Q

Circulatory system

A

Also known as the cardiovascular system has 3 major components the heart the blood vessels and the blood

20
Q

Congestive heart failure

A

Medical diagnosis that refers to the condition in which there is a buildup of fluid in the body resulting from the pump failure of the heart

21
Q

Coronary arteries

A

Are the first two arteries to originate off the aorta and are the same arteries that are associated with many cardiac emergencies

22
Q

Coronary artery disease

A

Narrowing and hardening of the coronary attires is the most common type of heart disease and is responsible for more then 385k deaths each year

23
Q

Cor pulmonale

A

Right sided heart failure

24
Q

Depolarization

A

The first in which electrical charges of the heart muscle change from negative to positive and cause the heart muscle to contract

Q

Dysrhythmia

A

Cardiac rhythm abnormalities

26
Q

Fibrin

A

Protein strands that form a mesh that strengthens a clot

Levine sign

A

Fist clenched over the center of their chest

31
Q

Myocardial ischemia

A

State in which there is inadequate delivery of oxygen to the heart muscle

32
Q

Nitroglycerin

A

Potent vasodilator. Works in seconds to relax the muscles of the blood vessel walls

33
Q

Perfusion

A

The delivery of oxygen and nutrients from the blood through the thin capillary walls into the cells and the removal of carbon dioxide and other wastes

Q

Plaque

A

Fatty deposit

A

The restoration of blood to an area of tissue that was ischemic from low blood flow or occlusion of a vessel

38
Q

Repolarization

A

Second component in which the electrical charges of the heart muscle return to a resting negative charge and cause relaxation of the heart muscle

39
Q

Thrombin

A

Protein responsible for activating the formation of the clot

40
Q

Thrombus

A

Clot that is formed

41
Q

Unstable angina

A

Usually indicates angina discomfort that is prolonged and worsening or that occurs without exertion and when the patient is at rest

42
Q

Vein

A

Carry deoxygenated blood from the capillaries where the blood has picked up carbon dioxide and other waste products given off by the cells

43

The two bottom chambers of the heart

45
Q

Venule

A

That circulate blood throughout the body
