Principles of Health Science – Cardiovascular System Notes
Station 1
Using the textbook, Diversified Health Occupations (pp. 142-143), fill in the blanks.
1. The circulatory system, also known as the cardiovascular system, is often referred to as the ________________
system of the body. It consists of the heart, ________________________________, and blood.
2. The heart, often called the _______________________ of the body, is the size of a closed fist.
3. Three layers of tissue form the heart. The __________________________ lines the inside of the heart. The
thickest layer is the myocardium, the muscular _________________________layer. The
_________________________ covers the outside of the heart.
4. The septum is a muscular wall that __________________________ the heart into right and left sides.
5. The heart is divided into four parts or ____________________________________.
6. The two ______________________chambers are called atria and the two __________________________
chambers are called ventricles.
7. The right atrium receives blood as it _______________________ from the body cells.
8. The right ____________________________ receives blood from the right atrium.
9. The right ventricle pumps blood into the pulmonary artery, which carries blood to the ___________________
for oxygenation.
10. The left _________________________ receives oxygenated blood from the lungs.
11. The left ventricle receives blood from the left atrium and pumps the blood into the _______________________
for transport to the body cells.
12. _________________________valves in the chambers of the heart keep the blood flowing in the right direction.
13. The tricuspid valve is located between the ______________________atrium and the right ventricle.
14. The pulmonary valve is located between the right ventricle and the ________________________ artery.
15. The ______________________valve is located between the left atrium and left ventricle.
16. The aortic valve is located ____________________________ the left ventricle and the aorta.
17. The right and left sides of the heart work together in a ____________________________manner.
18. The cycle consists of a brief period of _______________________ called diastole.
19. Diastole is followed by __________________________, a period of ventricular contraction.
20. Systole is the top number in a blood pressure reading ( ex. 130 in 130/80). Diastole is the bottom number.

Station 3
View the powerpoint “Cardiovascular Diseases” and fill in the blank.
Diseases
1. Coronary Artery Disease (CAD)- narrowing of the coronary ______________.
2. Atheroclerosis - (ather/o = plaque + -sclerosis = hardening) hardening and narrowing of arteries by build-up of
_____________________________ plaque.
3. Angina Pectoris - Spasm of chest pain due to a ______________________ in blood flow to the myocardium.
4. Myocardial Infarction - Also known as __________________________ or “MI”; blockage of a coronary artery
resulting in death of the surrounding tissue.
5. Arrhythmias - abnormal rhythm of the _____________________________.
6. Bradycardia - (brady- = slow + cardi- = heart + -ia = abnormal condition) - slow heartbeat, less than _____ beats
per minute.
7. Tachycardia - (tachy- = fast) - fast heartbeat, greater than ___________ beats per minute.
8. Fibrillation - rapid, ineffective contractions of the heart.
9. ____________________fibrillation - irregular contraction of the ventricle, will result in death unless corrected
quickly.
10. Hypertension - (high blood pressure) - blood pressure ___________________normal limits (normal 130/90)
Diagnostic Procedures
11. Angiography - (angi/o = blood vessels + -graphy = process of recording) - x-ray study of blood _______________.
12. Echocardiography - (ech/o = sound) ultrasound of the structures and _____________________ of heart.
Medications
13. _____________________________ - (anti- = against) - used to lower blood ___________________________
14. Nitroglycerine - Used to dilate blood vessels and relieve_______________________ of angina.
15. ________________________________ - slows blood clotting and prevents ____________clots from forming.
Methods to clear Blocked Arteries
16. PTCA - Percutaneous Transluminal Coronary Angioplasty a ____________________ is inserted during cardiac
cardiac catheterization and inflated inside the artery, this opens the plaque in the vessel so more
__________________ can flow through, balloon is deflated and removed.
17. Coronary Artery Bypass Graft (CABG) - a portion of a vein is removed from the ______________and attached to
the blocked _______________________ in the heart, this causes blood flow to go around (bypass) the blockage
and improve blood flow to the heart.
Other Treatments
18. Defibrillation - Use of electrical shock to restore heart’s normal ________________________.
19. Cardiopulmonary Resuscitation (CPR) - emergency procedure for life support, consists of compressions and
breaths.
Station 4
Fill in the blanks on the “Pattern of Circulation” sheet. Refer to p. 144 in Diversified Health Occupations.
Using a blue crayon or marker, circle those words that transport deoxygenated (oxygen-poor) blood.
Using a red crayon or marker, circle those words that transport oxygenated (oxygen –rich) blood.
Study the pattern of circulation and quiz each other. (ex. After the right atrium, the blood travels through the________)
