Anatomy
What vessel do all arteries branch from?
aorta
What is the term for high blood pressure?
hypertension
What type of vessels return blood to the heart?
venous (veins and venules)
What can we use to measure BP?
sphygmomanometer
cardi-
heart
T/F: All veins branch from the superior/inferior vena cava.
F; all veins MERGE into the superior/inferior vena cava. Remember the directionality of blood flow!
Describe an incident where the patient might present with shock.
any type of severe laceration or injury that results in an inadequate supply of blood to the body tissues
Which type of blood vessel is responsible for diffusion of gases and other substances?
capillaries
What is the normal value for DIASTOLIC BP?
80
enter-
intestines
Where do the carotid arteries supply blood to?
the head
What do you call a piece of a clot that breaks loose?
embolus
What is the muscle pump?
When muscles contract, they squeeze blood through the valves inside veins to help it return to the heart.
Where do phlebotomists commonly draw blood from?
median cubital vein
-pexy
suspension
What are the divisions of the aorta?
ascending, arch, descending (thoracic and abdominal)
What disorder is associated with a sclerotization of the inside of the vessel?
artherosclerosis
What is the respiratory pump?
The altering of thoracic pressures by breathing to assist in venous return of blood to the heart.
What are Korotkoff sounds?
The first pulsations heard after pressure is released from the sphygmomanometer when measuring BP.
braid
Which artery lies proximal to the brachial artery and distal to the subclavian artery?
axillary
Describe the relationship between an aneurysm and hemorrhaging.
An aneurysm is a bulging sac in a vessel due to weakness of the vessel wall that can rupture and cause profuse bleeding (hemorrhage).
Why do veins possess valves?
They lack the pressure generated by the thicker tunica media of arteries for pushing blood forward, so veins have valves to prevent backflow of blood.
Name 3 places where you can take a pulse just by feeling.
Neck (common carotid a.), Wrist (radial a.), Foot (Dorsalis pedis a.)
-asthenia AND -esthesia
weakness and sensation
