Cardiovascular System
The 3 Main Structures of the Cardiovascular System
What is Heart, Blood Vessels, and Blood?
The chambers of the heart that collect the blood from your lungs/body.
What is the Left and Right Atrium
The small blood vessels that do the exchanging between arteries and veins
What is capillaries
Chronically high blood pressure is medically referred to by this term
What is hypertension
The yellowish, liquid component that makes up majority of your total blood volume
What is plasma
The main functions of the cardiovascular system (3)
What is
1. circulating blood throughout the body
2. transports nutrients and oxygen
3. removes co2 and bodily wastes
The role of arteries
What is bringing blood AWAY from the heart?
Known as the heart's natural pacemaker
What is the SA Node
What is systolic pressure
These components of blood clump together and form clots, preventing you from losing too much blood from a cut.
What is platelets
When blood travels from the heart to the body cells and back to the heart
What is systemic circulation?
To prevent blood from flowing backward when the ventricles contract, the heart relies on these mechanical structures.
What are valves
Without the electrical delay provided by this specific node, the ventricles would contract too early, preventing the heart from filling properly with blood.
What is AV node
This medical term describes abnormally low blood pressure, which can sometimes cause dizziness or fainting, but for some no symptoms.
What is hypotension
These proteins circulate in your plasma to defend the body, but during a bad transfusion, they will attack unknown antigens.
What is antibodies
When you are too hot, the body opens up blood vessels near the skin to release heat, a process known by this scientific term.
What is vasodilation
The two veins bringing blood into the heart
What is the superior/inferior vena cava and pulmonary vein?
These electrical pathways are spread out across the walls of the ventricles, triggering them to pump blood out from the ventricles.
What is purkinje fibers
Consuming too much sodium, chronic stress, smoking/drinking alcohol, and a lack of exercise are all major triggers that cause this dangerous state
What is hypertension
Individuals with this specific blood type lack antibodies A, antibodies B, and Rh antibodies.
What is Type AB+ (universal recipient)
This circulatory system pumps deoxygenated blood to the lungs and returns oxygen-rich blood to the heart.
What is the pulmonary circulatory system?
This specific type of blood is found in the right side of the heart and is headed toward the lungs to dump carbon dioxide waste.
What is deoxygenated blood
While the heart's conduction system generates its own rhythm, this body system constantly sends signals to the SA node to speed up or slow down your heart rate based on stress or rest.
What is the nervous system
The bottom number in a blood pressure reading, known as diastolic pressure, specifically measures this from your heart
What is your heart relaxing (heart relaxing between beats)
Because it lacks A, B, and Rh antigens on its surface, this specific blood type is celebrated as the universal donor.
What is O-
