurisy/ pleuritis?
inflammation of pleural cavity –> rough –> friction rub
What are some potential causes of pleurisy?
chest trauma, cancer, pulmonary embolis, autoimmune disease (lupis), rheumatoid arthritis.
What part of the O2 transport system would be involved in pleurisy?
????
inspiration
What type of connective tissue is the lung tissue?
primarily elastic
What does the elasticity of healthy lungs help reduce?
Reduce the work of breathing
The bronchopulmonary segments of the lungs are separated by:
connective tissue septa
The bronchopulmonary segments of the lungs are served by own:
lung and artery
The bronchopulmonary segments received air from:
individual bronchus
Cancer caught early in bronchopulmonary segments, can be removed without:
affecting other parts –> people can survive
What are three regions of the Right Upper bronchopulmonary segments?
- apical
- anterior
- posterior
What are the 2 regions of the Right middle bronchopulmonary segments?
- lateral
2. medial
What are the 5 regions of the Right lower (base) bronchopulmonary segments?
- anterior
- superior
- lateral
- posterior
- medial
What are the 4 regions of the Left Upper bronchopulmonary segments
- apical posterior
- anterior
- superior (lingula)
- inferior (lingula)
