The heart, blood vessels (arteries, veins, capillaries), and blood, working together to circulate blood throughout the body.

The heart has four chambers: two atria (receiving chambers) and two ventricles (pumping chambers).

Tricuspid, pulmonary semilunar, mitral/bicuspid, and aortic semilunar valves control blood flow direction and prevent backflow in the heart.

A system of electrical signals that coordinate heart muscle contractions.

The sinoatrial node (SA node) is the heart's natural pacemaker, initiating the heartbeat.

A recording of the electrical activity of the heart, displaying the heartbeat's electrical waves.

Blood vessels supplying oxygenated blood to the heart muscle (myocardium).

Carry oxygenated blood away from the heart to the body.

The largest blood vessel, the main artery transporting blood.

Major arteries providing blood to the head.

The smallest blood vessels, one cell thick, connecting arterioles to venules.

The smallest veins that collect blood from capillaries to form larger veins.

Pressure exerted on artery walls when the heart contracts.

Pressure exerted on artery walls when the heart relaxes.

Red blood cells that carry oxygen.

White blood cells that fight infection.

WBCs engulf and destroy pathogens.

Least common WBC, cause allergic symptoms.

Destroy parasites, involved in allergies.

Identify and fight germs, produce antibodies.

Form in marrow, lymph, spleen, phagocytic.

Smallest blood cells, clot blood.

Structural heart problems at birth.

Narrowing of coronary arteries, poor blood supply.

Chest pain that occurs during exertion (physical activity).

Chest pain that occurs during exertion or rest, and is a serious warning sign.

A heart attack; a blockage of coronary arteries, causing oxygen deprivation to the heart muscle.

Inability of the heart to pump all received blood efficiently.

Abnormal sound heard in the heart or blood vessels.

Irregular heartbeat rhythm.

Heart abruptly stops beating.

Inflammation of blood vessels.

A benign tumor made of newly formed blood vessels

A weakened or ballooned artery wall

Hardening of the arteries

A blood clot attached to a vessel wall

Blocking of a blood vessel by a foreign object

Low white blood cell count

High red blood cell count

Low platelet count

A condition where the body lacks enough iron to create hemoglobin, a protein that carries oxygen in red blood cells.

A genetic disorder causing abnormal hemoglobin, leading to misshapen red blood cells that interfere with blood flow.

An inherited blood disorder resulting in reduced hemoglobin and fewer red blood cells than normal.

High blood pressure, where blood pressure in arteries is elevated to a potentially harmful level.

A radiographic study of blood vessels after injecting a contrast medium to visualize the vessels.

A non-invasive process to record the electrical activity of the heart muscle.

A procedure using a balloon to widen blocked arteries, then a stent is usually placed to keep the artery open.

A surgery that repairs blocked coronary arteries by using a transplanted blood vessel to improve blood flow to the heart.
