Human Cardiovascular System Terminology Quiz

Right atrium receives deoxygenated blood from the body via the superior and inferior vena cava.

Pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart.

The aorta distributes oxygen-rich blood to the body's tissues through its branches.

Kidneys are part of the renal system, not the cardiovascular system.

Veins return deoxygenated blood from the body's tissues back to the heart.

The aorta carries oxygen-rich blood from the left ventricle of the heart to the body's tissues.

Coronary circulation ensures the heart muscle receives oxygen and nutrients for proper function.

The lub sound is caused by the closing of the atrioventricular valves (mitral and tricuspid) during ventricular systole.

Diastole is the phase when the heart muscle relaxes, allowing the chambers to fill with blood.

Myocardial infarction occurs when blood flow to part of the heart muscle is blocked, leading to tissue damage.

Arrhythmia refers to abnormal heart rhythms, which can be rapid, irregular, or both.

Hypertension is a condition where blood pressure in the arteries is persistently elevated.

Regular exercise is beneficial for cardiovascular health, not a risk factor.

Stroke volume represents the amount of blood ejected from the left ventricle per heartbeat.

The aorta is the largest artery, originating from the left ventricle of the heart.

Atherosclerosis is a condition where plaque buildup in arteries restricts blood flow.

Hematopoiesis is the process of forming blood cells, including red blood cells, white blood cells, and platelets.
