Question

blood pressure is
the force the heart exerts against the walls of arteries as it pumps the blood out to the body
the number of times your heart beats per minute
what is optimal range for blood pressure?
120/80
100/90
150/120
cardiac arrest occurs when electrical impulses in the heart become rapid or chaotic, which causes the heart to suddenly stop beating.
true
false
heart attack occurs when the blood supply to part of the heart muscle is blocked.
true

Explanation:

• First Question: Blood pressure is defined as the force the heart exerts against the walls of arteries as it pumps blood out to the body. The number of times the heart beats per minute is heart rate.
• Second Question: The optimal blood pressure range is generally considered to be 120/80 (systolic/diastolic). Values like 100/90 may be low for some (depending on context), and 150/120 is hypertensive.
• Third Question: Cardiac arrest occurs when the heart's electrical impulses become rapid or chaotic (like in ventricular fibrillation), causing the heart to stop effective pumping (sudden stop of beating in a sense of no - effective circulation).
• Fourth Question: A heart attack (myocardial infarction) occurs when the blood supply to a part of the heart muscle is blocked (usually by a blood clot in a coronary artery).

Answer:

• First Question: The force the heart exerts against the walls of arteries as it pumps the blood out to the body
• Second Question: 120/80
• Third Question: True
• Fourth Question: True
