Human Anatomy
Two Types of Valves & their location
Atrioventricular Valve = at the entrance to the ventricles
Semilunar Valve = exit the ventricles
What is Anemia?
A condition in which the blood doesn't have enough healthy red blood cells or hemoglobin
Define Coronary Circulation
Blood is supplied to the heart by the blood vessels
What is Thixotropic Gel Separator? What activates it?
A polymer solution that positions between cells & serum or plasma; centrifuge is used to activate.
HgB, FBS, RA Factors, Blood Culture, PT
Blood Culture (yellow), PT (light blue), RA Factor (red), HgB (lavender), Glucose (gray)
Endocardium = Innermost layer
Myocardium = Middle layer
Epicardium = Exterior layer
Name the pressure during contraction of ventricles
Systolic Pressure
(Upper Number in Blood Pressure Reading)
Three Objectives of Phlebotomy
Diagnosis, Monitoring & Therapy
Which tube allows for short draw?
Red Tube (Serum).
(No anticoagulant added so no ratio is needed to adhere to)
aPTT, Glucose, Uric Acid, Electrolyte
aPTT (light blue), Uric Acid (red), Electrolyte (green), Glucose (gray)
Function of the 4 Types of Tissue:
Epithelial, Muscle, Nerve & Connective
Epithelial = covers & protects the body (skin & organ linings)
Muscle = contracts to produce movements (cardiac, skeletal & smooth)
Nerve = ability to transmit electrical impulses
Connective = supports & connects body (fat, cartilage, bone & blood)
Define Pulmonary Circulation
Movement of blood between the heart to lungs
(deoxygenated from heart to lungs & oxygenated from lungs to heart)
What is Citrate Phosphate Dextrose?
CPD is a special anticoagulant used by blood banks (transfusions) to stabilize blood specimen PH & dextrose to help keep cells alive
Reasons to do Capillary Puncture
1) Difficult Veins
2) Thrombotic Tendencies
3) Age (infants / geriatrics)
4) Only Small Specimen Needed
BMP, CBC, LFT, Blood Alcohol
BMP & LFT (green), CBC (lavender), Blood Alcohol (gray)
Name the Body Planes (3 total)
Frontal (coronal) plane: vertically, front and back portions.
Sagittal (medial) plane: vertically, right and left portions.
Transverse plane: horizontally, upper and lower portions
What is Sodium Polyanethol Sulfonate?
SPS is a special anticoagulant used to reduce production of complement (protein that destroys bacteria); used in Blood Culture tests
Name the pressure during relaxation of ventricles
Diastolic Pressure
(Lower Number in Blood Pressure Reading)
What is the correct order of draw?
Yellow, Light Blue, Red, Green, Lavender & Gray
BUN, GTT, HBs, RBC Differential, LFT
BUN & HBs (red), LFT (green), RBC Differential (lavender), GTT (gray)
What layer of skin is vascular?
Dermis
Veins that carries oxygenated blood
Pulmonary Veins
Define Systemic Circulation
The system of arteries supplying oxygenated blood to the body and the veins returning the deoxygenated blood from tissues of the body back to the heart
What information is found on a Requisition Form?
Patient's Name & DOB, Physician's Name, Test(s) Requested, Test Status (STAT, Fasting,etc)
BMP, CBC, GCT, PT
PT (Light Blue), BMP (green), CBC (lavender), GCT (gray)
