HEALTH PROBLEMS, SPECIALIZED

CELLS AND THE SYSTEMS.

What is it?

How does it affect the systems?

What happens to the cells?

A stroke or brain attack

that happens when an artery is blocked

by a clot or when blood vessels break

which causes blood to flow to an area in

the brain. When this happens brain cells

die within minutes.

An Ischemic stroke also known

as cerebral infarction happens when the

blood is flowing through the arteries

which is blocked. There are three kinds

of Ischemic stroke:

A Thrombotic stroke is when

two or more arteries have been

blocked by thrombosis. Thrombosis is

the scientific process of unhealthy

blood vessels build up of

arthrosclerosis. Our body reacts to this

by building up a clot.

An Embolic stroke is when parts

of the original atherosclerosis clot in

another part of the body (usually in the

heart) breaks off and travels to brain

through blood stream. That clot then travels through

blood vessels small enough to block the passage. It stays

there, blocking the blood vessel and leading it to stroke

A Thromboembolic stroke is

when parts of the atherosclerosis

clot in the brain breaks off and

travels to different arteries and block

them.

A Hemorrhagic stroke happens

when an aneurysm in the artery break

and blood flow into the brain. There are

two types;

A Cerebral Hemorrhage is when blood vessel in the brain

break filling the surrounding tissues with blood while Subarachnoid

Hemorrhage is when broken blood vessel on the brain surface filling

the space between the brain and skull with blood.

• Since stroke deals with brain, the only organ system it

does affect would be the nervous system. Nerve cells will

be deoxygenated and will die. Nerve cells stops working

which messes up that specific area of the brain.

• It does not directly affect the circulatory system, when

the arteries are blocked the blood will not reach that area

resulting in the damage. The red blood cells will not be

able to take any carbon dioxide and waste from the nerve

cells while giving out oxygen and nutrients.

HOW THE HEALTH PROBLEMS

AFFECTS QUALITY OF LIFE?

Symptoms of the illnesses?

How they affect the daily life?

Treatments or detection?

risks

Both (men and women) a family history of stroke high blood pressure high cholesterol, smoking diabetes being overweight not exercising Family history TIA Atrial Fibrillation

women Birth control pills Pregnancy Hormone replacement

therapy High triglyceride (blood fat) Migraine sufferer

symptoms

Both (men and women) Hardening the arteries by

atherosclerosis, high blood pressure, diabetes.

Blood clotting disorders Dizziness, trouble walking, loss of

balance and coordination Speech problems numbness,

weakness, or paralysis on one side of the body

Blurred, blackened, or double vision

Sudden severe headache, aneurysm

women Sudden face Limb pain Hiccups Nausea Chest pain Breath problems Palpitations

Treatments for ischemic stroke is where the person has to take blood clot busting such as aspirin.

Surgery where they will try to open up the arteries.

Endarterectomy: remove plaque and wide arteries

Angioplasty: balloon that widens the arteries and held open with a metallic tube.

DESCRIBE THE DIAGNOSTIC TESTS

USED TO IDENTIFY THE PROBLEM?

What are some risks?

What are some benefits?

CT Scan: Allergic

reaction to the dye

and radiation.

Ultrasound: Detect

blood flow through

arteries and never

exposed to radiation

MRI: Can show any

damaged tissues, 3 – D

images of the body

CT Scan: Accurate and

detailed imagery

Ultrasound: Many

cancer will not be

detected

MRI: Claustrophobic

people and people

who have metallic

things in their body.
