Respiratory Structure-Function Relationships- Ward/CJ- 1/7/13
Question | Answer |
---|---|
Diffusion happens fastest through membranes that have | Large surface areas and thin barriers |
Surface area is how many times greater with alveoli? | 1000 |
The respiratory area of the lungs includes the | Respiratory bronchiole, alveolar duct, alveolar sac |
The area of the lungs that is not active in gas exchange is known as the | Conducting zone |
Pathway of diffusion from Alveoli to plamsa | Alveoli, Surfactant, alveolar epithelium, interstitium, capillary endothelium, plasma |
Structures that are in direct contact with the lungs | Aorta, Heart, Diaphragm, Vena Cava |
Explain the flow of the lymphatics in the lung | Pulmonary nodes- Bronchopulmonary hilar nodes- Superior/Inferior tracheobronchial nodes- Paratracheal nodes- Bronchomediastinal trunk (or Inferior deep cervical nodes-Supraclavicular-Jugular lymph trunk)-Subclavian |
Which side of subclavian gets the majority of lymph drainage? | Right |
