1. Ch 5 The Cardiovascular System

2. Overview Heart:cardi/o> Pumps blood into the arteries.
Arteries: arteri/o> Transports blood away to all body parts (thick).
Capillaries: capill/o> Exchanges nutrients and waste products with cells.
Veins: phleb/o, ven/o> Returns blood to the heart (thin).
Blood: hem/o, hemat/o> Brings oxygen and nutrients to all cells and carries away waste. Plays several important roles in the immune and endocrine systems.

4. Arrhythmias:
Cardiac arrhythmia- is an irregularity or the loss of normal rhythm of the heartbeat.
Bradycardia- is an abnormally slow heartbeat (less than 60 beats per minute).
Palpitation- is a pounding of a racing heart with or without irregularity in rhythm. This is associated with certain heart disorders or a panic attack.
Tachycardia- is an abnormal fast heartbeat (greater than 100 beats per minute).

5. Cholesterol
Cholesterol- consists of lipids (fatty substances) that travel in the blood in packages called lipoproteins.
Low-density lipoproteins (LDL)- bad cholesterol that when in excess clogs the arteries. Your number should be less than 200.
High-density lipoproteins- good cholesterol because it carries unneeded cholesterol back to the liver for processing and does not contribute to plaque build up. Your number should be more than 35.
Triglycerides- are combinations of fatty acids attached to glycerol that are also found normally in the blood in limited quantities. Your number should be less than 110.
Hyperlipidemia- is a general term for elevated plasma concentrations of cholesterol, triglycerides, and lipoproteins. The levels of each of these substances can be measured by a blood test.

7. Blood Types As Donors and Recipients:

8. Words
Anemia> a disorder characterized by lower than normal levels of red blood cells in the blood
Aorta> the main trunk of the arterial system and begins from the left ventricle of the heart
Arterioles> the smaller thinner branches of the arteries, carries blood to the capillaries
Cardiologist> A specialist in diagnosing and treating abnormalities, diseases, and disorders of the heart
Coronary Artery Disease> atherosclerosis of the coronary arteries that may cause a heart attack
Erythrocytes> red blood cells
Bradycardia> an abnormally slow heartbeat
Phlebitis> inflammation of veins
Superior vena cava> brings blood from the upper portion of the body
Thrombosis> an abnormal condition in which a blood clot develops within a blood vessel
