What is the purpose of the circulatory system?
Bring O2 in and take CO2 out!

BLOOD VESSELS
AORTA (HIGHWAY)BRINGS O2 -BLOOD FROM HEART TO BODY
ARTERIES (BUSY STREETS)BRINGS O2-BLOOD TO BODY

BLOOD VESSELS CONTD.. CAPILLARIES ( DRIVEWAYS) DROPS O2 TO CELLS PICKS UP CO2
VEINS (SLOW STREETS) BRINGS CO2BLOOD TO HEART

DID YOU UNDERSTAND? WHAT IS THE BIGGEST SUPERHIGHWAY? AORTA WHAT ARE THE SMALLEST BLOOD VESSELS? CAPILLARIES WHICH VESSELS DROP OXYGEN OFF TO A CELL? CAPILLARIES WHAT DO VEINS CARRY? CARBON DIOXIDE-BLOOD WHICH VESSEL CARRIES BLOOD FROM HEART
TO LUNG? PULMONARY ARTERY
