Cardiovascular System and Vessel Characteristics Quiz

Left ventricle pumps oxygenated blood to the body.

Typically, adults have a resting heart rate of 60-70 beats per minute.

Right atrium pumps blood to the lungs for oxygenation.

Capillaries are the smallest blood vessels where oxygen and nutrient exchange occurs with body tissues.

Regular physical activity is associated with a decreased risk of cardiovascular diseases.

The main function of the sinoatrial (SA) node in the heart is to conduct electrical impulses.

Artery carries oxygenated blood away from the heart.

Coronary arteries supply oxygenated blood to the heart muscle.

Heart attack is medically termed as myocardial infarction.

Insulin is not a component of blood.

Bicuspid valve, also known as the mitral valve, separates the left atrium from the left ventricle.

The alternating expansion and contraction of the arterial wall, felt as a pulse, is termed as pulse wave.

High blood pressure is a major risk factor for cardiovascular diseases.

Endothelium in blood vessels primarily controls blood flow.

Superior vena cava carries deoxygenated blood to the right atrium from the upper body.

Buildup of fatty deposits on artery walls is termed as atherosclerosis.

Hemoglobin's function in the circulatory system is to transport oxygen.

Diastole represents the relaxation of heart chambers, allowing them to fill with blood in the cardiac cycle.
