Blood Vessels
The three tunics from superficial to deep
What are tunica externa, tunica media, and tunica intima
The first type of arteries directly leaving the ascending aorta are called?
What are coronary arteries
The most abundant blood vessels in the body are
What are capillaries
Arterial pathway from the heart to the heart itself
What is from the ascending aorta, to coronary arteries
Pressure wave detected at specific locations.
What is pulse
This tunic is thickest in arteries
What is tunica media
The first three branches off the aortic arch are?
What are the brachiocephalic, left common carotid and left subclavian.
Superior and inferior vena cava are examples of these
What are veins
Arterial pathway from the heart to the right arm.
What is the Aortic arch, brachiocephalic, right subclavian, right axillary, right brachial, right radial and ulnar.
The equation for determining blood pressure
What is Cardiac output (CO) multiplied by Peripheral Resistance (PR).
Capillaries are only made of this tunic
What is tunica intima
Capillaries RECEIVE blood from these small artery vessels.
What are arterioles
Fluid is reabsorbed into capillary beds through THESE vessels before returning to the veins
What are venules
The three branches off of the aortic arch are the
What are the brachiocephalic (which splits into the right subclavian and right common carotid), left common carotid, and left subclavian.
Blood pressure regulation involves 3 key variables
What are cardiac output (CO), Peripheral resistance and Blood volume
These are found in large veins to resist backflow
What are valves
Blood pressure is determined by these two arterial pressures.
What are systolic and diastolic pressures
This system of veins goes through the liver to remove toxins before supplying blood to your entire system
What is the hepatic portal system
Arterial pathway from the heart to the left foot.
What are the aorta, descending aorta, abdominal aorta, left common illiac, left femoral, left popliteal, ant & post. tibial and arcuate arteries
The nine pulse points are
What are carotid, superficial temporal, facial, brachial, radial, femoral, popliteal, posterior tibial and doralis pedis
The nervous system is able to _____________ and ____________ arteries to increase and decrease blood flow. (use appropriate terminology)
What is dilate and constrict.
Even though the heart is not constantly pumping, blood through is continuous because of these two factors.
What are the stretchiness of arteries and higher blood pressure.
Even though blood pressure is lower in veins, the body is able to resist gravity and return blood to the heart using these two measures.
What is "milking" by skeletal muscles, and one way valves.
Blood flow TO and FROM the myocardium.
aorta, rt and lft coronary arteries, marginal, post. interventricular/descending, circumflex, Ant. descending arteries; great cardiac vein, middle cardiac vein, small cardiac vein and ant. cardiac vein.
THIS pressure forces fluid OUT of capillary beds, while THIS pressure forces fluid INTO capillary beds.
What are Blood pressure and Osmotic pressure, respectively.
