PULMONARY VS SYSTEMIC CIRCULATION

PULMONARY-- Circulates blood from the heart to the lungs and from the lungs to the heart

**Right side of heart: RA-->RV-->PULMONARY TRUNK-->PULMONARY ARTERIES-->PULMONARY ARTERIOLES-->LUNGS (GAS EXCHANGE, BLOOD BECOMES O2ATED, CAPILLARIES)-->PULMONARY VENULES-->PULMONARY VEINS--> HEART (LA)

• ARTERIES (PULMONARY)- DeO2ated blood (away from heart)
• VEINS (PULMONARY)- O2ated blood (towards heart)

SYSTEMIC-- Circulates blood from the heart to the body (tissues and organs)

**Left side of heart: LA-->LV-->AORTA-->BRANCHES OF AORTA (ONE OF THE MANY PATHS)-->ORGANS AND BODY REGIONS 

• VEINS- DeO2ated blood (towards heart)
• ARTERIES- O2ated blood (away from heart)
