Answers.
be familiar with the principal structures of the ventilatory system - Answer nose,
pharynx, larynx, trachea, bronchi, bronchioles, alveoli
pharynx - Answer contain the tonsils; normal function is to fight infection
larynx - Answer voice box
epiglottis - Answer flexible cartilage that covers the opening of the trachea and
automatically closes the opening to the trachea when swallowing
trachea - Answer windpipe
bronchi - Answer two short branches located at the lower end of the trachea that carry
air into the lungs
bronchioles - Answer smallest branches of the bronchi
lungs - Answer right side has 3 lobes; left side has 2 lobes
alveoli - Answer tiny sacs of lung tissue specialized for the movement of gases
between air and blood
functions of conducting airways - Answer low resistance pathway for airflow, defense
against chemicals and other harmful substances that are inhaled, warming and
moistening the air
pulmonary ventilation (PV) - Answer inflow and outflow of air between the atmosphere
and the lungs (breathing)
total lung capacity (TLC) - Answer the volume of air in the lungs after a maximal
inhalation
vital capacity (VC) - Answer the maximum amount of air that can be exhaled after a
maximum inhalation
,tidal volume (TV) - Answer amount of air inhaled or exhaled with each breath under
normal breathing conditions
expiratory reserve volume (ERV) - Answer the volume of additional air that can be
forcibly exhaled after a normal exhalation
inspiratory reserve volume (IRV) - Answer additional inspired air over and above tidal
volume
residual volume (RV) - Answer volume of air contained in the lungs after maximal
exhalation
inspiratory capacity - Answer TV + IRV
expiratory capacity - Answer TV + ERV
explain the nervous and chemical control of ventilation during exercise - Answer
increase in carbon dioxide increases the blood acidity levels
be familiar with the role of hemoglobin in oxygen transportation - Answer hemoglobin
carries oxygen around the body as oxyhemoglobin in red blood cells
diffusion - Answer gas will move from an area of higher pressure to lower pressure
ventricles - Answer lower chambers of the heart
left ventricle - Answer pumps oxygenated blood to the aorta
right ventricle - Answer pumps deoxygenated blood to the pulmonary artery
atrium - Answer upper chambers of the heart
right atrium - Answer receives blood from the body via the superior/inferior vena cava
left atrium - Answer receives oxygenated blood from the lungs via the pulmonary
veins
bicuspid valve - Answer between left atrium and left ventricle
tricuspid valve - Answer valve between the right atrium and the right ventricle
aortic valve - Answer between left ventricle and aorta
pulmonary valve - Answer between right ventricle and pulmonary artery
,superior/inferior vena cava - Answer carries deoxygenated blood from the body to the
right atrium
pulmonary vein - Answer carries oxygenated blood from the lungs to the heart
pulmonary artery - Answer carries deoxygenated blood from the heart to the lungs
erythrocytes - Answer red blood cells
leukocytes - Answer white blood cells
thrombocytes - Answer platelets
plasma - Answer liquid portion of blood
red blood cell function - Answer carries oxygen and iron throughout the body
white blood cells function - Answer fight infection
platelets - Answer blood clotting
aorta - Answer large artery that takes blood from heart to the body
arteries - Answer blood vessels that carry blood away from the heart
veins - Answer blood vessels that carry blood back to the heart
pulmonary circuit - Answer heart to lungs to heart
systemic circuit - Answer heart to body to heart
sinoatrial node (SA node) - Answer pacemaker of the heart
extrinsic regulation of the heart - Answer autonomic nervous system- sympathetic and
parasympathetic
sympathetic - Answer fight or flight
parasympathetic - Answer rest and digest
heart rate - Answer number of beats per minute
cardiac output - Answer the amount of blood pumped from the heart in one minute
stroke volume - Answer the amount of blood pumped by each ventricle in each
contraction
, cardiovascular drift - Answer slow but constant increase in heart rate during prolonged
activity (ex: increase of body temperature)
blood pressure - Answer the pressure that is exerted by the blood against the walls of
blood vessels
systolic - Answer blood pressure in the arteries during contraction of the ventricles
diastolic - Answer blood pressure in the arteries during relaxion of the ventricles
VO2 max - Answer the maximum amount of oxygen the body can take in and use
during exercise
VO2 max equation - Answer Q(CaO2 - CvO2)
skill - Answer learned ability
motor skills - Answer more movement than thinking (running)
cognitive skill - Answer a skill that requires problem solving or the application of
strategies (chess)
perceptual skill - Answer reading the environment (putt in golf)
perceptual-motor skill - Answer adapting to environment and interpret it (football)
continuum - Answer a line where skills can be placed and classified
discrete skills - Answer skills that have a distinctive beginning and end that can be
identified (golf swing)
serial skills - Answer collective sequences of multiple discrete skills (triple jump)
continuous skills - Answer movement skills that appear to have no recognizable
beginning or inherent beginning and end (cycling)
open skills - Answer environment is variable and unpredictable (jumping for a rebound
in basketball)
closed skill - Answer environment is stable and predictable (archery)
gross motor skills - Answer large body movements (running)
fine motor skills - Answer physical skills that involve the small muscles and eye-hand
coordination (playing piano)
