Unit 3- Cardiovascular System Quiz

What are the four chambers of the heart and their functions?

• Upper atrium, lower atrium, upper ventricle, lower ventricle

• Front atrium, back atrium, front ventricle, back ventricle

• Right atrium, right ventricle, left atrium, and left ventricle

• Left chamber, right chamber, upper chamber, lower chamber

Explain the pathway of blood flow through the heart, including the pulmonary and systemic circuits.

• The pulmonary and systemic circuits are not involved in the pathway of blood flow through the heart.

• The pathway of blood flow through the heart involves the pulmonary and systemic circuits.

• Blood flows through the heart in a random pattern with no specific pathway.

• The pathway of blood flow through the heart involves the digestive and excretory circuits.

Describe the role of the atrioventricular valves and semilunar valves in the heart.

• They regulate blood pressure in the heart.

• They control the heart rate.

• They prevent backflow of blood in the heart.

• They produce red blood cells in the heart.

What is the difference between systemic circulation and pulmonary circulation?

• Systemic circulation occurs in the lungs, while pulmonary circulation occurs in the rest of the body.

• Systemic circulation carries blood to the brain, while pulmonary circulation carries blood to the heart.

• Systemic circulation carries blood to the body, while pulmonary circulation carries blood to the lungs.

• Systemic circulation carries oxygenated blood, while pulmonary circulation carries deoxygenated blood.

What are the common cardiovascular diseases and their impact on the body?

• Common cardiovascular diseases include coronary artery disease, heart failure, and stroke. These diseases can lead to serious complications such as heart attack, arrhythmias, and damage to the heart muscle.

• Common cardiovascular diseases include the flu, diabetes, and arthritis. These diseases have no impact on the body.

• Common cardiovascular diseases include lung cancer, liver disease, and kidney failure. These diseases can lead to improved heart health.

• Common cardiovascular diseases include asthma, allergies, and eczema. These diseases have no connection to the heart.

Explain the causes and symptoms of coronary artery disease.

• Coronary artery disease is caused by the buildup of plaque in the arteries, leading to reduced blood flow to the heart. Symptoms include chest pain, shortness of breath, and fatigue.

• Coronary artery disease is caused by excessive exercise

• Symptoms of coronary artery disease include fever and headache

• Coronary artery disease is caused by a virus

Describe the structure and function of the four main parts of the heart.

• Upper Atrium, Lower Atrium, Upper Ventricle, Lower Ventricle

• Left Atrium, Right Atrium, Left Ventricle, Right Ventricle

• Front Atrium, Back Atrium, Front Ventricle, Back Ventricle

• Right Atrium, Right Ventricle, Left Atrium, Left Ventricle

What is the significance of the sinoatrial node and the atrioventricular node in heart function?

• They regulate the heart's rhythm and coordinate the timing of contractions between the atria and ventricles.

• They are involved in the digestion of food in the heart

• They control the release of hormones in the heart

• They are responsible for regulating blood pressure in the heart
