Cardiovascular System: Blood Vessels Flashcards
Anatomy, Physiology, and a few Pathophysiology! (40 cards)
Instead of classifying a blood vessel based on the blood they carry, they are based on direction instead. Which blood vessels carry blood AWAY from the heart?
Arteries
Instead of classifying a blood vessel based on the blood they carry, they are based on direction instead. Which blood vessels carry blood TOWARDS from the heart?
Veins
Most of the exchange that occurs between the blood
and interstitial spaces occurs across the thin walls of these tiny blood vessels.
Capillaries
There are three types of Capillaries. Which type are less permeable to large molecules than are other capillary types; they are in muscle, nervous tissue, and many other locations?
Continuous Capillaries
There are three types of Capillaries. Which type are in tissues where capillaries are highly permeable, such as the intestinal villi, ciliary processes of the eyes, choroid plexuses of the central nervous system, and glomeruli of the kidneys?
Fenestrated Capillaries
There are three types of Capillaries. Which type are capillaries that fenestrae that are larger than those in fenestrated capillaries, and gaps can exist between endothelial cells.
These capillaries occur in places where large molecules move into the blood, such as endocrine glands.
Sinusoidal Capillaries
Blood flow is regulated in the capillary branches by ________ ________, smooth muscle cells located at the origin of the branches
precapillary sphincters
The ends of capillaries closest to the arterioles are ________ capillaries
Arterial Capillaries
The ends of capillaries closest to the venules are ________ capillaries
Venular Capillaries
The three tunics of Arteries and Veins.
Tunica Intime (Inner)
Tunica Media (Middle)
Tunica Adventitia (Outer)
There are three types of arteries. What is the Aorta classified as?
Elastic Artery
There are three types of arteries. What is the Vena Cava classified as?
The Vena Cava is not an artery
This one was on purpose. I can’t let you feel complacent.
What structure among vein blood vessels prevent the back flow of blood?
Valves
This results from a loss of elasticity in the aorta, large arteries,
and coronary arteries.
Arteriosclerosis
is the deposition of material in the walls of arteries to form distinct plaques. It is a common type of arteriosclerosis.
Atherosclerosis
Greek words athero - meaning gruel or paste
This results from smooth muscle contraction and causes a DECREASE in blood vessel diameter, thereby decreasing blood flow through the vessel.
Vasoconstriction
can’t word it as narrowing of the vessel, that’d be offensive to your comprehension
This results from smooth muscle relaxation and causes an INCREASE in blood vessel diameter, thereby increasing blood flow through the vessel.
Vasodilation
can’t word it as widening of the vessel, that’d be offensive to your comprehension
These vessels are also called conducting arteries because they are the FIRST to receive blood FROM THE HEART, blood pressure is relatively high and fluctuates between systolic and diastolic values due to the pumping action of the heart.
Elastic Arteries
These vessels are frequently called distributing arteries because the smooth muscle cells allow them to partially regulate blood supply to different body regions by either constricting or dilating.
Muscular Arteries
These vessels are the smallest arteries in which the three
layers can be identified. They transport blood from small arteries to
capillaries.
Arterioles
These veins begin in a primary capillary network, extend some distance, and end in a secondary capillary network. This connection is unique in that there is NO PUMPING MECHANISM like the heart between the two capillary networks.
Portal Veins
This result when the veins of the lower limbs are
stretched to the point that the valves become incompetent.
Because of the stretching of the vein walls, the flaps of the valves
no longer overlap to prevent the backflow of blood.
Varicose Veins
This condition which leads to tissue death caused by a reduction in or loss of blood supply due to severe inflammation and stagnant blood flow in a large area.
Gangrene
There are three majoring arteries branching from the aortic arch. Which major branch do the left subclavian and left common carotid originate from?
Both Arteries are independent and major branches
It is the right common carotid and right subclavian arteries that are dependent of the brachiocephalic artery.
