3. Cardiovascular / (Circulatory) System

4. Cardiovascular System
Cardio = “heart” Vascular = “vessels”

5. Cardiovascular System
Cardio = “heart” Vascular = “vessels”
Made up of heart, vessels, and blood

6. Cardiovascular System
Cardio = “heart” Vascular = “vessels”
Made up of heart, vessels, and blood
Closed system—blood stays inside the vessels

7. Cardiovascular System
Cardio = “heart” Vascular = “vessels”
Made up of heart, vessels, and blood
Closed system—blood stays inside the vessels
Blood only flows one-way
