2. What is the organ?
The heart is one of the main organs in the body. The heart is made up of many strong muscles that squeeze and
relax to pump blood to all parts of the body. The blood flowing contains oxygen, food, vitamins, and minerals your
body needs to function. This pump happens about 70-90 times per minute. The heart is made up of 4 parts:the
left ventricle, the right ventricle which are both at the bottom part of the heart, and the left atrium and the right
atrium are located at the top.

3. Where is the
Heart Located?
The heart is located behind your
ribs on the left side of your body next to your
sternum.

4. The various functions of each
part of the heart :
1. Aorta the body's largest artery. Takes oxygenated blood from the
left ventricle to the body.
2. Pulmonary Artery carries deoxygenated blood from the right
ventricle to the lungs.
3. Oxygenated blood carrying oxygen
4. Deoxygenated blood carrying little or oxygen
5. Right Atrium Receives deoxygenated blood from the body
6. Pulmonary Vein Takes oxygenated blood from the lungs to the
left atrium
7. Left Ventricle Pumps oxygenated blood into the aorta
8. Right Ventricle pumps deoxygenated blood into the pulmonary
artery
9. Coronary Vessels supply the heart muscle with its blood supply
10. Arteries carry blood away from the heart
11. Veins carry blood towards the heart
12. Bicuspid Valve valve between the left atrium and the left
ventricle.
13. Tricuspid Valve valve between the right atrium an the right
ventricle.
14. Vena Cava the largest vein in the body, it carries blood from the
body back to the heart.

5. Diseases associated with the heart:
1. Hypertensive heart disease
2. Cerebrovascular disease
3. Ischemic heart disease
4. Rheumatic heart disease
5. Inflammatory heart disease

6. Cerebrovascular Disease

7. Causes :
Is when a build up of a thick waxy substance in
the vessel that narrows or blocks the blood flow
in the arteries That is caused by high cholesterol
levels.

8. Symptoms:
headache that is severe and sudden
•confusion
•difficulty communicating
•loss of half of vision
•loss of balance
•loss of consciousness

9. Diagnoses:
● computes tomography
● magnetic resonance imaging (MRI)
● cerebral angiography- identify responsible
blood vessel
● electrocardiogram (ECG)-underlying heart
conditions
● echocardiogranm- blood clot from heart
● carotid duplex- carotid artery stenosis.

10. Treatment:
In the case of a minor stroke, a medication called
tissue plasminogen activator (tPA) may be given
which breaks the clot.
If it is a larger stroke a surgery may be required.
