Respiratory
Path of air as it travels from the outside environment to the alveoli.
1)Nostril 2) Nasal Cavity3) Pharynx: (Nasopharynx, Oropharynx, and Laryngopharynx)4) Larynx 5) Trachea 6) Primary Bronchii 7) Secondary Bronchii 8)Tertiary Bronchii 9) Bronchioles 10) Terminal Bronchioles 11) Respiratory Bronchioles 12) Alveoli
Which muscles are used in forced exhalation?
Abdominal wall muscles primarily oblique and transverses muscl
At the end of the bronchial tree tips, how are the alveolar ducts and sacs arranged to lead air into alveoli?
Alveolar ducts lead into terminal clusters of alveoli called alveolars sacs and then finally alveoli. Gas exchange occurs in the alveoli.
What type of tissue is larynx mostly made up of
Ciliated Psuedostratified epithelial tissue
What is the true and false vocal cords?
False vocal cords are not involved in voice production, true are responsible for speech.
What type of tissue makes up the tracheal rings?
Hyaline
What are the names of the three regions of the pharynx.?
Nasopharynx: A passageway for Oropharynx: A passage for food and air -Laryngopharynx: A passage for food and air
What are the names of the three regions of the pharynx.?
Nasopharynx: A passageway for air Oropharynx: A passage for food and air Laryngopharynx: A passage for food and air
What organs/structures belong to the upper respiratory tract?
Nostril, Mouth, Nasal Cavity, Pharynx
What type of tissue makes up the lining of the Trachea?
Pseudostratified columnar epithelial tissue
Which muscles are used in forced inhalation?
Scalenes, sternocleidomastoid muscles of the neck, pectorals minor of the chest, raise ribs
What two types of cells make up an alveoli?
Simple squamous epithelial cells & Cuboidal epithelial cells
How do the vocal cords vibrate for varying pitches of sounds?
The vocal folds and medial opening between them through which air passes are called the glottis.
What organs/structures belong to the lower respiratory tract?
Trachea, Lungs, Bronchus
What is the bronchial Tree?
a branching system of air tubes in each lung
where is the pharynx?
back of throat
where is the larynx?
between pharynx and trachea
What is internal respiration?
exchange of gases between blood and body cells
What are turbinates?
found inside the walls of the nasal cavity. They warm, humidify, and filter the air you breathe.
What is external respiration?
gas exchange between lungs and blood
What is ventilation?
movement of air in and out of the lungs
What are tracheal rings and what is their purpose?
purpose is to reinforce the trachea and keep the trachea patent. (From collapsing)
What type of tissue are alveoli made up of?
simple squamous epithelium
What surrounds the bronchi and bronchioles that make them stiff?
surrounded by Smooth muscle that increases as the passageways become smaller that makes them stiff.
Which muscles are used in regular inhalation?
the diaphragm contracts and ribs are elevated and sternum flares external intercostal muscles contract
