Human Physiology and Biomedical Engineering in Cardiovascular Health Quiz

Left atrium receives oxygenated blood from the lungs.

The average resting heart rate for adults is 70-80 beats per minute.

Assisting in immune response is not a function of the cardiovascular system.

Sudden chest pain or discomfort is a symptom of a heart attack.

Gender is not a risk factor for hypertension.

Neutrophils are not a component of blood.

Atria and ventricles are the upper and lower chambers of the heart.

Arteries carry oxygenated blood away from the heart.

Cardiac output refers to the volume of blood pumped by each ventricle per minute.

The SA node is responsible for the conduction of electrical signals in the heart.

Platelets are responsible for clotting.

The inferior vena cava carries deoxygenated blood from the body to the heart.

The SA node is also known as the pacemaker of the heart.

Bradycardia refers to the abnormal heart rhythm that is too slow.

Chemotaxis is the process by which white blood cells move to sites of tissue damage or infection.

Epinephrine is released in response to stress and increases heart rate.

Atrial fibrillation is characterized by a rapid and irregular heart rhythm.

The correct pathway of blood flow through the heart is from the right atrium to the right ventricle, then to the left atrium and finally to the left ventricle.

Regular exercise is not a risk factor for cardiovascular disease.

The mitral valve prevents backflow of blood into the left atrium.

Gas exchange occurs in the capillaries.

Myocardial infarction refers to the blockage of blood flow to a part of the heart muscle, leading to tissue damage.

Atherosclerosis is characterized by the accumulation of fatty deposits in the inner lining of arteries.

Stroke refers to the condition where blood flow to a part of the brain is blocked.

Diastolic blood pressure measures the force exerted by blood against the walls of arteries when the heart is at rest.
