Respiration Systems Flashcards
What are three main challenges to aerobic function
Getting oxygen to the alveoli
Getting oxygen from the alveoli into the blood as it travels through pulmonary blood vessels
Delivering sufficient oxygen to meet individual cells’ needs
In Australia in 2015 respiratory disease affected how much of the population?
30%
In Australia in 2015 respiratory disease caused how many deaths in percentage?
14% of deaths, 3% of hospitalisations and 6% of the total burden of disease
Why do we need respiration?
To supply oxygen needed for aerobic energy production
To regulate pH
What are the two respiratory system parts?
Conducting system – involved in gas movement for ventilation
Gas exchange system
Each step in the respiratory system represents a limitation to gas flow. Why is that?
If resistance is increased at any point in the respiratory system, movement of gas through the system will be decreased.

Which of the following statements is CORRECT?

.
Which statement best describes the structure of the larynx?
A. The larynx is made up of 3 cartilages
B. The larynx is made up of 6 cartilages
C. The larynx has 3 paired and 3 unpaired cartilages.

What does the Mucosa of the trachea and Bronchi comprise of?
Ciliated cells
Goblet (mucous producing) cells
Sero-mucous glands in sub mucosa
Which of the following statements is CORRECT?
A. The tracheal rings are incomplete anteriorly.
B. The trachea forms a rigid tube.
C. Because the tracheal cartilages are incomplete posteriorly, food can pass through the oesophagus.
D. The structure of the trachea prevents it from bending.
