Shortness of Breath
Pre-Module Knowledge Check
The upper respiratory system consists of:
|
the nose and mouth
| |
|
the nose, nasal cavity and pharanyx
| |
|
the oral cavity, epiglottis and trachea
| |
|
The nasal cavity, trachea and pharanyx.
|
The lower respiratory tract comprises:
|
the throat and lungs
| |
|
the pharanynx, trachea and alveoli
| |
|
the larynx, trachea, bronchi , bronchioles and alveoli
| |
|
the soft palate, trachea, bronchi , bronchioles and alveoli
|
The trachea can best be described as:
|
a "pipe" which connects the lungs to the mouth
| |
|
a pipe made up of several "C" shaped rings which allow for expansion and contraction during the breathing process
| |
|
a smooth cartilagenous tube which stretches and contracts during the breathing process
| |
|
a series of "O" shaped cartilagenous rings expand and contract during the breathing process
|
What happens at the alveoli level during the breathing process?
|
Oxygen from the blood crosses the alveloar membrane into the lungs while carbon monoxide crosses into the blood, attaching to the red blood cells.
| |
|
Oxygen crosses the alveloar membrane into the lungs while carbon dioxide crosses into the blood, attaching itself to red blood cells.
| |
|
Carbon dioxide crosses the alveloar membrane into the lungs while oxygen crosses into the blood.
|
A person's respiratory rate is controlled by:
|
the CNS (central nervous system) ... when the carbon-dioxide level in the blood rises, the respiratory rate goes up.
| |
|
the CNS (central nervous system) ... when the oxygen concentration in the blood rises above what is needed for the current level of activity, the respiratory rate goes down.
| |
|
sensor cells in the walls of the alveoli - when the carbon-dioxide level in the blood rises, the respiratory rate goes up.
