  • Front
  • Back
Is output for right and left ventricles the same or different?
the same
If cardiac output is 5, and the change in pressure is 100, what is the TPR? (hint: relate to flow)
What is the BP in pulmonary artery?
BP in pulmonary vein/left atrium is...
Flow in pulmonary circulation is (<,>, =) flow of systemic circulation
If pressure in pulmonary circulation is decreased, pressure in systemic circulation is (increased/decreased)
Pulmonary system has (more/less) resistance than systemic
systemic system has (more/less) resistance than pulmonary
____ = pulmonary arterial pressure - Left atrial pressure/pulmonary vascular resistance(PVR)
Cardiac output
force exerted on walls of vessel is....
Blood pressure
What is normal systemic arterial Blood pressure?
describe flow at Q1 and Q2.
explain why the flow is able to work this way...
At Q1: flow is intermittent or pulsative
At Q2: there is continuous flow.
Due to elasticity of arterial walls, stretch on heartbeat, recoil on relaxation, creating constant bloodflow at Q2.
if distensibility is reduced, systolic BP is (increased/decreased)
If stroke volume is increased, systolic BP is (increased/decreased)
if volume is increased at a certain capacity, Pressure is (increased/decreased)
Volume of fluid/capacity of system is ....
what two things might influence systolic BP
Stroke volume and distensibility
if distensibility is decreased, Arterial blood pressure (increases/decreases)
What changes diastolic BP?(3 things mentioned in class)
-arterial outflow (blood leaving arteries)
-Heart rate
- systolic BP
increasing outflow (increases/decreases) pressure
what controls blood leaving arterial tree?
Most of resistance to blood flow leaving arterial tree is through
Increasing TPR (increases/decreases) outflow leaving arterial tree which (increases/decreases) DBP
decreases outflow and increases DBP
decreasing TPR (increases/decreases) outflow leaving arterial tree which (increases/decreases) DBP
increases outflow and decreases DBP
Increasing HR, (Increases/decreases) DBP = (increases/decreased) outflow.
increased DBP, decreased outflow
Increasing SV = (increasing/decreasing) SBP = (increasing/decreasing) DBP
increasing SBP + DBP
dilation (increases/decreases) TPR
decreases(reduced by r^4)
constriction (increases/decreases) TPR
Why does increasing Heart rate increase Diastolic pressure?
less time for outflow before next beat making blood pump faster
What are ejection rates?
blood pumped into aorta
Partial state of contraction (kidney, skin, abdominals) is _______(1), is cause by ____(2) stimulation..
(1)vasomotor tone
If there was no sympathetic stimulation, how would that effect Vasomotor tone, TPR, and MABP?
decrease them all
medullar neurons stimulate _____(1) nerves, this causes _______(2)
(2)vasomotor tone
A vasomotor center is...
a collection of medullar neurons
Cardiac _____ center in medullary nerve can increase HR
Cardiac _____ center in medullary nerve can decrease HR
connective tissue around lung is called....
visceral pleura
_____ BP is affected by ejection rate
label all green parts
give pathway from nasal to trachea
nasal -> nasal sinuses -> pharynx ->trachea
what are three ways upper airways condition Oxygen
warming, filtering, humidifying
cartilage containing part of lungs are...
these are smaller than bronchi, no cartilage, and higher density of Smooth muscle relative to bronchi and trachea
They're 300 million of these and they are 1/3mm in diameter
alveolus make up airsac.
when the entire airway is made up of alveoli, this would be called the...
alveolar sac
conducting zone is...
region of lungs w/out alveoli
respiratory zone is...
region of lungs with alveoli
_____ have alveolus in wall
respiratory bronchioles
_____ have more alveolus than bronchioles but less that sac.
alveolar duct
T/F. air is 100% saturated w/ H20 vapor before it reaches trachea
The right lung has _#__(1) lobes, while the left lung has __#_(2) lobes.
(1) 3 lobes
(2) 2 lobes
