Cardiovascular System Quiz: Structure of the Heart

What are the four chambers of the heart?

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

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

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

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

Describe the function of the atria and ventricles in the heart.

• The atria pump blood out to the body and lungs

• The atria and ventricles are not involved in blood circulation

• The ventricles receive blood from the body and lungs

• The atria receive blood from the body and lungs, while the ventricles pump blood out to the body and lungs.

Explain the role of the septum in the heart.

• It produces red blood cells.

• It regulates blood pressure in the heart.

• It separates the left and right sides of the heart.

• It helps in the digestion of food in the heart.

What are the main blood vessels connected to the heart?

• aorta, pulmonary artery, superior vena cava, and inferior vena cava

• coronary artery, jugular vein, popliteal artery, brachial artery

• pulmonary artery, aorta, renal vein, iliac artery

• pulmonary vein, carotid artery, femoral artery, renal artery

Discuss the function of the heart valves.

• To produce hormones

• To regulate body temperature

• To aid in digestion

• To ensure the unidirectional flow of blood through the heart chambers.

Explain the structure and function of the pericardium.

• The pericardium is a triple-walled sac that surrounds the liver and consists of the hepatic pericardium.

• The pericardium is a single-layered sac that surrounds the lungs and consists of the pleural pericardium.

• The pericardium is a fluid-filled sac that surrounds the stomach and consists of the gastric pericardium.

• The pericardium is a double-walled sac that surrounds the heart and consists of two layers: the fibrous pericardium and the serous pericardium.

Describe the pathway of blood flow through the heart.

• Right atrium, tricuspid valve, right ventricle, pulmonary valve, pulmonary artery, lungs, pulmonary veins, left atrium, mitral valve, left ventricle, aortic valve, aorta

• Left atrium, tricuspid valve, right ventricle, pulmonary valve, pulmonary artery, lungs, pulmonary veins, right atrium, mitral valve, left ventricle, aortic valve, aorta

• Pulmonary artery, right ventricle, tricuspid valve, right atrium, pulmonary valve, lungs, pulmonary veins, left atrium, mitral valve, left ventricle, aortic valve, aorta

• Right atrium, mitral valve, left ventricle, aortic valve, aorta, left atrium, tricuspid valve, right ventricle, pulmonary valve, pulmonary artery, lungs, pulmonary veins

What is the significance of the coronary arteries in the heart?

• They supply oxygenated blood to the heart muscle.

• They are responsible for regulating the body temperature.

• They have no significance in the heart.

• They supply deoxygenated blood to the heart muscle.

Discuss the differences between the right and left side of the heart.

• The right side receives deoxygenated blood from the body and pumps it to the lungs, while the left side receives oxygenated blood from the lungs and pumps it to the rest of the body.

• The left side receives deoxygenated blood from the lungs and pumps it to the rest of the body

• The right side receives oxygenated blood from the lungs and pumps it to the rest of the body

• The right side receives oxygenated blood from the body and pumps it to the lungs

Explain the concept of cardiac cycle and its phases.

• The cardiac cycle consists of systole (contraction) and diastole (relaxation) phases.

• The cardiac cycle consists of expansion and contraction phases.

• The cardiac cycle consists of digestion and absorption phases.

• The cardiac cycle consists of inhalation and exhalation phases.
