Blood Vessels
Arteries
Carry blood away from the heart
Are muscular and have a pulse
Are thicker than veins or capillary http://www.doereport.com/generateexhibi

Artery
Vein
Veins
Carry blood to the heart Have thinner walls than arteries Have valves to prevent blood from
flowing backwards Must move muscles near veins to prevent
clotting http://www.doereport.com/generateexhibi

How Much Blood Do We have?
Parts of Blood and their Functions
Red Blood Cells – contain hemoglobin which attracts and helps transport oxygen
White Blood Cells – fight infection and make antibodies
Platelets – stop bleeding and seal leaks Plasma – transports nutrients, wastes
(including CO2 ), and hormones

Artery Blockage
Cardiovascular Disease
What could go wrong? Blockages Leaking Muscular failure Thickening of heart Beating problems Blood disorders
Most Common Disorders
Coronary Artery Disease (CAD) Atherosclerosis – narrowing of arteries Heart Attack – myocardial infarction Stroke Hypertension - high blood pressure Deep Vein Thrombosis (DVT) Angina Irregular heartbeat Leaky valves
Coronary Artery Disease
When an artery or arteries is partially or fully blocked stopping blood flow to the heart or other body organ
Coronary Thrombosis
Atherosclerosis
Narrowing and loss of flexibility in an artery slowing flow of blood to an organ
Artherosclerosis
Stroke
Blocking of flow of blood to the brain
Bleeding of a blood vessel in the brain
Hypertension
High Blood pressure Can damage:
Blood vessels Organs Cause plaque to become loose
Blood Disoders
Anemia Hemophilia Leukemia Sickle cell anemia Sticky Blood Blood Poisoning AIDS
Warning Signs of Heart Attack
Chest discomfort. Most heart attacks involve discomfort in the center of the chest that lasts for more than a few minutes, or goes away and comes back. The discomfort can feel like uncomfortable pressure, squeezing, fullness, or pain.
Discomfort in other areas of the upper body. Can include pain or discomfort in one or both arms, the back, neck, jaw, or stomach.
Shortness of breath. Often comes along with chest discomfort. But it also can occur before chest discomfort.
Other symptoms. May include breaking out in a cold sweat, nausea, or light-headedness.
Symptoms More Likely in Women
Indigestion or gas-like pain Dizziness, nausea or vomiting Unexplained weakness, fatigue Discomfort/pain between shoulder blades Recurring chest discomfort Sense of impending doom
