Anatomy of the Heart
Where is the heart located?
Thoracic cavity
What is diastole in the cardiac cycle?
Relaxation of the heart chambers
What is the role of the SA Node in the heart's electrical conduction system?
Initiates the electrical impulse
what type of blood do veins normally carry
deoxygenated blood
What is the primary function of the left ventricle?
Pumping oxygenated blood to the body
What is the function of the pulmonary artery?
Carrying deoxygenated blood to the lungs
Why is the electrical conduction system important for maintaining a regular heartbeat?
It coordinates heart muscle contractions
How many chambers are in the heart and what are they called?
Four

Which valve is located between the right atrium and right ventricle?
Tricuspid valve
What are the 3 types of Blood Vessels?
Arteries, Veins, Capillaries
What is the primary function of the aorta?
Pumping oxygenated blood to the body
SA Node, AV Node, Bundle of His, and Purkinje fibers coordinate the heart's electrical signals
Electrical Conduction System
What is the role of coronary arteries in the cardiovascular system?
Supply oxygenated blood to the heart muscle
Major Blood Vessels
Aorta
Superior and Inferior Vena Cava
Pulmonary Artery and Veins
Normal Blood Pressure Range
Less than 120/80 mmHg
Thin wall that separates the atrium
septum
Thin inner lining of the heart
Endocardium
What are the heart and the circulatory system know as?
The heart and circulatory system, also known as the cardiovascular system, play a pivotal role in maintaining blood flow and delivering essential nutrients throughout the body
Components of Blood Pressure
Systolic Pressure/Diastolic Pressure
Where does the pulmonary artery take the blood: from the heart to the __________
Lungs to pick up O2
