Cardiovascular System Flashcards
What is the cardiovascular system?
-The requirement for a circulatory system is a consequence of increasing size and complexity of multicellular organisms
-Provides a concentration gradient from the blood to cells for nutrients and in the opposite direction for waste
What is the primary and secondary roles of the circulatory system?
What are the 3 types of transport in the circulatory system?
What are the two serial circuits that stem from the heart?
Pulmonary circuit:
-Lungs
-Pulmonary capillaries
Systemic circuit:
-Systemic arterioles, capillaries and venules
-In all organs and tissues except the lungs
Explain vasculature in the cardiovascular system
Label the important parts of the heart
Explain the transport of blood through the heart and major blood vessels
How does blood flow through the cardiovascular system?
What is the source of pressure in the cardiovascular system?
Explain how pressure gradients influence fluid flow
What opposes flow and how can you predict it?
How does vessel radius influence blood flow?
How does vessel length and liquid viscosity influence blood flow?
How does velocity of flow differe from flow rate?
What is the pericardium?
Describe Atrioventricular valves (AV)
Describe Semilunar valves
Explain the cardiac conduction system
