CIRCULATORY SYSTEM
arteries
 arterioles
 veins
 venules
 capillaries
 heart

BLOOD

circulates through the body

carries nutrients (food) ,oxygen and many
other substances to all cells of the body

carries away waste products

without access to the blood, cells and body
tissues die
CIRCULATION OF BLOOD

Pulmonary circulation
heart - lung

Systemic Circulation
heart – tissue capillaries
PULMONARY CIRCULATION

oxygen-poor blood
enters heart from
the body and goes
to lungs

pulmonary artery
carries blood
deficient in oxygen
PULMONARY CIRCULATION

lung capillaries
blood absorbs oxygen
and loses carbon
dioxide

oxygen-rich blood

pulmonary veins
carry oxygen-rich
blood
SYSTEMIC CIRCULATION

oxygen-rich blood
returns to the heart
through pulmonary
veins

left ventricle pushes
the blood out through
the main artery, the
aorta
SYSTEMIC CIRCULATION

the aorta divides into
numerous branches
called arteries

arterioles – tissue
capillaries
SYSTEMIC CIRCULATION

tissue capillaries
near the body cells

blood delivers oxygen
and picks up carbon
dioxide
SYSTEMIC CIRCULATION

venules, veins
return the blood to the
right side of the heart

oxygen-poor blood
CAUSES OF IMPAIRED BLOOD
CIRCULATION

impaired or poor
blood circulation

result of age, lifestyle
or disease,
accumulation of free
radicals
CAUSES OF IMPAIRED BLOOD
CIRCULATION

lack of oxygen reduces the energy level in cells
and waste products accumulate in both muscles
and connective tissue

pain and other illness may occur in several places
in the body
SIGNS OF IMPAIRED BLOOD
CIRCULATION







pain while walking
muscle cramps (common at night)
cold hands and feet
restless legs
swollen legs and feet
slow healing of injuries/ wounds
myocardial infarction (heart attack)
stroke
MEASUREMENT OF BLOOD
CIRCULATION

even when the
blood pressure is
normal, blood
circulation may be
seriously impaired!

awareness of the
causes and effects
of poor blood
circulation is very
important
