Cardiovascular System Overview Quiz

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

The heart pumps blood to deliver oxygen and nutrients to the body.

The cardiovascular system primarily transports blood, nutrients, oxygen, and waste products, but it does not produce hormones.

Lymphocytes are a type of white blood cell involved in the immune system, not blood vessels.

Hemoglobin, a protein in red blood cells, carries oxygen from the lungs to the rest of the body.

Arteries carry oxygen-rich blood away from the heart to the body.

The aorta is the main artery that carries oxygenated blood from the heart to the body.

Systole is the phase when the heart muscle contracts, pumping blood.

High blood pressure increases the risk of cardiovascular problems like heart attacks and strokes.

Capillaries are the smallest blood vessels where oxygen and nutrients are exchanged for waste products.

Persistent coughing can be a symptom of heart failure, indicating fluid buildup in the lungs.

The left ventricle pumps oxygenated blood to the body through the aorta.

Arrhythmia is an irregular heartbeat, which can be too fast or too slow.

Diastolic pressure is the pressure in the arteries when the heart rests between beats.

A myocardial infarction occurs when blood flow to part of the heart muscle is blocked, causing damage or death to the tissue.

Atherosclerosis is the buildup of plaque in the arteries, restricting blood flow.

Platelets are cell fragments that help form blood clots to stop bleeding.
