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 four regions of the aorta are?
What are the ascending aorta, aortic arch, thoracic aorta (also called descending), and abdominal aorta.
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.
Which veins drain into the hepatic portal vein before going through the hepatic portal system?
What are the splenic, gastric, and mesenteric veins.
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
Major arterial branches off the abdominal aorta (must get at least 9/10 for correct answer).
What are the celiac, splenic, gastric, hepatic, superior and inferior mesenteric, renal, gonadal, lumbar, and common iliac.
The four ways fluid can leave a capillary bed.
What are fenestrations, pores, diffusion, and vesicle transport.
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 brain.
What are is aortic arch, common carotid, internal carotid, circle of willis.
Circle of willis, internal carotid, internal jugular, and vertebral all drain into the brachiocephalic, and then into the superior vena cava.
THIS pressure forces fluid OUT of capillary beds, while THIS pressure forces fluid INTO capillary beds.
What are Blood pressure and Osmotic pressure, respectively.
