Respritory System Flashcards
Nares =
Nasal cavity
Pharynx =
Throat
2 sides of the nares is separated by the
Nasal septum
A feeding tube would be placed where in the nasal cavity
Ventral medial
Larynx connects the pharynx with the
Trachea
Covers the larynx when swallowing
Epiglottis
Trachea is also know as the “ “
Windpipe
Inspiration is the process of
Drawing air into the lungs
Expiration is the process of
Pushing air out of the lungs
What are the secondary functions of the respiratory system
Body temperature regulation, voice production, acid base regulation, sense of smell
What is the primary function of the respiratory system
Swapping O2 and CO2 throughout the cells and lungs
Hyperventilation RR _______ and CO2______= respiratory ________.
High, low= Alkalosis
Hypoventalation RR ______ and CO2 ________= respiratory ________
Low, high, acidosis
What part of the respiratory system creates sounds
Larynx
The upper respiratory tract consists of
All structures outside the lungs
The lower respiratory tract consists of
All structures within the lungs
Nasal passages are called
Turbinates
An animal must have ________ pressure in the lungs to take breaths
Negative
What is Tidal volume
Total volume of air in one breath
Residual volume
The volume of air left after a breath
The volume of air inhaled and exhaled during respiration over a minute
Minute volume
The Diaphragm is considered what type of muscle
Skeletal
Breathing is controlled by an area in the medulla oblongata of the
Brainstem
The ________ control system for breathing is a preset and automatic system
Mechanical
The ___________ control system for breathing only affects breathing patterns only when something is out of balance
Chemical
Chemical receptors that monitor blood are located where
Carotid artery, aorta, brain stem
Inflammation of the sinuses is called ?
Sinusitis
If the carbon dioxide level in blood decreases, the PH usually _______ and respiration _______.
Rises, decreases
What happens from negative thoracic pressure
Blood is pulled into the large veins in the mediastinum and returns to the heart
What structures form the boundaries of the glottis
Arytenoid cartilages and vocal chords
What type of tissue lines the alveolus
Simple squamous
The blood, lymph, nerves, and vessels enter and exit the lungs in this section
Hilus
What bridges the gap between the ends of each cartilage ring in the trachea ?
Smooth muscle
What is the primary chemical control of breathing
Blood carbon dioxide level
What is the name of the nasal passage way in the nose
Meatus
Alveoli are responsible for
External respiration
What is the volume of air inspired and expired during 1 minute
Minute volume
What is the volume of air inspired and expired during one breath
Tidal volume
The volume of air remaining in the lungs after maximum expiration
Residual volume
