CIRCULATORYSYSTEM

serves to move blood to a site or sites where it can be oxygenated, and where wastes can be disposed.

The Circulatory System is the main transportation and cooling system for the body.

The circulatory system is how good and bad materials travel through our bodies.

The Circulatory System is responsible for transporting materials throughout the entire body. It transports nutrients, water, and oxygen to your billions of body cells and carries away wastes such as carbon dioxide that body cells produce.

The HEARTH

The BLOOD

The Blood Vessels

three types of blood vessels:

Arteries ( red )Veins ( blue )Capillaries

Flow of the blood

Blood flow is the continuous running of blood in the cardiovascular system

Tracing the flow of blood through the heart isn't as simple as it may seem. The heart is a complex organ, using four chambers, four valves and multiple blood vessels to provide blood to the body. The flow through the heart is equally complex, with blood moving through the heart, then the lungs, before returning again to the heart.

AILMENTS OF

CIRCULATORY SYSTEM

STROKE

What Is a Stroke?Stroke is a medical emergency and the third leading cause of death in

the U.S. It occurs when a blood vessel in the brain bursts or, more

commonly, when a blockage develops. Without treatment, cells in

the brain quickly begin to die. The result can be serious disability or

death. If a loved one is having stroke symptoms, seek emergency medical

attention without delay.

Stroke SymptomsSigns of a stroke may

include:Sudden numbness or

weakness of the body, especially on one side.Sudden vision changes in one or both eyes, or difficulty swallowing.

Sudden, severe headache with unknown

cause.Sudden problems with dizziness, walking, or

balance

Stroke Test: Talk, Wave, Smile

The F.A.S.T. test helps spot

symptoms. It stands for:

Face. Ask for a smile. Does one

side droop?Arms. When raised, does one side drift

down?Speech. Can the person repeat a

simple sentence? Does he or she

have trouble or slur words

Stroke: Time = Brain Damage

Every second counts when seeking treatment

for a stroke. When deprived of oxygen,

brain cells begin dying within minutes. There are clot-busting drugs

that can curb brain damage, but they have to be used within three

hours of the initial stroke symptoms. Once brain

tissue has died, the body parts controlled by that

area won't work properly. This is why stroke is a top cause of long-term

disability.

What Is Heart Disease?The topic of heart disease usually centers on heart attacks but there are many other problems that can compromise heart functions, injure the heart tissues, or cause heart disease. Most of the major problems include coronary artery disease, heart failure, arrhythmias, and cardiomyopathy. The following slides will present these heart problems and their warning signs

What Is a Heart Attack?A heart attack occurs

when a coronary artery becomes blocked (usually in a coronary artery by a blood clot) resulting in

loss of the blood supply to an area of heart tissue. Loss of the blood supply can quickly damage and kill heart tissue; quick

treatments in the emergency department

and/or the catheterization suite have reduced

deaths from heart attacks in recent years but still

more than a million

Symptoms of a Heart Attack

Warning signs of a heart attack include

the following:Chest pain

Pain that may spread to the back, arms, neck,

and jawShortness of breathNausea, vomitingRapid or irregular

heartbeats

Inside a Heart AttackPlaque in coronary (and other) arteries

maybe hard or firm on the outside but soft, mushy, and sticky on the inside. If the hard shell-like area cracks

open, then blood components exposed

to the sticky areas collect and can form a blood clot and quickly block most or all of the blood flow through the artery. The heart tissue downstream from the clot then suffers from

lack of blood and becomes damaged or

dies.

Call 911 When Symptoms Occur

If you or an individual develop symptoms of a heart attack, do not delay getting medical help. Call 911. Do not drive yourself or others to a hospital as 911 emergency medical services (EMS) personnel can begin

basic treatment immediately. Delaying care can result in increased heart damage or

death

Atherosclerosis is a disease of the arteries in which fatty material

is deposited in the vessel wall, resulting

in narrowing and eventual impairment

of blood flow. Severely restricted blood flow in the

arteries to the heart muscle leads to

symptoms such as chest pain.

Atherosclerosis shows no symptoms until a complication occurs.
