Which systems work together to supply the body with oxygen and dispose of carbon dioxide
Cardiovascular & Respiratory
The organs of the respiratory system include...
-Smaller branches (bronchioles)
*The respiratory conducting passageways are responsible for...
-Warm incoming air
-Allowing air to reach the lungs
What of the nasal mucosa create a gentle current that moves contaminated mucus toward the throat/pharynx?
WHat happens to the contaminated mucus if the ciliated cells in the nasal mucosa are functioning properly?
Moves mucus towards the pharynx --> then swallow
What happens to the contaminated mucus if the ciliated cells in the nasal mucosa are not functioning properly (e.g. if it is very cold)
Cilia becomes sluggish=runny nose
*What is the function of the sinuses?
-lighten the skull
-act as resonance chambers for speech
---- in the trachea propel contaminated mucus toward the ---- to be ----or spat out
Cilia, Pharynx/throat, swallowed
What protects the superior opening of the larynx therefore restricting anything but air to enter the trachea?
Formed by the division of the trachea and lead to the right and left lungs respectfully
The right and left Primary Bronchi
THe fluid secreted by the membranes allows the
Lungs to glide over the thorax wall during breathing.
The respiratory zone includes the following structures:
*List the 4 distinct events that occur during respiration
-respiratory gas transport
The amount of air coming into and out of the lungs with each breath during normal breathing
Tidal Volume (TV)
Oxygen is transported in the blood in 2 ways
On red blood cells as oxyhemoglobin
and a small amount dissolved in the plasma
The bluish cast that results from inadequate oxygenation (---) of the tissues is called?
A group of diseases exemplified by chronic bronchitis and emphysema and is major cause of death & disability in the US
Chronic Obstructive Pulmonary Disease (COPD)
*Emphysema causes the following:
-decreased lung elasticity
*Caused by the inhalation of food or other foreign substances into the lungs, thus leading to pneumonia
*Involves using the uvula to close the oral cavity off from the pharynx in order to clear the upper respiratory passages
*Formerly believed to be triggered by low oxygen. It is a deep inspiration that ventilates all the alveoli
*Primarily an emotionally induced mechanism that involves the release of air in a number of short breaths, similar to laughing
