away from Chamber #2 of the heart?                                          _______________________

6. Is this blood oxygenated or deoxygenated?                                _______________________
7. How is this blood vessel different from other vessels in the

same class of blood vessels?                                                      _______________________

8. When the blood returns to the heart from its quick trip listed

                                                                                                                                                                               (Chamber #3)

9. Is the blood oxygenated or deoxygenated?                                 _______________________
10. What is the name of the blood vessel that brings this blood

into Chamber #3 of the heart?                                                     _______________________

11. How is this blood vessel different from other vessels in the

same class of blood vessels?                                                      _______________________

12. What is the name of the final (fourth) chamber of the heart

that blood enters?                                                                         _______________________

                                                                                                                                                                               (Chamber #4)

13. Upon leaving the fourth chamber of the heart, blood is

pumped away from the heart toward the rest of the body.

What is the name of the blood vessel that carries blood away

from the heart toward the body.                                                   _______________________

14. Is this blood oxygenated or deoxygenated?                                _______________________

Answer 1

1)Right atrium. Blood enters initially to Right atrium(1st chamber)

2)The deoxygenated blood comes from all parts of the body. After the right atrium, the blood moves to the right ventricle (2nd chamber)

3)Then the blood moves to the lungs

4)The pulmonary artery carries oxygen-poor blood to lungs

5)the blood is deoxygenated blood

6)All other arteries carry oxygenated blood but pulmonary artery carries deoxygenated blood

7)The oxygen-rich blood enters the left atrium(chamber 3)

8)Pulmonary veins bring the oxygenated blood from lungs to left atrium

9)all other veins carry deoxygenated blood to heart but pulmonary vein carries oxygenated blood

10)The final chamber is called the left ventricle. (chamber4)

11)Aorta carries blood away from heart to other parts of the body

12)the blood from heart to other parts of the body is oxygenated
