CIRCULATION OF BLOODCIRCULATION OF BLOOD
Pulmonary Pulmonary ccircuirculationlation
heart - lungheart - lung
Systemic CircSystemic Circulationulation

PULMONARY PULMONARY CIRCULATIONCIRCULATION
oxygen-poor oxygen-poor bloodblood
enters heart from enters heart from the body and goes the body and goes to lungsto lungs

oxygen and loses oxygen and loses carbon dioxidecarbon dioxide

SYSTEMIC CIRCULATIONSYSTEMIC CIRCULATION
the aorta divides the aorta divides into numerous into numerous branches called branches called arteriesarteries

MEASUREMENTMEASUREMENT OF BLOODOF BLOOD CIRCULATIONCIRCULATION
eeven when the ven when the blood pressure is blood pressure is normal, blood normal, blood circulation may be circulation may be seriously impaired!seriously impaired!
aawareness of the wareness of the causes and effects causes and effects of poor blood of poor blood circulation is very circulation is very importantimportant
