Basic Anatomy
What is the main organ of the Circulatory system
Heart
What pumps blood to the lungs
Pulmonary Arteries
Where is blood pressure the highest
Arteries
What is an EKG
Shows the electrical activity of the heart, providing a visual representation of the heart's rhythm and electrical signals
What is the covering of the heart called
Pericardium
What body cavity is the heart located in
Mediastinum
What recives blood back to the heart
Pulmonary Veins
Where is blood pressure the lowest
Veins
What does the P wave represent
The electrical depolarization of the atria
What is the scientific term for a heart attack
Myocardial infraction
What is the first chamber of the heart the de-oxygenated blood goes through
Right Atrium
True or False, pulmonary arteries carry oxygenated blood to the lungs
False
What is systolic pressure
Venricles contract
What does the QRS complex represent
It represents the electrical depolarization of the ventricles
What is a systolic contraction
Contraction of the heart where blood gets pumped from the chambers into the arteries
What is the muscle tissue of the heart called
Myocardium
What tiny vessels does blood need to flow through to reach the capillaries?
Venules and Arterioles
What is blood pressure gradient
The difference in pressure between two points in the circulatory system
What is a pacemaker used for
What is a reason for why someones BP would be high
Age, family history, obesity, diabetes, kidney disease, unhealthy diet, pregnancy
What are the two other ways to refer to the left AV valve
Mitral valve and the bicuspid valve
Explain how de-oxygenated blood from the body flows to the lungs
Vena Cava, Right Atrium, Right AV valve, Right Ventricle, Pulmonary SL Valve, Pulmonary Arteries, Lungs
What is the scientific term for blood loss causing blood pressure to lower
Hemorrhage
What could an abnormal QRS complex be related to in the heart
Primarily related to how the heart's electrical signals are conducting through the ventricles
What could happen if the AV node is damaged
Can lead to a heart block
