False
What is the main purpose of the coronary arteries?
To supply oxygenated blood to the heart muscle
Where are the coronary vessels located in relation to the heart muscle?
On the exterior of the heart
What is the direction of blood flow in the coronary veins?
From the heart muscle to the right atrium
What is the function of the fat lines where the coronary vessels are located?
To provide structural support to the coronary vessels
What is the relationship between the coronary arteries and the aorta?
The coronary arteries are branches of the aorta
Match the following components of the coronary circulation with their functions:
Coronary arteries = Supply oxygenated blood to the heart muscle Coronary veins = Drain deoxygenated blood from the heart muscle Aorta = Receive oxygenated blood from the coronary arteries Interventricular grooves = House the coronary vessels in fat lines
Match the following locations with the structures they relate to:
Base of the aorta = Origin of coronary arteries Right atrium = Receiver of deoxygenated blood from coronary veins Exterior of the heart = Location of coronary vessels Interventricular grooves = Location of coronary vessels in fat lines
Match the following components of the coronary circulation with their characteristics:
Coronary arteries = Oxygenated blood supply to the heart muscle Coronary veins = Deoxygenated blood drainage from the heart muscle Coronary vessels = Located on the exterior of the heart Fat lines = Location of coronary vessels in interventricular grooves
Match the following with their roles in the coronary circulation:
Coronary arteries = Deliver oxygenated blood to the heart muscle Coronary veins = Return deoxygenated blood to the right atrium Fat lines = House coronary vessels in interventricular grooves Aorta = Source of oxygenated blood for coronary arteries
Match the following structures with their relationships:
Coronary arteries = Branch from the aorta Coronary veins = Drain into the right atrium Coronary vessels = Located in fat lines on the heart's exterior Interventricular grooves = House coronary vessels in fat lines

Pumping blood throughout the body
What is the composition of the pericardium?
Two connective tissue layers
Learn about the coronary arteries and veins that supply oxygen and nutrients to the heart muscle itself. Understand how the coronary vessels originate from the aorta and drain into the right atrium. Test your knowledge of coronary circulation and heart function!
