Cardiovascular System and Blood Disorders Quiz

The brain is part of the nervous system, not the cardiovascular system.

Red blood cells carry oxygen from the lungs to the body tissues.

Platelets play a key role in blood clotting, helping to stop bleeding by forming clots.

Regular exercise is actually a protective factor against cardiovascular disease.

The pulmonary vein carries oxygen-rich blood from the lungs back to the heart's left atrium.

Atherosclerosis is the condition where fatty deposits, or plaque, build up inside the arteries, narrowing them and restricting blood flow.

Chest pain or discomfort is a common symptom of cardiovascular disease.

Hypertension refers to high blood pressure, a major risk factor for cardiovascular disease.

Myocardial infarction, commonly known as a heart attack, occurs when blood flow to a part of the heart is blocked for a long enough time that part of the heart muscle is damaged or dies.

Thrombocytes, also known as platelets, are not white blood cells; they are cell fragments involved in blood clotting.

Polycythemia is a disorder where the body produces too many red blood cells, leading to thickened blood and increased risk of blood clots.

The SA node, often called the heart's natural pacemaker, initiates electrical impulses that coordinate the heart's contractions.

Hemophilia is a disorder where blood doesn't clot properly due to missing or deficient clotting factors.

Anemia is a condition characterized by a lack of red blood cells or hemoglobin in the blood, leading to reduced oxygen transport to tissues.

Cold extremities are not typically associated with deep vein thrombosis; common symptoms include leg pain, swelling, and warmth.

Shortness of breath, especially during physical activity or when lying down, is a common symptom of congestive heart failure.

Leg cramping, especially during physical activity, is a common symptom of peripheral artery disease, caused by narrowed arteries limiting blood flow to the legs.
