PHLEB 1 Flashcards
3 major organs in the Circulatory System
- Heart
- Blood Vessels
- Blood
- Delivers oxygen & nutrients
- Removes waste products
- Helps in the coagulation process
- Regulates body temperature
- Important in body defense (WBC’s in the blood)
Circulatory System
Parasite
Eosinophil
Bacteria
Neutrophil
Viruses
Lymphocyte
Allergy
Basophil
Phagocytosis, 1st respondent in blood clot
Monocyte
Blood Vessels
Arteries, Veins, Capillaries
oxygenated blood vessel
Arteries
deoxygenated
Veins
exchange of gas
Capillaries
- Large thick-walled vessel
- Propel oxygen-rich blood (bright-red)
- Away from the heart to the capillaries
artery
small thin vessels that connect arteries to capillaries.
Arterioles
- Largest artery
- Distributes oxygenated blood through the body
Aorta
- Located at the thumb site ; pulse rate
Radial Artery
- Groin area ; arterial puncture of RT
Femoral Artery
- Side of the neck ; emergency pulse rate
Carotid Area
- Located at the lungs
- Only artery that does not carry oxygenated blood
Pulmonary Artery
- Thinner walls than artery
- Nutrients & wastes from the capillaries back to the hearts
- Carries deoxygenated blood (oxygen pull blood)
- Deoxygenated blood – DARK RED
Veins
Color of Arterial Blood
Bright-Red
Color of Veinous Blood
Dark Red
Dark-Red
Deoxygenated Blood
Bright-Red
Oxygenated Blood
- Small veins that connect capillaries to large veins
- more numerous than artery
- generally superficial ; more prominent
Venules
Veins of Outer Cubital Fossa
Median Cubital Vein, Cephalic Vein, Basilic Vein
Median Cubital Vein
1st choice
Cephalic Vein
2nd Choice
Basilic Vein
3rd choice
- Carries deoxygenated blood from the upper part of the body to the heart
Superior Vena Cava
- Carries deoxygenated blood from the lower part of the body to the heart
Inferior Vena Cava
- Longest vein in the body
- Principal vein of the leg
Great Saphenous Vein
