Respiratory System Flashcards
The exchange of gases between the atmosphere, blood and body cells called —————-
Respiration
There three components of Respiration are ;
1.———2.———-3.————-
- atmosphere 2. blood 3. body cells
Pulmonary Ventilation is made of 2 components :
- Inhalation
2. Exhalation
The flow of the air into the lungs called —————aka———-
Inhalation aka inspiration
The flow of the air out of the lungs called —————aka———-
Exhalation aka expiration
The exchange of gases across the respiratory membrane called ———-
Pulmonary respiration
exchange of gases between the blood and tissue cells called————
tissue respiration
The metabolic reactions that consume oxygen and release carbon dioxide in the production of ATP called———-
cellular respiration and it is part of the aerobic respiration
There 6 structures/divisions to the Respiratory system;
- nose
- pharynx
- larynx
- trachea
- bronchi
- lungs
The upper Respirator system is made with of;
- nose
2. pharynx
The lower respiratory system is made of :
- larnyx
- trachea
- Bronchi
- lungs
There are 2 conducting zones in the respiratory system:
- conducting Zone (1.nose, 2.pharynx, 3.larynx, 4.trachea,
5. bronchi, 6. bronchioles, 7. terminal
bronchioles) - respiratory zone (1. respiratory bronchioles, 2.alveolar ducts,
3.alveolar sacs, 4. alveoli)
The function of the conducting zone is to :
1.
2.
3.
- to filter, warm, and moisten the air and to conduct it in the the
lungs. - to receive olfactory (smell) stimuli (goes directly to olfactory cortex
not to the thalamus), also the smell goes to other part of the brain
memory smell such as hippocampus - sound generation for speech (larnyx; voice box)
The branching of the Bronchial Tress starts from :
1. Trachea then
- Trachea
- Main bronchi
- lobar bronchi
- segmental bronchi
- bronchioles
- terminal bronchioles
The function of respiratory zone is for ;
gas exchange
Alveolar sac is made of individual———that is very highly ———
Alveoli highly vascularized (O2 in, Co2 out)
It is the first line of defense when inhaling , houses olfactory receptors, rich blood supplies, and has a sticky mucous traps particulate called ——-
the nose
———has ciliated cells move the mucous to the throat (pharynx)where it is swallowed and digeste
the nose
A funnel-shaped tube just behind the nasal cavity and above the larynx, functions as a passageway for air and food, as a reasoning chamber for sounds, and as a housing for tonsils called
the ——–aka——-
pharnyx aka throat
At the inferior end called ——-, it opens into the esophagus and larynx called ——–aka——-
Laryngopharynx,
called the pharnyx aka throat
It is the voice production, routes air and food into their proper channels (trachea vs esophagus) called
Larnyx
Inferior to where the pharnyx splits into the trachea and the esophagus called ————
the larnyx
———protects the top of the larnyx
epiglottis
anterior to the esophagus, fairly rigid , C-shaped rigid of hyaline cartilage that reinforce and supports its shape called——-
Trachea
lined with mucous membrane to filter particulate called ————
the trachea
Cilia sweep particulate out of the trachea to the throat for ——-or ———-
expectoration (elevator of structure)
digestion
At the 5th thoracic vertebrae (T5) divides into the right and left primary ———which travel to the right and left ——–
bronchi
lungs
An internal ridge where the trachea divides - it is one of the most sensitive areas of the trachea and larynx for triggering a ————– called ———–
cough reflex
carina (covered with mucous membrane)
2 organs separated by the heart and other structures in the mediastinum called ——–
the lungs
the region in the thoracic cavity between the lungs - it extends from the sternum to the vertebrae and from the 1st rib to the clavicle called
mediastinum
