Occluded Blood Vessells
Blood
Is trapped, cannot
hear
Turbulent
Partially
occluded, blood hits walls and can
hear
Laminar
blood Vessells
Blood
flowing
smoothly
Regular

Systole -
120
first hear sound
Dystole -
80
end of sound
Pulse
pressure
Difference between
systole
&
dystole
Mean arterial Pressure
diastole +
1/3

Receptors
Chemoreceptors
- detect change in
02
or ph in blood
Baroceptors
- detect change in
blood pressure
Three branches of Aaorta
Left brachiocephalic
Left Common Carotid
Left subclavian artery
Left
brachiocephalic divides into
right
subclavian
Right
Common
Carotid
Common carotid
Internal
- runs directly to
base
of brain
External
- supply head and face with
blood
Subclavian
divides into
veritable arteries - runs up transverse foramen o cervical vertebrae, meets
basal
artery and joint circle of
willis
Subclavian travels
underneath clavicle
-
axillary artery
at first rib
axillary
artery
runs through armpit - becomes
brachial
artery
brachial
artery
contains;
Radial
artery - lateral,
thumb side
Ulna
artery - medial -
little fingerside
