BI 102 Lab Worksheet: Cardiovascular Name ___________________________ Section _______
ACTIVITY I: Anatomy of the Heart
Using the available human heart models, write the number on the model beside each appropriate structure listed below:
_____ Aorta/aortic arch
_____ Aortic semilunar valve
_____ Inferior vena cava
_____ Left atrium
_____ Left pulmonary artery
_____ Left pulmonary veins
_____ Left ventricle
_____ Biscuspid (mitral/left AV) valve
_____ Pulmonary semilunar valve
_____ Pulmonary trunk
_____ Right atrium
_____ Right pulmonary artery
_____ Right pulmonary veins
_____ Right ventricle
_____ Superior vena cava
_____ Tricuspid (right AV) valve
ACTIVITY II: Anatomy of Blood Vessels
Match the descriptions below to the correct blood vessels.
| _____ Blood vessels from heart to the neck and head | A. aorta |
| _____ Blood vessels to heart from the neck and head | B. brachial arteries |
| _____ Blood vessels from heart to the lungs for oxygenation | C. carotid arteries |
| _____ Blood vessels to heart from the lungs | D. inferior vena cava |
| _____ Blood vessel to heart from the head, arms, & upper body | E. pulmonary veins |
| _____ Blood vessel to heart from the lower/middle body | F. pulmonary arteries |
| _____ Largest artery in body from heart to many body regions | G. renal arteries |
| _____ Blood vessels from heart to the upper arm; blood pressure is taken here | H. renal veins |
| _____ Blood vessels from heart to the kidneys | I. superior vena cava |
| _____ Blood vessels to heart from the kidneys | J. jugular veins |
ACTIVITY III: Pulmonary and Systemic Circulation
In the diagram, label the left atrium (LA), right atrium (RA), left ventricle (LV), right ventricle (RV), aorta (A), superior vena cava (SVC), inferior vena cava (IVC), pulmonary trunk (PT), left pulmonary artery (LPA), right pulmonary artery (RPA), left pulmonary veins (LPV), right pulmonary veins (RPV), mitral valve (MV), tricuspid valve (TV), aortic valve (AV), and pulmonary valve (PV).
Using colored pencils (blue to represent deoxygenated blood, and red to represent oxygenated blood), draw colored arrows to show the direction of blood flow through all of the labeled structures. Make sure that you have arrows showing blood flow drawn in all blood vessels shown.
| From Venae Cavae | From lungs |
| –> | –> |
| –> valve | –> |
| –> | –> valve |
| –> valve | –> |
| –> | –> valve |
| –> | –> To Aorta |
| –> To lungs |

Correctly trace the path of blood flow through the heart from the vena cavae to the aorta. Use each of the terms only once: Aortic semilunar, Bicuspid (AV), Left Atrium, Left Ventricle, Pulmonary arteries, Pulmonary semilunar, Pulmonary trunk, Pulmonary veins, Right Atrium, Right Ventricle, Tricuspid (AV)
| From Venae Cavae | From lungs |
| –> 1. | –> 7. |
| –> 2. valve | –> 8. |
| –> 3. | –> 9. valve |
| –> 4. valve | –> 10. |
| –> 5. | –> 11. valve |
| –> 6. | –> To Aorta |
| –> To lungs |
ACTIVITY IV: Measures of Cardiovascular Health
Examine the heart model in lab showing coronary bypass surgery, and fill in the blank below:
The coronary bypass model in lab has ____ (number of) bypasses.
Your resting heart rate: ____ bpm OPTIONAL: Your heart rate after exercise: ____ bpm
Your estimated maximum heart rate (220 – your age): ____ bpm
Your target heart range during exercise (50-85% max): between ____ and ____ bpm
Why does heart rate increase during aerobic exercise?
Your blood pressure: ____/____How would your blood pressure be classified using the AHA’s guidelines?
