TOPIC 5 Flashcards
is responsible for
transporting materials throughout the
entire body
Circulatory System
circulated through the blood
vessels by the heart to deliver oxygen and
nutrients to the cells and transport waste
products to the organs that remove them
from the body
Blood
Components OF CS
HEART
BLOOD
BLOOD VESSELS
Carry blood away
from the heart
Arteries
Links atrioles to the veins
Capillaries
Carry blood towards the heart
Veins
Large vessels
Arteries
Carry blood from heart to tissues of body.
● Carry oxygen rich blood, with the exception of pulmonary arteries
Arteries
Thick walls-need to withstand pressure produced when heart pushes blood
into them.
Arteries
Smallest blood vessels
Capillaries
Walls are only one cell thick and very narrow
Capillaries
Important for bringing nutrients and oxygen to tissues and absorbing CO2
and other waste products.
Capillaries
Once blood has passed through the capillary systems it must be returned to
the heart. Done by veins
Veins
Walls contains connective tissue and smooth muscle
Veins
Largest veins contain one way valves that keep blood flowing toward heart.
Veins
It is the first choice for venipuncture
Median
It is well anchored, tends to be less painful to puncture, and is not as close to major nerves or arteries as the others, making it generally the safest one
to use.
Median
it is the second-choice vein for venipuncture
Cephalic
It is often harder to palpate than the median cubital vein but is fairly well anchored and often the
only vein that can be palpated in obese patients.
Cephalic
it is the last-choice vein for venipuncture in either venous distribution pattern.
Basilic
force of blood on the wall of the arteries is known as
Blood pressure
the first number taken, is the force felt in
the arteries when the ventricles contract.
Systolic
the second number taken, is the force of
the blood on the arteries when the ventricles relax.
Dystolic
What percent of your body is blood
8%
