What are the four phases of respiration?
|
1) Pulmonary ventilation
2) External respiration 3) Trasportation of respiratory gases 4) Internal respiration |
|
|
Define pulmonary respiration
|
air is pulled into lungs
|
|
|
Define external respiration
|
gas exchange in the lungs
|
|
|
Define internal respiration
|
gas exchange in the tissues
|
|
|
In what region of the tissues does internal respiration occur?
|
in the capillary region
|
|
|
What is the purpose of the nose in respiration?
|
warms and moistens the air
|
|
|
Pharynx
|
common pathway for food and air
|
|
|
Larynx
|
directs food and air (epiglottis)
|
|
|
Trachea
|
carries air into lungs
|
|
|
What is the purpose of the broncial tree in respiration?
|
brings gas into lung lobes
|
|
|
The trachea branches into the ________ and the _________ _______.
|
branches into the bronchus and bronchial tree
|
|
|
Purpose of lungs
|
gaseous exchange
|
|
|
Which side of the lungs has an extra lobe?
|
right lung
|
|
|
Name the two main lung lobes in the dog
|
cranial and caudal
|
|
|
Name two functions of the pleural cavity.
|
1) decreases friction
2) provides vacuum to keep lungs inflated |
|
|
The plerual cavity is bordered by
|
a visceral sac surrounding the lungs, filled by fluid
|
|
|
Name the 7 anatomical features of the respiratory system
|
1) Nose
2) Pharynx 3) Larynx 4) Trachea 5) Bronchial tree 6) Lungs 7) Pleural cavity |
|
|
Name the 5 anatomical features of the lungs (path that air takes).
|
1) Trachea
2) Bronchus 3) Sm bronchi 4) Bronchioles 5) Alveolar Sacs |
|
|
Describe the two phases of pulmonary ventilations
|
Inspiration- diaphragm contracts, chest cavity is bigger, pressure drops in lungs, air enters
Expiration- diaphragm relaxes, increases pressure, chest cavity returned to normal size |
|
|
Name the three aspects of breathing mechanics.
|
A) Pulmonary ventilations
B) Pressure relationship in the thoractic cavity C) Control of respiration |
|
|
Name the two parts of the brain that control respiration.
|
1) Medullary respiration center (Medulla oblongata)
2) Pons respiration center |
|
|
What does the Medullary respiration center control
|
controls basic breathing rythm
|
|
|
What does the Pons respiration center control?
|
alters breathing rate and pattern depending on what the body needs
|
|
|
Name 5 benefits of massage on the respiratory system
|
1) Reduces respiration rate
2) Strengthens respiratory muscles 3) Decreases asthma attacks 4) Increases fluid discharge from the lungs 5) Improves pulmonary function |
