Cardiovascular System Terminology Quiz

Arteries carry oxygenated blood away from the heart to various parts of the body.

The SA node conducts electrical impulses, regulating the heart's rhythm and coordinating atrial contractions.

Atherosclerosis is the medical term for the accumulation of fatty deposits on artery walls, leading to reduced blood flow.

The primary function of the cardiovascular system is to transport oxygen, nutrients, and waste products throughout the body.

The pericardium provides protection and support for the heart, enclosing it in a sac.

Atria receive blood from the body and pump it to the ventricles for further circulation.

Systole is the phase when the heart contracts to pump blood.

Systolic pressure is the maximum pressure exerted by the blood against artery walls during heart contraction.

The mitral valve prevents backflow of blood from the left ventricle to the left atrium during heart contractions.

The left ventricle pumps oxygenated blood to the body, providing oxygen and nutrients to various tissues.

Heart rate is the number of heartbeats per minute, indicating the heart's rhythm and efficiency.

A heart attack is medically termed as myocardial infarction, involving the damage or death of heart muscle.

The renal vein is not a major blood vessel connected to the heart; it carries blood from the kidneys back to the heart.

High blood pressure is a major risk factor for cardiovascular disease, leading to increased strain on the heart and arteries.

Pulmonary circulation refers to the circulation of blood between the heart and lungs for oxygenation.

Veins carry deoxygenated blood from the body back to the heart for oxygenation.

Arrhythmia refers to an irregular heartbeat, disrupting the normal heart rhythm.
