Circulatory System
Heart Attack and Stroke
Brendan Weibel, Jarrett Bachelor, & Jesse Rodriguez

2. Circulatory System Arteries vs. Veins? What are Capillaries?
The Circulatory System is the system in the body that pumps blood throughout the body through Veins and Arteries
Arteries vs. Veins?
Arteries carry oxygen-rich blood
Veins carry oxygen-poor blood
What are Capillaries?
Capillaries are tiny blood vessels that transfer oxygen-poor blood from Arteries to Veins

3. Parts of the Heart Atriums: Ventricles:
Force blood from veins and arteries into Ventricles
Ventricles:
Force blood into:
Pulmonary artery if oxygen-poor (Right Ventricle
Aorta if oxygen-rick (left Ventricle)

4. Blood Vessel Contents:
Red Blood Cells:
Carries oxygen throughout the body and CO2 back to the lungs
White Blood Cells:
Produce antibodies and fight bacteria throughout the body
Platelets:
Stops bleeding and helps to form scab for cuts
Plasma:
Maintains blood pressure and helps blood clot

5. Heart Attack What is a heart attack? What are the causes?
-The occurrence where the heart slows down or stops
What are the causes?
-The Coronary artery becomes blocked, stopping blood flow to the heart
Prevalence of a heart attack
-High blood pressure, high blood cholesterol, and Diabetes
-Men at the age of 45 and women at the age of 55 are more susceptible

6. Heart Attack Continued
Symptoms Include:
-Pain around the center of chest or arm
-Nausea, lightheadedness, or breaking out in a cold sweat
-Shortness of breath
Treatment:
Drugs- Aspirin, Thrombolytics, Antiplatelet Agents, Pain Relievers, and Nitroglycerin, Beta Blockers, and ACE inhibitors
Surgery- Coronary artery bypass surgery and Coronary angioplasty

7. What systems are affected?
Stroke
What is a stroke?
A stroke occurs when a blood
vessel in the brain is blocked (Ischemic)
or bursts (Hemorrhagic)
What systems are affected?
The circulatory system is affected during
a stroke
Prevalence of a stroke?
A stroke is much more likely to occur if
the person has had a stroke previously

8. Stroke Continued What is the cause of a stroke? Signs and symptoms?
Who is affected?
Chances of a stroke are increased for the elderly, women, African Americans, Native Americans, Alaskan Natives, and generally anyone who is unhealthy.
Ischemic Stroke
Hemorrhagic Stroke
Symptoms
Usually plaque buildup (Atherosclerosis) in the arteries.
Bleeding in or around the brain.
Trouble speaking, vision change, confusion, numbness, and loss of movement.

9. Stroke Continued What prevention or treatment is available?
Control risk factors (high blood pressure, high cholesterol, smoking, etc.)
Treat medical conditions that can lead to a stroke
If diagnosed soon enough, medicine can stabilize the vital systems
Important Facts
Stroke kills almost 130,000 Americans each year
Every year, more than 795,000 people in the United States have a stroke
About 87% of all strokes are ischemic strokes, when blood flow to the brain is blocked
