Circulatory system consists of the:
Heart
Blood vessels
Blood
3 Types of Blood Vessels:
Arteries
Veins
Capilllaries
Structure of blood vessels (superficial to deep):
Tunica
adventitia
- connective tissue
Tunica
media
- smooth muscle & elastic tissue
Tunica
intima
- endothelial cells
Lumen
- space within a blood vessel through which the blood flow
Arteries
- large, thick-walled blood vessels that propels
oxygenated
blood to the
capillaries
Veins
- thin-walled blood vessels that carry
deoxygenated
blood back to the heart
Venipuncture
- the procedure for removing blood from a vein for analysis
Veins of choice during venipuncture:
First choice -
Median cubital veins
Second choice -
Cephalic vein
Last choice -
Basilic vein
Capillaries
- smallest blood vessels that connect arteries and
veins
; site of gas exchange in the blood
Electrocardiogram
(
ECG
) - measures the cardiac cycle by placing electrodes connected to a recorder on the patient's arms, legs, and chest
The heart contracts approximately
60
to
80
times per minute, which represents the pulse rate
Arrythmia
- irregular pulse rate
Bradycardia
- pulse rate less than 60 bpm
Tachycardia
- pulse rate greater than 100 bpm
Average BP for an adult is
120/80
mmHg.
An average adult has a blood volume of
5
to
