chapter 15 respiratory test

the pharynx, larynx and bronchi are in what portion of the respiratory tract?

conducting

blank is a serve, prolonged asthma attack that cannot be broken by repeated doses of bronchodilators?

status asthmaticus

blank molecules are the most abundant gas molecule in the air we breathe

nitrogen???? double check

the blank is the amount of air that remains in the lungs even after a maximal exhalation?

residual volume

the amount of air that can be taken in over and above the resting tidal volume is the

inspiratory reserve volume

the diffusion of gases between the blood and alveolar air across the respiratory membrane is

external respiration

the pressure contributed by a single gas is the blank pressure of that gas

partial

the blank separate(s) the oral and nasal cavities

hard palate

what is a basic function of the respiratory system?

-to produce sound

-to provide a large area for gas exchange

-to provide olfactory sensation

the division of the trachea into the right and left primary bronchi occurs at the

carina

what is treated by pleural decompression?

tension pneumothorax

chnages in the volume of the thoracic cavity results from movements of the diaphragm and the

rib cage

what structure provides posterior support to the larynx

cricoid cartilage

blank is the process that involves gas exchange and gas transport

respiration

blank is low tissue oxygen levels

hypoxia

movement of air into and out of the alveoli is called

pulmonary ventilation

blockage of pulmonary blood vessels that restricts blood flow to the lungs is called»>

pulmonary embolism or pe

blank results from an increase in numbers of goblet cells in the respiratory system

chronic bronchitis

the trachea begins at the level of the blank cervical vertebra and ends at the level of the blank thoracic vertebra

sixth, fitfh

enlargement of the lower airways due to sympathetic activation is called

bronchodilation

the base of the lung can be found where

on the top of the diaphragm

the medial margin of the left lung indented where

cardiac notch

rising PCO2 levels cause the blank of smooth muscles in the walls of the arterioles

relaxation

what is the physical movement of air into and out of the lungs called

respiration

after entering the bloodstream, a carbon dioxide molecule may

be converted to carbonic acid

what levels are responsible for regulating activity under normal condition

oxygen, carbonic acid and carbon dioxide

the blank is the maximum amount of air that can be moved into and out of the lungs in a single respiration

vital capacity

what membrane is made up of respiratory epithelium and the lamina propria?

respiratory mucosa, tracheal lining and lacrimal sinuses

the best defense against the spread of upper respiratory infection is to

practice common hygiene

a segment of lung tissue that is bounded by connective tissue partition and supplied by a single bronchiole is called

a pulmonary lobule

the blank of the lungs is an indication of their resilience and ability to expand

compliance

order for air passing through the respiratory system

nasal cavity/ mouth

pharynx

larynx

trachea

brochi

bronchioles

alevoli

genetic disease involves mucous cells in the respiratory mucosa producing dense, viscous mucus that cannot be transported by respiratory cilia

cystic fibrosis

blank are common chambers connected to multiple individual alveoli

alveolar sacs

patients who require prolonged ventilation assistance are placed on what device

mechanical ventilator

only about 1.5 percent of the oxygen content of arterial blood consists of oxygen molecules in solution. the rest of the oxygen molecules are bound to blank molecules

hemoglobin

the blank is the amount of air moved into or out of the lungs during a single respiratory cycle.

tidal volume

the maxillary, nasal, frontal, ethmoid and sphenoid bones form the lateral and superior walls of the

sinuses

blank is one of the worlds most common and serious infectious diseases

respiratory syncytial virus or RVS

forced breathing involves the accessory muscles during inhalation and the blank muscles and abdominal muscles during exhalation

internal intercostal

high levels of co2 in the blood is

hypercapnia

types of obstructive lung disease

chronic bronchitis. emphysema and asthma

true or false: the inflation reflex prevents the lungs from over expanding during forced breathing

true

when food touches the blank, it can trigger the coughing reflex

vocal cords

example of secrete surfactant

septal cells

what breaks the fluid bond between the pleurae

pneumothorax

subdivision of the pharynx extends between the level of the hyoid bone and the entrance of the esophagus

laryngopharynx

an blank process requires oxygen

aerobic

when PCO2 declines, bronchioles

constrict

what anatomical structure consists of nine cartilages stabilized by ligaments and skeletal muscle

larynx aka the voice box
