What happens when you squeeze the pump? What does that represent in your body?

The liquid moves, just like blood being pumped by the heart.

100

Why might a clogged artery cause a heart attack?

It blocks blood flow to the heart, which can stop it from getting oxygen.

100

This chamber of the heart receives oxygenated blood from the lungs

left atrium

100

This condition occurs when the blood flow to the heart muscle is blocked, often by a clot in the coronary arteries.

heart attack (myocardial infarction)

100

This is the only artery in the human body that carries deoxygenated blood.

pulmonary artery

200

How would the system change if the "heart" pumped more slowly or more quickly? What impact would that have on the body?

Too slow = not enough oxygen, too fast = extra strain on the heart.

200

How could exercise help prevent these problems?

It keeps blood vessels healthy and reduces plaque buildup.

200

This valve prevents backflow of blood from the right ventricle to the right atrium.

tricuspid valve

200

This term refers to high blood pressure, a major risk factor for heart disease.

hypertension

200

This organ pumps about 2,000 gallons of blood through your body every day.

the heart

300

What would happen if an artery were clogged or blocked in this experiment? How does that relate to real health issues like heart disease?

The liquid wouldn't flow well, just like blood struggling to reach the heart in heart disease.

300

What foods could clog arteries?

Fried foods, fast food, processed meats, and foods high in bad fats.

300

This part of the heart pumps oxygenated blood to the rest of the body.

left ventricle

300

This type of cholesterol is often referred to as "bad cholesterol" and can contribute to plaque buildup in arteries.

LDL (low-density lipoprotein)

300

These tiny blood vessels are so small that red blood cells must pass through them in single file.

capillaries

400

What would happen if you added more "blood" (liquid) to the model? How would that affect circulation?

It could increase pressure, like high blood pressure in the body.

400

Why do doctors check blood pressure?

High blood pressure can damage arteries and lead to heart disease.

400

These blood vessels supply the heart muscle with oxygen and nutrients.

coronary arteries

400

This heart condition is characterized by an irregular or abnormal heartbeat.

arrhythmia

400

This is the approximate length of all the blood vessels in an adult human body if laid end to end.

100,000 Km or 62,000 miles

500

What do you notice about the movement of the liquid? How does it mimic real circulation?

It moves in pulses, like blood flowing through veins and arteries.

500

How could smoking affect the heart?

It narrows blood vessels, raises blood pressure, and increases heart disease risk.

500

This structure acts as the heart's natural pacemaker and initiates the heartbeat.

sinoatrial (SA) node

500

This procedure involves using a balloon to open blocked arteries and restore blood flow to the heart.

angioplasty

500

This is the name of the protein in red blood cells that binds to oxygen and gives blood its red color.
