What 3 things are the organs of the respiratory system responsible for?
- Bringing fresh air into the lungs
- Exchanging oxygen for carbon dioxide
- Exchanging stale air
The organs of the respiratory system are?
Nasal cavity, pharynx, larynx, trachea, bronchial tubes, lungs
What 2 systems work together on gas exchange?
Respiratory and cardiovascular
Interruption of respiration can cause?
Brain damage or death
What 3 parts are respiration divided into?
Ventilation, external respiration, and internal respiration
The flow of air between the outside environment and the lungs in two stages
Ventilation
The flow of air into the lungs, bringing fresh oxygen
Inhalation
The flow of air out of the lungs, removing carbon dioxide
Exhalation
The exchange of oxygen and carbon dioxide in the lungs
External respiration
What gas leaves air sacs and enters the bloodstream?
Oxygen
What gas leaves the bloodstream and enters air sacs?
Carbon dioxide
The exchange of O2 and carbon dioxide at the cellular level
Internal respiration
This is needed for cell metabolism and it leaves the bloodstream and is delivered to the tissues
Oxygen
This is a waste product and it leaves the tissues and enters bloodstream for disposal by the lungs
Carbon dioxide
Air enters the nasal cavity at the?
Nares
The nasal cavity is divided by the?
Nasal septum
The palate separates the nasal cavity from the?
Mouth
What lines the nasal cavity?
Mucous membrane
This secretes mucus which cleans air by trapping particles
Mucous membrane
This membrane is moist and helps moisturize the air
Mucous membrane
This is located in the membrane and warms the air as it passes through
Capillaries
This lines the nasal openings and filters the air
Cilia
This aids in sound production and voice resonance
Paranasal sinuses
The pharynx has both _____ and _____ functions
Respiratory and digestive
The pharynx is __ inches long and is divided into the nasopharynx, oropharynx, and laryngopharynx
5 inches
This is located in the pharynx and capture pathogens
Tonsils
The opening of the eustachian tube is in the?
Nasopharynx
This is a muscle structure between the pharynx and the trachea
Larynx
The larynx contains folds of tissue known as the?
Vocal cords
This is an opening between the folds that make sound by vibrating as air passes through it
The glottis
The epiglottis prevents ____ and ______ from being inhaled into the lungs
Food and liquid
The epiglottis covers the larynx and trachea during?
Swallowing
The larynx is made of _____ ______ which is held in place with ligaments and muscles
Cartilaginous plates
This is a tube composed of smooth muscle and cartilage rings
Trachea
The trachea carries air from the larynx to the main?
Bronchi
This is lined with mucous membrane and cilia which aids in cleansing, warming, and moisturizing air as it travels to the lungs
Trachea
The distal end of the trachea is divided into?
Left and right main bronchi
Each bronchus enters a ____ and continues branching
Lung
What are the narrowest branches are?
Bronchioles
What do bronchioles terminate in?
Alveoli
Pulmonary capillaries encase ______ and is the site of gas exchange
Alveoli
