Q

Pericardium

A

Membrane that separates the heart from other mediastinal structures

Q

Pulmonary arteries

A

One of two branches that divides off from the pulmonary trunk trunk and leads to smaller arterioles and eventually to pulmonary capillaries

Q

Pulmonary trunk

A

Large arterial vessel that carries blood ejected from the right ventricle

Q

Pulse

A

Alternating expansion and recoil of an artery as blood moves through the vessel

26
Q

Purkinje fiber

A

Specialized myocardial conduction fibers that arise from the bundle branches and spread the impulse to the myocardial contraction fibers of the ventricles

Systole

A

Period of time when the heart muscle is contracting

33
Q

Tricuspid valve

A

Term used most often in clinical settings for the right atrioventricular valve

34
Q

Valve

A

A specialized structure located within the heart or vessels that ensures one-way flow of blood

35
Q

Vein

A

Blood vessels that conducts blood toward the heart

36
Q

Vena cava

A

The artery that conducts blood away form the heart and into the lungs and stuff

37
Q

Ventricle

A

One of the primary pumping chambers of the heart located in the lower portion

38
Q

Visceral pericardium

A

Layer of connective tissue that is located in the outermost layer

39
Q

Bradycardia

A

Abnormally low heart rate

40
Q

Congestive heart failure

A

A chronic condition in which the heart doesn’t pump blood as well as it should.

41
Q

Endocarditis

A

An infection of the heart’s inner lining, usually involving the heart valves.

42
Q

Fibrillation

A

An irregular, often rapid heart rate that commonly causes poor blood flow.

43
Q

Heart palpitation

A

A feeling that your heart is beating too hard or too fast, skipping a beat, or fluttering.

44
Q

Hypertension

A

A condition in which the force of the blood against the artery walls is too high.

45
Q

Hypertrophic cardiomyopathy

A

A condition in which the heart muscle becomes abnormally thick.

46
Q

Hypotension

A

Abnormally low blood pressure

47
Q

Mitral valve prolapse

A

Improper closure of the valve between the heart’s upper and lower left chambers.

Q

Myocardial infarction

A

A blockage of blood flow to the heart muscle.

49
Q

Myocarditis

A

Inflammation of the middle layer of the heart wall.

Q

Pulmonary heart disease

A

the medical term for disease affecting the blood vessels leading to or from the lungs. Most forms of pulmonary vascular disease cause shortness

51
Q

Tachycardia

A

Abnormally high heart rate

52
Q

Serous pericardium

A

functions to lubricate the heart with pericardial fluid, which is stored in the space between the parietal and visceral layers.
