1. What is the cardiovascular system and what organs are in that system?
WARM-UP Pt. I & II: Answer with 1 paragraph for each with a minimum of 4 sentences.
Describe the differences between afferent and efferent neurons and provide the alternate names for them?
What is the cardiovascular system and what organs are in that system?

2. Circulatory System & Cardiovascular System
You sleep...but does you body? Your body is working all the time. The circulatory/cardiovascular system is the system that keeps it going!

5. These systems include the heart, different types of blood vessels, and the blood.
Circulatory/Cardiovascular System organs and tissues that transport essential materials to body cells and remove their waste. This system and the circulatory are often referred to interchangeably.

6. 3 types of blood vessels: Arteries, Capillaries, and Veins
The bodies highway!
The HEART is the muscle that acts as the pump of the circulatory system. It pushes blood through tubes called blood vessels.
3 types of blood vessels: Arteries, Capillaries, and Veins

7. Veins: carry blood from all parts of the body back to the heart.
Blood Vessels
Arteries: carry blood away from the heart to various parts of the body.
Veins: carry blood from all parts of the body back to the heart.
Capillaries: carry blood to and from almost all body cells and connect arteries and veins.

8. KNOW: Aorta, right/left atrium, right/left ventricle and blood flow through heart.

9. KNOW: Vena Cava, heart, right lung, left lung, aortic artery, carotid artery, femoral artery, femoral vein.

10. The heart!
4 chambers: the top chambers are called ATRIA or “rooms”, blood enters the heart through the atria.
The bottom chambers are called VENTRICLES and the blood leaves the heart through them.

11. Blood Pressure
This is the force of blood pushing against the walls of the blood vessels.
It is highest during the heart contraction (systolic) and lowest when the heart relaxes (diastolic).

12. Blood! It’s more than RBC
Red Blood Cells(RBC) carry oxygen to the cells in the body and carry away some waste.
White Blood Cells(WBC): helps various body systems destroy disease causing bacteria.

13. Hemoglobin: red protein responsible for binding to oxygen in the blood
More about blood stuff!
Platelets: are small disk shaped structures that help you blood to clot.
Hemoglobin: red protein responsible for binding to oxygen in the blood

14. Blood is more than a red color.
Blood Types: A, B, AB, O. Your blood type is inherited and remains the same your whole life. You should know your type.

15. Compatibility matters!
O is the universal donor and AB the universal recipient.

16. Rh factors. Rh- can only receive from negative but RH+ can receive from RH+ and Rh-. The blood type and Rh factor must be compatible for a transfusion to occur.

17. Problems of the Circulatory System
Hypertension: high blood pressure. Can lead to kidney failure, heart attack, and stroke.
Heart attack: or blockage of blood flow to the heart.
Stroke: results from blood clot in the brain or torn blood vessel.

18. Arteriosclerosis: hardening of the arteries
More problems
Arteriosclerosis: hardening of the arteries
Anemia: is abnormal low level of hemoglobin, the protein that binds to oxygen in the RBC.
Leukemia: cancer that causes WBC to interfere the production of other blood cells

19. More problems
Sickle cell anemia: inherited condition in which there are not enough RBC to transport adequate oxygen
Hemophilia: rare disorder in which blood does not clot normally due to lack of clotting protein.

20. The organs that supply your blood with oxygen.
RESPIRATORY SYSTEM
The organs that supply your blood with oxygen.
Breathing moves oxygen into and carbon dioxide out of your body.
