respiratory center |
|
- Identify the organs forming the respiratory passageway(s) in descending
order until the alveoli are reached. Distinguish between conduction, regulatory
and respiratory zone (exchange) structures. Describe their histology.
- Describe the change in histology of the respiratory tree and give each
tissue function.
- Discuss the interplay between the lungs and pleural coverings in terms
of ventilation. Explain the functional importance of the partial vacuum that
exists in the intrapleural space.Explain the relative roles of the respiratory
muscles and lung elasticity in affecting volume changes that cause air flow
into and out of the lungs.
- Compare and contrast mechanisms of regulation of ventilation. Demonstrate
understanding of nervous control of respiratory rate by constructing a reflex
arc. Use
this neural negative feedback loop template.
- Describe the mechanisms for oxygen transport, and explain how oxygen loading
and unloading is affected by changes in temperature, pH, BPG, and PCO2. Explain
the role of Bohr effect in oxygen transport.
- Describe mechanisms of carbon dioxide transport in the blood.
- Explain the role the respiratory sytem has in blood pH balance.
