1. The Circulatory System

2. What is the purpose of the circulatory system?

3. What is the purpose of the circulatory system?
To move materials through out the body:
Oxygen
Carbon dioxide & other wastes
Nutrients
Hormones
Antibodies

4. What are the 3 types of circulation?

5. What are the 3 types of circulation?
System – between heart to body systems
Pulmonary – between heart & lungs
Coronary – between heart & heartS

6. What is coronary circulation?

7. What is coronary circulation?
The flow of blood to and from the tissues of the heart
When the coronary circulation is blocked, oxygen and nutrients cannot reach all the cells of the heart. This can cause a heart attack

8. What is coronary circulation?
The heart receives the oxygen and nutrients that it needs from the blood
The blood also carries away wastes from the heart's cells

10. What is pulmonary circulation?

11. What is pulmonary circulation?
The flow of blood through the heart to the lungs and back to the heart

12. Trace the pathway of blood from heart to lungs and back.

13. Trace the pathway of blood from heart to lungs and back.
Blood, high in carbon dioxide and low in oxygen, returns from the body to the heart. It enters the right atrium through the superior and inferior vena cavae.

14. Trace the pathway of blood from heart to lungs and back.
B. The right atrium contracts, forcing the blood into the right ventricle. When the right ventricle contracts, the blood leaves the heart and goes through the pulmonary artery to the lungs. The pulmonary arteries are the only arteries that carry blood that is high in carbon dioxide

15. Trace the pathway of blood from heart to lungs and back.
C. Oxygen-rich blood travels from the lungs through the pulmonary vein and into the left atrium. The pulmonary veins are the only veins that carry oxygen-rich blood.

16. Trace the pathway of blood from heart to lungs and back.
D. The left atrium contracts and forces the blood into the left ventricle. The left ventricle contracts, forcing the blood out of the heart and into the aorta.

17. What are the functions of the systemic circulation system in your body?

18. What are the functions of the systemic circulation system in your body?
It moves oxygenated (oxygen-rich) blood to organs and body tissues.
It returns un-oxygenated (oxygen-poor) blood to the heart.

19. List the parts of the circulatory (or cardiovascular) system:

20. List the parts of the circulatory (or cardiovascular) system:

26. Describe veins

27. Describe veins Blood vessels that carry blood back to the heart
Have one-way valves that keep blood moving toward the heart

28. What is blood pressure?

29. The force of the blood on the walls of the blood vessels.

The force of the blood on the walls of the blood vessels.

30. What is the purpose of blood vessels?

31. What is the purpose of blood vessels?
Blood vessels carry the blood to every part of your body

32. What does blood do?

33. What does blood do? Blood moves oxygen and nutrients to cells
Carries carbon dioxide and other wastes away from the cells
Sometimes the blood carries substances made in one part of the body to another part of the body where they are needed

34. What is the heart?

35. What is the heart?
An organ made of cardiac muscle tissue

36. Describe the heart

37. Describe the heart
Located behind your breastbone, called the sternum, and between your lungs
Has four compartments called chambers
The two upper chambers are called the right and left atria
The two lower chambers are called the right and left ventricles

38. Describe the heart
During one heartbeat, both atriums contract at the same time
Then, both ventricles contract at the same time
A one-way valve separates each atrium from the ventricle below it

39. Describe the heart
The blood flows only in one direction from an atrium to a ventricle, then from a ventricle into a blood vessel
A wall prevents blood from flowing between the two atriums or the two ventricles
This wall keeps blood rich in oxygen separate from blood low in oxygen
If oxygen-rich blood and oxygen-poor blood were to mix, your body's cells would not get all the oxygen they need
