Heart, Blood Vessels, and Blood

Normal Function

The heart, blood vessels and blood make up a complex delivery system. The heart acts as a muscular pump, forcing blood to circulate through a closed system of tubes that are blood vessels. Blood containing nutrients are pumped from the heart to the tissues in blood vessels called arteries. Blood that contains wastes is pulled from tissues into blood vessels called veins and circulated to organs to be eliminated from the body.

Seek assistance with dizziness, irritability, low urine volume and fluid retention with puffy or hard tissues, pallor of tissue of lips, inside the mouth, and inside the eyelid particularly if accompanied by lack of energy and a faster rate of breathing.

Arteries that circulate nutrients become hard, inelastic and thick walled.

Pressure exerted by the blood in the vessel increases.

Blood vessels respond slowly to changes in pressure.

Microscopic blood vessels become fragile and may burst resulting in bruising and bleeding under the skin.

Reduce daily stress.

Eliminate smoking.

educe fat intake, and excessive body weight. Encourage regular activity within toleration.
