Respiratory System Flashcards
The respiratory system contributes to _________ by providing for the exchange of gases—oxygen and carbon dioxide—between the atmospheric air, blood, and tissue cells. It also helps adjust the pH of body fluids
Homeostasis
Your body’s cells continually use _______ for the metabolic reactions that generate ATP from the breakdown of nutrient molecules.
Oxygen (O2)
Includes the nose, pharynx (throat), larynx (voice box), trachea (windpipe), bronchi, and lungs, which provides for gas exchange, the intake of O2, and the removal of CO2.
Respiratory System
The respiratory System helps regulate?
blood pH
what receptor for the sense of _____ contained in the respiratory system
Smell Receptors
The branch of medicine that deals with the diagnosis and treatment of diseases of the ears, nose, and throat (ENT) are called
otorhinolaryngology
The entire process of gas exchange in the body
Respiration
Three steps of Respiration
- Pulmonary ventilation
- External respiration
- lungs
- pulmonary capillaries
Internal respiration - systemic capillaries
- tissues
- organs
consists of a series of interconnecting cavities and tubes both outside and within the lungs.
Conducting Zone
the air that we inhale from the atmosphere just passes through from the conducting portion; there is no exchange of gases
Conducting Zone
end of conducting zone
Terminal Bronchioles
Start of conducting zone
Nose
Function of the conducting zone?
- filter
- warm,
- moisten air and conduct it into the lungs
consists of tissues within the lungs where gas exchange occurs between air and blood.
respiratory zone
Beginning of the respiratory zone
respiratory bronchioles
End of the respiratory zone
Alveoli (line the wall of alveolar sacs) - From google
Alveoli - from book
What are the parts of the respiratory zone?

where does the olfactory located
Roof of the Nasal cavity
Parts of Upper Respiratory zone
The upper respiratory system includes the:
1. nose
2. nasal cavity
3. pharynx
4. associated structures
the only external part of the respiratory system
Nose
is a specialized organ at the entrance to the respiratory system and has a visible external portion and an internal portion.
Nose
The external portion of the nose is made of?.
cartilage, skin and is lined with mucous membranes
the nose is adapted for?
WARMING (due to blood vessels), moistening, and filtering air; olfaction; and serves as a resonating chamber.
How nose contributes to noise production
as a resonating chamber
the bleeding from always picking your nose is called?
Epistaxis
It is a funnel-shaped tube about 13 cm (5 in.) that starts at the internal nares and extends partway down the neck.
Pharynx (throat)
The pharynx functions as a _______ for air and food,
Passageway
What organ houses the tonsils
Pharynx (pharyngeal tonsils)
What are the divisions of pharynx
nasopharynx, oropharynx, and laryngopharynx
The nasopharynx functions in?
Respiration
The oropharynx and laryngopharynx function both in?
Respiration and Digestion
The _____ prevents the food from going to the nasopharynx.
The uvula
short passageways that connect the (laryngo)pharynx and the trachea.
Larynx (voice box)
The larynx contains these singles:
- thyroid cartilage (Adam’s apple)
- the epiglottis
- the cricoid cartilage
The larynx contains these pairs: :
- arytenoid cartilage
- False vocal cords
- True vocal cords.
