4. Write a paragraph describing the pathway of blood through the body.
In your description be sure to use the following terms AND UNDERLINE THEM:
Right atrium Body
Right ventricle Lungs
Left atrium Pulmonary Artery
Left ventricle Pulmonary Vein
Aorta Oxygen Poor Blood
Vena Cava Oxygen Rich Blood

5. The Pathway of Blood
First the oxygen poor blood moves into the right atrium through the vena cava. Next, the oxygen poor blood moves into the right ventricle. The blood then leaves the heart though the pulmonary artery and goes to the lungs to pick up oxygen.
The oxygen rich blood then comes back to the heart through the pulmonary veins and flows into the left atrium. The blood next moves to the left ventricle and then goes out to the body cells through the aorta.
The oxygen rich blood delivers oxygen and nutrients to all of the cells. After, the oxygen poor blood will flow back to the heart through veins, back to the Vena Cava and the process begins again.

3) An irregular heartbeat
4) Feeling pauses between heartbeats
Treatment: medicine, procedures,
and surgery (pacemakers)
What is atrial fribillation?
Most common type of A-Fib. Involves a very fast/irregular contraction of atria.
Normal Heart Rhythm
Arrhythmia

10. Stroke
Description: A stroke occurs if the flow of oxygen-rich blood to a portion of the brain is blocked.
What causes an Ischemic Stroke?: Artery that supplies oxygen-rich blood to the brain becomes blocked. *Most common type
What causes Hemorrhagic stroke? Artery in the brain leaks blood or bursts open
Symptoms:
numb on one side 3) confusion
slurred speech 4) sudden weakness
5) Severe Headache
Treatment: Get to a hospital immediately!
