chamber of the heart right ventricle
responsible for pumping blood
into pulmonary circulation
True or False false
Diastolic refers to contraction
of heart muscle
True or False false
An ECG is a tracing of an AP of
a cardiac muscle cell
Is there pressure when dealing Yes! Always
with fluids?
resistance= resisting flow
flow rate volume/time (L/min) (mL/min)
velocity of flow distance/time (cm/min) (mm/sec)
the unit Q refers to... flow rate
In Cardiac Myofiber Excitation activates the Sarcoplasmic Reticulum
Contraction Coupling,
letting Ca 2+ in does what?
force developed= # of cross bridges
Frank Starlings Law show the proportional
______________ relationship between
length and force
rapid depolarization is the result voltage gated Na+ channels
of...
, the benefit of no cardiac allows the heart to act autorythmically, not reliant on the build
muscle tetanus... of up force in order to reach an AP-->contract
contracting--> muscle cells
conducting--> autorhythmic cells
what 2 things need to happen 1. pace maker potential (I subset f)
for a cardiac muscle cell to 2. T-Type voltage gated Ca 2+ channels
reach threshold?
T/F F
Pace maker potential will take you need the pacemaker potential first, then the T-Type voltage
you all the way up to threshold gated Ca 2+ channels to take you the extra distance
potential
What is special about "Funny They allow movement of both Na+ and K+
Channels"?
What is the general rule of Na+ > K+
thumb when considering the
movement of Na+ and K+
which of the following ion c) L type voltage gated Ca2+ channels: conduction fiber
channel and cell type is paired
correctly?
a) I(f) voltage gated Na+
channels: contracting myofiber
b) T type voltage gated Ca2+
channels: contracting fibers
c) L type voltage gated Ca2+
channels: conduction fiber
d) all are correctly paired
!!! rule electrical, mechanical
