Controls movement and balance.
Regulates body temperature only.
Which of the following is NOT a component of the cardiovascular system?

Heart
Blood vessels
Blood
What does cardiovascular health refer to?
How well your heart and blood vessels function together.
How fast your muscles grow.
How much oxygen you breathe in.
How quickly you digest food.
A healthy cardiovascular system maintains all of the following EXCEPT:
High blood sugar levels
Normal heart rate and rhythm
Stable blood pressure
Clear, flexible arteries
What can disrupt circulation in the body?
Blocked, reduced, or irregular blood flow
Increased bone density
Improved muscle strength
Faster digestion
Which condition is caused by fatty deposits building up in arteries?
Atherosclerosis
Stroke
Hypertension
Heart attack
What is the effect of a heart attack (myocardial infarction) on the body?
Part of the heart is damaged or dies.
Brain cells die due to lack of oxygen.
Blood pressure becomes too low.
Bones become weaker.
What happens during a stroke?
Blood flow to the brain is blocked or leaks, causing brain cells to die.
Fatty deposits build up in arteries.
The heart beats too quickly.
The lungs fill with fluid.
What is a possible effect of hypertension (high blood pressure)?
Damages arteries and strains the heart.
Improves blood flow to the brain.
Strengthens the heart muscle.
Reduces risk of heart attack.
What is anemia?
Low red blood cell count or hemoglobin.
High blood pressure.
Irregular heartbeat.
Excess cholesterol in the blood.
Which of the following is a symptom of anemia?
Cells receive less oxygen, leading to fatigue and weakness.
Chest pain or pressure.
Irregular heartbeat.
High cholesterol.
What is arrhythmia?
Irregular heartbeat.
Low red blood cell count.
High blood pressure.
