Exploring the Cardiovascular System

What are the four main chambers of the heart?

• right atrium, right ventricle, left atrium, left ventricle

• right atrium, right atrium, left ventricle, left ventricle

• aorta, pulmonary artery, vena cava, left atrium

• upper chamber, lower chamber, left chamber, right chamber

What is the function of the aorta?

• The aorta carries deoxygenated blood to the heart.

• The aorta carries oxygenated blood from the heart to the body.

• The aorta is responsible for filtering blood in the kidneys.

• The aorta regulates blood pressure in the lungs.

Name the type of blood vessel that carries oxygenated blood away from the heart.

• Artery

• Capillary

• Arterioles

• Vein

What is the role of the vena cava in the circulatory system?

• The vena cava carries oxygenated blood from the lungs.

• The vena cava pumps blood to the lungs for oxygenation.

• The vena cava returns deoxygenated blood to the heart.

• The vena cava is responsible for nutrient absorption in the intestines.

Identify the valve located between the left atrium and left ventricle.

• Mitral valve

• Aortic valve

• Pulmonary valve

• Tricuspid valve

What is the primary function of capillaries?

• Regulating blood pressure.

• Transporting oxygen to the lungs.

• Facilitating exchange of substances between blood and tissues.

• Storing nutrients for energy.

List two common symptoms of cardiovascular diseases.

• Headache, nausea

• Fatigue, fever

• Chest pain, shortness of breath

• Dizziness, rash

What is coronary artery disease?

• A type of cancer affecting the heart.

• A heart condition caused by high blood pressure.

• An infection of the heart valves.

• Coronary artery disease is a condition characterized by the narrowing or blockage of coronary arteries due to plaque buildup.

Define hypertension and its significance in health.

• Hypertension is a condition of low blood pressure that is harmless.

• Hypertension is a temporary increase in blood pressure that has no long-term effects.

• Hypertension is a type of heart disease that only affects older adults.

• Hypertension is a condition of elevated blood pressure that poses serious health risks.

What are the potential complications of untreated hypertension?

• Enhanced immune function

• Improved vision

• Increased energy levels

• Potential complications of untreated hypertension include heart disease, stroke, kidney damage, vision loss, and metabolic syndrome.
