• A. pericardium
• B. myocardium
• C. endocardium
• D. septum
• E. superior vena cava
• F. Inferior vena cava
• G. right atrium
• H. tricuspid valve
• I. Right ventricle

• J. pulmonary semilunar valve
• K. pulmonary artery
• L. pulmonary veins

• M. left atrium
• N. bicuspid or mitral valve
• O. left ventricle

• P. aortic semilunar valve
• Q. aorta

• 3. Describe what happens in the heart during
  diastole.

Atria contract and push blood into the
ventricles.
4. Describe what happens in the heart during
systole. State where each ventricle sends the
blood.
right ventricle pushes blood into pulmonary
artery so blood goes to the lungs, left ventricle
pushes blood into the aorta so blood goes to all
parts of the body.

• 5. List the parts of the conductive pathway for
  electrical impulses in the heart. List the parts
  in correct order.

( SA) node, pathways in the atria,
atrioventricular (AV) node, bundle of His, right
left bundle branches, Purkinje fibers
7
                                                
         1 The SA node sets the rate and rhythm
of your heartbeat
Conductive Pathway
8
Conductive Pathway
                                                
         2 The SA node fires an impulse. The
impulse spreads through the walls of the right
and left atria, causing them to contract. This
forces blood into the ventricles.
9
Conductive Pathway
3 The impulse travels to the AV node. Here, the
impulse slows for a moment before going on to the
ventricles.
10
Conductive Pathway
4 The impulse travels through a pathway of fibers
called the HIS-Purkinje network. This network
sends the impulse into the ventricles and causes
them to contract. This forces blood out of the
heart to the lungs and body.
11
Conductive Pathway
5 The SA node fires another impulse. The cycle
begins again.

• 6. What is arrhythmia? How is it diagnosed?

abnormal heart rhythm cardiac monitors
electrocardiogram

7. Identify the following blood vessels
arteries

• A. blood vessels that carry blood away from the
  heart
• B. Blood vessels that carry blood back to the
  heart
• C. Blood vessels that connect arterioles with
  venules.
• D. Largest artery in the body.
• E. Two largest veins in the body.
• F. Vessels that allow oxygen nutrients to pass
  through to cells.
• G. Smallest branches of arteries.
• H. Smallest branches of veins.
• I. Vessels that contain valves to prevent
  backflow of blood.
• J. Most muscular elastic blood vessels.

17
11. What gives blood its characteristic red color?

• Hemoglobin and the amount of oxygen present.

18
12. What is hemoglobin? What is its function?

• Hemoglobin is a complex protein found on the red
  blood cell and its function is to carry oxygen
  and carbon dioxide.
