The Cardiovascular System
What the 3 major types of blood vessels?
Arteries, Capillaries, Veins
Does the right atrium receive deoxygenated or oxygenated blood?
Deoxygenated
Does the right ventricle discharge deoxygenated or oxygenated blood?
Deoxygenated
Elastic or Conducting Arteries
Largest diameter arteries; walls contain large amounts of elastic fibers; allows arteries to expand and recoil; elastic fibers function as pressure reserve
Which side of the heart is the pump for the systemic circuit?
Left side
Does the left atrium receive deoxygenated or oxygenated blood?
Oxygenated
Does the left ventricle discharge deoxygenated or oxygenated blood?
Oxygenated
Which side of the hear is the pump for the pulmonary circuit?
Right side
How many chambers does the heart have? Name them.
There are 4 chambers. The left and right atria and the left and right ventricles.
Put the following vessels in the correct order in which a red blood cell would pass through to travel from the heart to a capillary bed. 1. Arterioles 2. Elastic arteries 3. Muscular arteries a) 2, 3, 1 b) 3, 1, 2 c) 1, 3, 2 d) 3, 2, 1 e) 1, 2, 3
a) 2, 3, 1
Put the following vessels in the correct order in which a red blood cell would pass through. 1. Venule 2. Capillary 3. Vein 4. Artery 5. Arteriole a) 4, 5, 2, 1, 3 b) 1, 2, 3, 4, 5 c) 3, 2, 1, 4, 5 d) 5, 2, 3, 1, 4 e) 4, 2, 5, 1, 3
a) 4, 5, 2, 1, 3
Blood vessels carrying blood away from the heart are called.. a) arteries b) plexuses c) capillaries d) veins e) venules
a) arteries
Capillary beds are drained by a) venules b) veins c) elastic arteries d) arterioles e) muscular arteries
a) venules
These vessels are where the exchange of materials between the blood and body tissues occurs. Which blood vessels are being described? a) Arteries b) Capillaries c) Venules d) Veins e) Arterioles
b) Capillaries
In which of these blood vessels are elastic fibers present in the largest amounts? a) Distributing arteries b) Conducting arteries c) Muscular arteries d) Arterioles e) Capillaries
b) Conducting arteries
Which two heart chambers contain oxygenated blood? a) Right ventricle and left ventricle b) Left atrium and left ventricle c) Right atrium and right ventricle d) Right atrium and left ventricle e) Right atrium and left atrium
b) Left atrium and left ventricle
The transport medium for the cardiovascular system is ______________. a) lymph b) venules c) blood d) arteries e) water
c) blood
Describe Arteries
carry blood AWAY from the heart; carries oxygenated blood in the systemic circulation; carried oxygen-poor blood in the pulmonary; smallest is an arteriole
Describe Veins
carry blood TOWARDS the heart; carries oxygen-poor blood in the systemic circulation; carries oxygenated blood in the pulmonary circulation; smallest is a venule
Capillaries
connect arterioles to venules; exchange vessels; sites of exchange of nutrients and waste products between the blood and tissue cells
Which of these vessels are most likely to contain valves? a) Arterioles b) Veins in the ventral body cavity c) Elastic arteries d) Muscular arteries e) Veins in the limbs
e) Veins in the limbs
The aorta is an example of a(n) ______________ artery. a) distributing b) sinusoid c) exchange d) muscular e) elastic
e) elastic
Venules
formed when several capillaries unite
Veins
formed when several larger venules unite
Muscular or Distributing Arteries
medium-sized arteries; walls contain large amounts of smooth muscle; important in regulating blood flow to specific body regions; smooth muscle cells are responsible for vasoconstriction and vasodilation
Arterioles
small arteries
Describe Capillaries
smallest blood vessels; thin wall; their main role is to allow the exchange of materials between blood and body tissues
