Right Atrium
What are the three main parts of the circulatory system?

2. Blood vessels
3. Blood
What causes a blockage in the blood vessels?
Build up of plaque (cholesterol)
What is one function of the Circulatory System? (BONUS 200 points: Name three functions)
1. Deliver oxygen to the body
2. Expel waste (CO2)
3. Deliver nutrients to the body
4. Temperature regulation
5. Fight Infection
120/80 mm Hg
Which side of the heart contains deoxygenated blood?
Right side
How many chambers are there in the heart? (BONUS 200 Points: Name all four)
4 --> Right and Left Atrium; Right and Left Ventricle
How do you repair a blockage?
Inserting a stent into the blood vessel and inflating it, which widens the blood vessel.
What are the four components of blood? Which one makes up the majority of the blood
1. Red blood cells (RBC)
2. White blood cells (WBC)
3. Plasma --> majority of blood
4. Platelets
What is an artery someone can use to measure their heart rate using their pointer and middle fingers? (BONUS 200 points: Name two)
1. Carotid artery
2. Radial artery
What chamber of the heart sends oxygenated blood to the aorta?
Left ventricle
What blood vessel carries blood away from the heart?
Arteries
What is the heart disease described as excessive force against arterial walls, causing strain on the heart and blood vessels.
Hypertension
What determines someone's blood type?
The type of surface protein present (antigen)
What does the top number of blood pressure represent? What does the bottom number of blood pressure represent?
1. Systole - Contractile stage
2. Diastole - Relaxation stage
What is another name for the bicuspid valve?
Mitral valve
Where does gas exchange occur? (HINT: A type of blood vessel)
Capillaries
What heart disease is characterized by an irregular heartbeat (too fast, too slow, or erratic) that is caused by a problem with the heart's electrical signals?
Arrhythmia
Which blood type has both antigens present? Which blood type has no antigens present?
1. AB Blood
2. O Blood
What is blood pressure?
The amount of force exerted on the walls of arteries.
Describe the difference between the Pulmonary circuit and the Systemic circuit of the heart (pathway of blood).
1. Pulmonary Circuit: Deoxygenated blood from the body is collected in the right atrium, flows to the right ventricle, and is then pumped and sent to the lungs to become oxygenated through the pulmonary artery.
2. Systemic Circuit: Oxygenated blood from the lungs is sent to the left atrium via the pulmonary veins, then sent to the left ventricle, which pumps the blood to the aorta and out to the body.
Which side of the heart is stronger and why?
2. Left side pumps blood to the body, while the right side pumps blood to the lungs
An artificial pacemaker replaces the action of what structure in the heart that initiates the action potential that tells the heart to contract?
1. Sinoatrial Node (SA Node)
What could happen if someone receives an incompatible blood transfusion?
1. Blood clots
2. Blockages
3. Heart Attack
Describe how to take someone's blood pressure.
1. Place a blood pressure cuff on their upper arm.
2. Make sure the bulb valve is shut and you have the stethoscope set up --> In your ears and the end on the inside of the patient's arm, right above the elbow.
3. Squeeze the bulb until you reach 180/200, then slowly undo the dial of the bulb and listen for the PSHHH sound (systole number).
4. Continually release the air in the bulb until the PSHHH sound can no longer be heard (diastole number).
5. Remove the blood pressure cuff and stethoscope.
