Class 3 Vocab

functional units of the lung; the thin-walled chambers surrounded by networks of capillaries that are the site of respiratory exchange of carbon dioxide and oxygen

one of the respiratory passageways into which the segmental bronchi divide

manubriosternal angle, the articulation of the manubrium and body of the sternum, continuous with the second rib

cessation of breathing

slow breathing, <10 breaths per minute, regular rate

the normal breath sound heard over major bronchi, characterized moderate pitch and an equal duration of inspiration and expiration

millions of hairliek cells lining the tracheobronchial tree

(rales) abnormal, discontinuous, adventitious lung sounds heard on inspiration

space between the ribs

difficult, labored breathing

a palpable vibration from the spoken voice felt over the chest wall

increased rate and depth of breathing

rapid, shallow breathing, >24 breaths per min

ability to breathe easily only in an upright position

striking over the chest wall with short, sharp blows of the fingers to determine the size and density of the underlying organ

low-ptiched, musical, snoring, adventitious lung sound caused by airflow obstruction from secretions

the soft, low-pitched, normal breath sounds heard over peripheral lung fields

sword-shaped lower tip of the sternum

high-pitched, musical, squeaking adventitious lung sound

In the anterior chest, the highest point of lung tissue is 3 to 4 cm above the inner third of the clavicles

the highest points of the lungs

acute chest pain that occurs when myocardial demand exceeds its oxygen supply

the left semilunar valve separating the left ventricle and the aorta

tip of the heart pointing down toward the 5th left intercostal space

pulsation created as the left ventricle rotates against the chest wall during systole, normally at the 5th left intercostal space in the midclavicular line (point of maximal, PMI)

cup-shaped endpiece use dfor soft, low-pitched heart sounds

slow heart rate, <50 beats per min in the adult

bulbous enlargement of distal phalanges of fingers and toes that occurs with chronic cyanotic heart and lung conditions

dusky blue mottling of the skin and mucous membranes due to excessive amount of reduced hemoglobin in the blood

flat endpiece of the stethoscope used for hearing relatively high-pitched heart sounds

the heart's filling phase

swelling of legs or dependent body part due to increased interstitial fluid

tradition ausculatory area in the 3rd left intercostal space

occurs with closure of the atrioventricular valves signaling the beginning of systole

imaginary vertical line bisecting the middle of the clavicle in each hemithorax

left AV valve separating the left atria and ventricle

uncomfortbale awareness of rapid or irregular heart rate

area of the chest wall overlying the heart and great vessels

right semilunar valve separating the right venticle and pulmonary artery

occurs with closure of the semilunar valves, aortic and pulmonic, and signals the end of systole

temporary loss of consciousness due to decreased cerebral blood flow (fainting), caused by ventricular asystole, pronounded bradycardia, or ventricular fibrillation

the heart's pumping phase

rapid heart rate, >90 beats per min in the adult

broader area of the heart's outline located at the 3rd right and left intercostal space
