What is the Function Of the Respiratory System?
|
Exchange of oxygen and carbon dioxide
|
|
|
What is the function of the Respiratory System?
|
exchange of oxygen and carbon dioxide
|
|
|
What is the function of the nasal cavity?
|
- entrance for air
-lined with cilia and mucus to filter and warm air |
|
|
What is the function of the Oral Cavity?
|
entrance for air
|
|
|
What is the function of the Larynx?
|
contains the voice box
|
|
|
What is the function of the Lung?
|
- sponge like organs
- helps move oxygen and carbon dioxide into and out of your body |
|
|
What is the function of the Diaphragm?
|
The diaphragm is a dome-shaped muscle at the bottom of the chest cavity
- helps control breathing |
|
|
What is the function of the Pharynx?
|
shared area with digestive system
(throat) |
|
|
What is the function of the Trachea?
|
- windpipe
- cartilage rings keep trachea open - lined with cilia and mucus to filter and warm air |
|
|
What is the function of the Left and Right Bronchus?
|
- trachea divides into two branches or bronchi - one to each lung
- bronchi branch further into smaller branches in the lung |
|
|
What is the function of the Alveoli?
|
-small grape like sacs at the end of bronchioles
- site of gas exchange (oxygen and carbon dioxide) -greater surface area |
|
|
What is the function of the Rib Cage?
|
- bones that form the walls of the chest cavity
- protect the lungs and other oragans |
|
|
What is ventilation?
|
Ventilation is breathing
- movement of air into and out of the lungs |
|
|
What muscles do you use when you inhale?
|
diaphragm and rib muscles contract = inhale
|
|
|
What muscles do you use when you exhale?
|
diaphragm and rib muscles relax = exhale
|
|
|
What is respiration?
|
- gas exchange of oxygen and carbon dioxide
- capillaries (blood vessels) surround alveolar sacs - gases diffuse across and enter or exit bloodstream |
|
|
What is in the respiratory system?
|
nasal cavity, oral cavity, pharynx, larynx, trachea, lung, right bronchus, left bronchus, bronchioles, alveoli, diaphragm, and the rib cage
|
|
|
What is the respiratory system responsible for?
|
it is responsible for absorbing oxygen from the air and removing carbon dioxide from the blood.
|
|
|
How does the respiratory system depend on diffusion?
|
oxygen from the air diffuses through cell membranes into the bloodstream. The blood stream then distributes the oxygen to all the cells in the body
|
|
|
what is breathing?
|
breathing is the regular movement of air into and out of the lungs
|
|
|
what is respiration?
|
the process by which animals take in oxygen and release carbon dioxide
