Medical Terminology
What is the scientific term for "high blood pressure"?
Hypertension
What type of blood vessel carries blood towards the heart?
Veins
What is the primary function of the heart?
To pump blood throughout the body
What is the range for normal blood pressure?
(Less than) 120/80
How many gallons of blood does a typical human heart pump daily?
2000 gallons
What is the scientific term for "heart attack"?
Myocardial infarction
What small blood vessel is the site for gas and nutrient exchange?
Capillaries
What phase of the cardiac cycle is responsible for ventricular contraction and blood ejection?
Systole
What is the range for a normal, resting heart rate?
60 - 100 bpm
Statistically, what specific day of the week is the most common day for people to suffer a heart attack?
Monday
What is the scientific term for "fast heart rate"?
Tachycardia
What layer of the heart is responsible for contraction and is the thickest?
Myocardium
What is the equation for Cardiac Output?
Heart rate x Stroke volume
What are two ways of measuring heart rate?
Carotid and brachial artery pulse
What animal holds the record for the largest heart of any mammal; it weighs over 1,000 pounds and is roughly the size of a bumper car.
Blue whale
What is the scientific term for "reduced blood flow to tissue"?
Ischemia
What is the pathway deoxygenated blood takes to become oxygenated and perfuse the body?
Right atrium → right ventricle → pulmonary artery → lungs → pulmonary vein → left atrium → left ventricle → aorta → body
Termed the “heart’s natural pacemaker”, what initiates the heartbeat?
Sinoatrial node/SA node
What respiratory rate is considered “hyperventilation”?
Greater than 20 breaths per minute
Every day, the human heart creates enough energy to drive a large truck for approximately this many miles:
20 miles
What is the scientific term for "stroke"?
Cerebrovascular accident
What part of the heart anchors the AV valves, preventing valve prolapse into the atria?
Chordae Tendineae
What is the Frank-Starling Law?
Increased venous return leads to increased preload, which increases the stretch of the muscle fibers to generate a more forceful contraction
What range of values is considered hypoxic for normal, healthy individuals, and what does that percentage represent?
Less than 95%. The percentage represents oxygen-saturated hemoglobin in the blood
Every single cell in the human body receives blood from the heart except for this part of the eye, which gets its oxygen directly from the air.
