(CVS) Blood Vessels + Systemic and Pulmonary Circulation Flashcards
The _________ circulation is the system of
blood vessels that moves oxygenated
blood between the heart and rest of the
body and returns deoxygenated blood
back to the heart.
systemic
The function of this structure is to exchange fluid, nutrients, electrolytes, hormones, and other substances between the blood and the interstitial fluid.
capillaries
The _____ (smallest veins) collect blood from the capillaries and gradually coalesce into progressively larger veins.
venules
This type of vein moves blood that contains waste and lacks oxygen from your capillaries to your veins.
It has a diameter slightly larger than that of capillaries and is composed of endothelium resting on a delicate connective tissue layer.
venules
In a muscular artery, this layer of blood vessels is composed of a layer of elastic connective tissue from the outer margin.
tunica media
This is the outermost layer of blood vessels, composed of dense connective tissue adjacent to tunica media.
tunica adventitia/externa
These transport blood from small-sized arteries to capillaries and are the smallest arteries. It only consists of only 1 or 2 layers of circular smooth muscle cells.
Arterioles
This vessel transports blood from the left ventricle of the heart through all parts of the body and back to the right atrium
systemic vessels
Vein of the body are normally classified into one of 4 categories:
venules
small veins
medium-sized veins
large veins
The wall of blood vessels is composed of three layers or tunics, they are _____, ____, and _____.
tunica intima
tunica media
tunica adventitia/externa
This type of blood vessel carries deoxygenated blood and transports it from different parts of the body to the heart.
Veins
The walls of this structure are very thin and consist only of endothelium.
capillaries
These include medium-sized and small arteries.
Medium-sized arteries are frequently called
“distributing arteries”.
Muscular arteries
This type of blood vessel carries oxygenated blood and transports it away from the heart to different parts of the body.
Arteries
In a muscular artery, this layer of blood vessels also contains a layer of thin elastic connective tissue.
