Heart Lab Report

1. a) What is the difference in wall thickness between the aorta and vena cava?

b) Why is there this difference?

 

 

2. How do the right and left sides of the heart differ in:

Structure of the atrioventricular valves -

Thickness of the myocardium -

Oxygen content of the blood –

 

 

3. How do you account for the difference in muscle wall thickness between the two ventricles?

 

 

4. Write the term that matches each meaning. Be as specific as possible!

Vessels carrying blood away from heart -

Vessels carrying blood toward heart -

Chamber receiving blood returning from lungs -

Pumps blood to all parts of the body except lungs -

Wall between ventricles -

Prevents flow of blood back into ventricles -

Contraction phase of heart cycle -

Heart chambers that contract first -

Prevents flow of blood back into atria -

Relaxation phase of heart cycle –

 

 

5. What tissue composes the bulk of the heart?

6. List, in proper sequence, the passage of blood through the heart.  Name all the chambers, vessels, and valves that the blood contacts as it travels from the right atrium to the aorta.

 

 

7. a) All arteries of the adult body contain oxygenated blood except one. Which one and why?

b) All veins of the adult body contain deoxygenated blood except one. Which one and why?

 

 

8. Using simple terms, explain how the contraction of the atria and ventricles is controlled by the cardiac conduction system.

 

 

9. How do the arteries and veins differ in:

Direction of blood flow –

Thickness of wall -

Relative position in the skin-(superficial or deep) –

 

 

10. Standard pulse rate while at rest.

 

 

11. a) Pulse rate while lying down

Why does it change from the pulse rate given at 10?

b) Pulse rate while standing up

Why does it change from the pulse rate given at 11a?

 

 

12. Pulse rate after moderate exercise

Why does it change from the pulse rate given at 10?

 

 

13. Pulse rate after heavy exercise

Why does it change from the pulse rate given at 10?

 

 

14. Label blood flow from the concept map below:

1,2,3,4,5,6,7,8,9,10,11,12

 

 

15. Label the correct areas (1, 3, 4, 6, & 7) with the appropriate answer.
