Blood moves through blood vessels in which of the following sequences, starting from the heart?
arteries
Carry blood AWAY from the heart
veins
Carry blood TOWARD the heart
capillaries
Carry blood from arterioles to venules
venules
Which blood vessel carries blood away from the capillaries?
arteries and arterioles
Which blood vessel carries blood toward the capillaries?
tunica media
Which blood vessel muscle layer is usually thicker in the arties than in the veins?
tunica externa
Which layer of the blood vessel is made of tough connective tissue?
The endothelium has one-way valves.
Which of the following is NOT true of arteries? The endothelium has one-way valves, They have a thicker tunica media than veins, They carry blood away from the heart, They carry blood to arterioles.
They carry blood away from the heart
Which of the following is NOT true of veins? The endothelium has one-way valves, They have a thinner tunica media than arteries, They carry blood away from the heart, They receive blood from venules
The endothelium has one-way valves
Which of the following is not true of capillaries? They are made up of endothelium, The endothelium has one-way valves, They receive blood from arterioles, They are where material is exchanged with the cells.
Tunica intima (endothelium)
Which of the following is the smooth inner layer of the blood vessels?
ischemia
Which term refers to a decrease in blood supply to a tissue, leading to gradual cell death?
vein
blood carries vessel blood that from the carries digestive blood back system to the to heart
capillary
blood vessel in which the exchange of material between the blood and the body occurs
artery
blood vessel that carries blood away from the heart
veins
collect blood for return to the heart, low pressure vessels
arteries
distribution of nutrients, gases, etc with movement of blood under high pressure, assist in maintaining the arterial blood pressure
tunica externa
heavy layer - veins
tunica intima
inner layer of endothelial cells - arteries
tunica intima
inner layer, valves prevent retrograde movement of blood - veins
tunica intima
layer of the blood vessel also called the endothelium
capillaries
microscopic vessels, only layer is the tunica intima, exchange vessels for nutrients, wastes, and fluids
tunica media
smooth muscle, thick in arteries, important in blood pressure regulation - arteries
tunica media
smooth muscle, thin - veins
tunica media
the muscle layer of the blood vessel
tunica externa
the outermost layer of the blood vessel
tunica externa
thin outer layer of elastic tissue - arteries
