How big is a heart?
About the size of a fist.
What is the pericardium?
An outer covering, protecting and enclosing the heart.
What does the pericardial cavity do?
It contains fluid and reduces friction.
Outer layer of heart; reduces friction.
Middle layer of heart; mostly cardiac muscle.
Inside layer; contains blood vessels.
Valve located between an atrium and ventricle.
Indentation on the front of the heart.
Chordae Tendinae/Papillary Muscles
Muscles that hold the valves in place.
Large trunk that splits into left and right pulmonary arteries, which are the only arteries to carry deoxygenated blood.
Return oxygenated blood back to the body.
Delivers blood to the body.
Blood is forced out of ventricle, aortic valve opens; stands for the higher number in a blood pressure reading.
The aortic valve closes; stands for the lower number in a blood pressure reading.
What is the normal blood pressure?
What is the average heart rate?
What 4 factors affect blood pressure?
What makes the "lub-dub" sound in the heart?
The opening and closing of the valves.
What is known as the natural pacemaker?
The SA node, which generates impulses.
Carry impulses to the AV Node.
AV (Atrioventricular) Node
Sends impulses from atrium to ventricles. (A to V)
Sends impulse to wall of ventricles.
Send impulses to ventricles.
What is the formula for Cardiac Output?
Cardiac Output= Stroke Volume X Heart Rate
Small arteries that connect to capillaries.
Small veins that connect to capillaries and they have valves in them.
Penetrate tissues and allow exchange of materials.
Narrowing of the blood vessels.
Expanding of the blood vessels.
What are the factors of blood flow? (3)
1-Constriction of the diaphragm
2-Pumping action of the skeletal muscles
3-The valves in veins
Superior Vena Cava
Gets blood from the top part of the body.
Inferior Vena Cava
Gets blood from the bottom part of the body.
What does blood do?
It transports substances and maintains homeostasis.
How much of blood is made of cells?

What are the main functions of red blood cells?
To pick up carbon dioxide and transport oxygen.
Combines to transport carbon dioxide.
Means there is plenty of oxygen, and produces a bright red color.
Means there is not enough of oxygen, and produces a bluish-red color.
What is the main function of white blood cells?
To defend the body against disease-causing agents.
