Chapter 28 - The Respiratory System Flashcards
Alveoll
Clusters of air sacs in which the exchange of gasses between air and blood take place located in the lungs.
Bronchi
The two branches of the trachea that enter the lungs.
Bronchioles
A part of the respitory tract that brances from the tertiary bronchi
Dyspnea
Difficult or paininful breathing
Epiglottis
The flap-like structure that closes off the larynx during swallowing
Expiration
The process of breathing out; exhalation
Glottis
The opening between the vocal cords.
Inspiration
The act of breathing in; inhalation
Laryngopharynx
The portion of the pharynx behind the larynx
Larynx
The part of the respiatory tract between the pharynx and the trachea that is responsible for voice production; also known as the voice box
Morbidity
The frequency of the appearance of complications following a surgical procedure or other treatment; a disease state.
Morality
A fatal outcome
Nares
The opening of the nose; also known as nostrils
Nasal Conchae
Structures that extend from the lateral walls of the nasal cavity
Nasopharynx
The portion of the pharynx behind the nasal cavity
Orophanrynx
The portion of the pharynx behind the oral cavity.
Paranasal sinuses
Air-filled pockets within the skull bones that open into the nasal cavity
Pharynx
Structure below the mouth and nasal cavities that is an organ of the respiratory system as well as the digestive system
Pleura
The membranes that surround the lungs
Repository capacity
The amount of air that the lungs can hold, calculated by adding certain respiratory volumes together
Respiratory volume
The different volumes of air that move into and out of the lungs during different breathing intensities. These volumes can be measured to assess the healthiness of the respiratory system
Surfactant
Fatty substance secreted by some alreolar cells that helps maintain the inflation of the alveoli so that they do not collapse in on themselves between inspirations
Thoracocentesis
Medical procedure in which a sterile needle is introduced into the chest to remove fluid and pus
Thoracostomy
The surgical insertion of a chest tube to provide continuous drainage of the thoracic cavity
Thorax/Thoratic
The chest cavity
Trachea
The part of the respiratory tract between the larynx and the bronchial tree that is tubular and made of rings of cartilage and smooth muscle; also called the windpipe
What is the function of the respiratory system?
It is to move air in and out of the lungs, also known as ventilation, respiration, or breathing
What is external respiration?
The exchange of oxygen and carbon dioxide in the lungs.
What is internal respiration?
The exchange of oxygen and carbon dioxide that occurs in the hemoglobin of RBCs.
What are the organs of the Respiratory system?
Nose, Pharynx, Larynx, Trachea, Bronchial tree, and lungs
What is part of the bronchial tree?
- bronchi 2. bronchioles
Nares
The openings of the nose; also known as nostrils
What is the nasal cavity?
The hollow space behind the nose. It is separated by the cartilaginous nasal septum
