PERIPHERAL CIRCULATION
DEFINITION:
PERIPHERAL- Relating to or situated in the periphery of an organ or part of the body in relation to a specific reference point. Away from the center of the body.
PERIPHERY – the part of the body away from the center.
CIRCULATION –movement in the regular course, as the movement of the blood through the heart and vessels.
PERIPHERAL CIRCULATION-transport, passage, or movement of blood away from the center (heart), the route is the upper and lower extremities then back to the center (heart) again.
I. CIRCULATORY SYSTEM
the main transportation and cooling system of the body.
responsible for transporting materials throughout the entire body. It transports nutrients, water, and oxygen to your billions of body cells and carries away wastes such as carbon dioxide that body cells produce.
fluid distribution network
PARTS OF THE CIRCULATORY SYSTEM:
The Heart, The Blood, and The Blood vessels.
HEART
Heart weighs between 7 and 15 ounces (200 to 425 grams) and is a little larger than the size of your fist. An average adult contains 4.7 to 5.7 liters of blood
Responsible for pumping blood throughout the blood vessels by repeated rhythmic contractions
By the end of a long life, a person's heart may have beat (expanded and contracted) more than 3 billion times.
FOUR CHAMBERS OF THE HEART:
1. Right atrium - receives deoxygenated blood from the superior and inferior vena cava and pumps it into the right ventricle via the tricuspid valve
2. Right Ventricle - receives deoxygenated blood from the right atrium via the tricuspid valve and pumps it into the pulmonary artery via the pulmonary valve
3. LEFT ATRIUM- receives oxygenated blood from the pulmonary veins and pumps it into the left ventricle via the mitral valve.
4. LEFT VENTRICLE - receives oxygenated blood from the left atrium via the mitral valve, and pumps it into the aorta via the aortic valve. The largest and strongest chamber in the heart.
