The Structure and Function of the Human Heart and Blood Vessels
True or False
 The human heart is a single pump __T or F__
 Arteries have valves __T or F__
 Although the circulatory system appears to be a tangled mess, blood flow is unidirectional __T or F__
The Circulatory System and the Heart
1. Label and colour in the parts of the circulatory system that carry oxygenated blood (in red) and
deoxygenated blood (in blue)
2. Given the following diagram of the human heart, identify the indicated structures in the space provided.
3. Draw in arrows showing the direction of blood flow in the heart above. Use blue arrows for
deoxygenated blood and red for oxygenated.
The Sequence of Blood Flow
Using the word list below, complete the following flowchart depicting blood flow through one complete loop of
circulation, beginning and ending with the left ventricle.
Word List
Pulmonary artery, tricuspid valve, arteries, aorta, aortic semilunar valve, veins, bicuspid (mitral) valve, right
atrium, capillaries, right ventricle, pulmonary vein, pulmonary semilunar valve, lungs, vena cava, left atrium
Correct order: left atrium,
The Circulatory System in Health and Disease
True or False
 Heart disease is associated with being over the age of 50. __T or F__
 A “sign” is something that is visible, while a “symptom” is something that must be described by the
person who is ill. __T or F__
 The heart muscle is irreplaceable once it is diseased and damaged. __T or F__
 Smoking is one of the leading causes of heart disease. __T or F__
Heart Disease

you can control. (e.g.; Age, lack of exercise*, smoking*, high blood pressure*, genetics, diabetes*, high
cholesterol*, family history of heart disease.)
2. Complete the following chart using the items from the above brainstorm.
Causes That Are Preventable
Causes That Are Not Preventable
3. Suggest some lifestyle changes that might help to promote health and reduce one’s risk of heart disease.
4.
