The Atria
What does EKG stand for?
Electrocardiogram
There are 4 chambers and 4 valves within the heart. True/False
What is the primary function of the cardiovascular system?
1. To carry oxygen and nutrients throughout the body
2.To remove waste from the body
I am a blood cell returning from the body to the heart. What chamber of the heart am I in?
The Right Atrium
What are the gates that regulate the flow of blood in one direction?
Valves
What does an EKG measure?
The electrical activity of the heart
Cardiac muscle is striated, voluntary, and makes up the walls of the heart. True/False
False: Cardiac muscle is striated, involuntary, and makes up the walls of the heart.
How many gallons of blood are pumped through the heart each day?

Put the following steps in the correct order, starting with the Pulmonary Veins.( Several steps are skipped)
Pulmonary Veins, Aortic Valve, Left Ventricle, The body, Right Ventricle
Pulmonary Veins, Left Ventricle, Aortic valve, The Body, Right Ventricle
What heart valve regulates blood flow from the left atrium to the left ventricle?
Bicuspid valve/ Mitral Valve
What is the name of the specific cardiac cells that work to keep the pace of the heart?
Pacemaker cells
All veins carry deoxygenated blood. True/false
False
The pulmonary vein carries OXYGENATED blood
The fiber filled layer surrounding the heart is called the...

I am a blood cell traveling through the heart? How do I get from the Right Ventricle to Left ventricle. List all the steps in order.
1.Right Ventricle
2.Pulmonary Valve
3.Pulmonary Artery
4.The lungs
5.Pulmonary Veins
6.Left Ventricle
Which veins carry oxygenated blood?
The pulmonary veins
Where do electrical impulses start in the heart?
The SA node
Arteries always carry blood away from the heart. True/False
True
Which wave on an ekg is not seen in every patient?
What is the difference between Pulmonary Circulation and Systemic Circulation?
Pulmonary Circualtion- between the heart and lungs, blood becomes oxygenated
System circualtion- circulation of blood throughout the body, delivering oxygen to vital organs and removing waste.
What 2 chambers of the heart pump blood from the heart throughout the body?
The Ventricles
What is the end result of the electrical current passing through the heart?
The ventricles contract/ the heart pumps
The heart pumps/ moves all at once. True/False
False. The heart moves in a wave like motion.
