This chamber of the heart pumps blood to the lungs.

What is the right ventricle?

100

This structure is known as the natural pacemaker of the heart.

What is the SA node?

100

These tiny air sacs are where gas exchange occurs.

What are alveoli?

100

The movement of air into the lungs is called this.

What is inspiration?

100

Swelling in the legs due to heart failure is called this.

What is edema?

200

This valve is located between the left atrium and left ventricle.

What is the mitral (bicuspid) valve?

200

This phase of the cardiac cycle is when the ventricles contract.

What is systole?

200

This muscle is primarily responsible for breathing.

What is the diaphragm?

200

The exchange of oxygen and carbon dioxide occurs by this process.

What is diffusion?

200

Chest pain caused by reduced blood flow to the heart muscle is called this.

What is Angina?

300

The heart is located in this area of the thoracic cavity.

What is the mediastinum?

300

Cardiac output is calculated by multiplying heart rate by this.

What is stroke volume?

300

This structure connects the larynx to the bronchi.

What is the trachea?

300

This gas increase acidity in the blood.

What is CO2 (Carbon Dioxide)?

300

This cardiovascular emergency occurs when blood flow to part of the heart muscle is blocked, causing tissue death.

What is myocardial infarction?

400

This blood vessel carries oxygenated blood away from the heart to the body.

What is the aorta?

400

This occurs when the heart cannot pump effectively to meet the body’s needs.

What is heart failure?

400

 This membrane surrounds the lungs and reduces friction.

What is the pleural membrane?

400

This part of the brain sends signals to regulate breathing patterns.

What is the brainstem?
