|
List the main functions of the respiratory system |
Ventilation, gas exchange, gas transport in blood and control of ventilation |
|
|
Name the organs that separate the nasal cavity from the oral cavity |
The hard and soft palates |
|
|
What are conchae or nasal turbinates |
Small bones that splits the nasal cavity into 3, dorsal, middle and ventral nasal
|
|
|
What structures help humidifying and warming up the inspired air in nasal passages |
Nasal conchae |
|
|
Name the cranial nerve that carries the impulses of small to brain |
Olfactory Nerve |
|
|
What is a sinus |
cavity within a bone or other tissue, connecting with the nasal cavities |
|
|
Name the sinus that may get infected when dehorning an adult cow |
frontal sinus |
|
|
Organ that serves as a common passage for both food and air |
Pharynx |
|
|
Structures that open into the pharynx |
two caudal nares, two auditory tubes, oral cavity, the larynx and esophagus |
|
|
all the cartilages of the larynx |
Thyroid, Arytenoid(2), cricoid and epiglottis |
|
|
Cartilage that prevents food from entering into the trachea during swallowing |
Epiglottis |
|
|
Cartilage that is ring shaped and helps in maintaining shape of larynx |
Critoid |
|
|
Why is the cartilage rings of trachea are incomplete dorsally |
prevents collapsing during respiration |
|
|
List of all subdivisions of trachea in order from largest to smallest |
Bronchi Primary, Bronchi Secondary, Bronchioles, Alveolar ducts, Alveoli |
|
|
Pneumothorax |
air trapped in the thoracic cavity |
|
|
Atelectasis |
incomplete expansion of lungs |
|
|
Membrane that covers the lung |
Pleura |
|
|
difference between external and internal respiration |
External is gaseous in lungs, internal is gas exchange in tissue |
|
|
Two major muscles that help in respiration |
diaphragm and intercostal muscles |
|
|
changes in the thoracic cavity results in inspiration |
diaphragm pushes the abdominal contents down |
|
|
what happens during expiration |
diaphragm relaxes the lungs |
|
|
Apea |
no breathing |
|
|
Dyspnea |
painful breathing |
|
|
Hyperpnea |
increase of rate in breathing |
|
|
Polypnea |
rapid and shallow breathing |
|
|
Tidal volume |
amount of air inspired and expired during respiration |
|
|
Residual volume |
the amount of air remaining in the lungs |
|
|
Anatomical dead space |
volume of air from nose to mouth to alveoli |
|
|
Physiological dead space |
includes anatomical and dead alveoli |
|
|
Upper Respiratory |
nostrils, nasal cavity, pharynx, larynx, and trachea |
|
|
Pulmonary Emphysema |
due to enlargement of the alveoli of the lungs |
|
|
Passive Movement |
decrease in volume |
