PHLEBOTOMY NATIONAL EXAM
(NHA)
Characteristics imperative to a phlebotomist - Dependability, honesty, integrity, empathy and
compassion, professional appearance, interpersonal skills
Circulatory system function - deliver oxygen, nutrients, hormones, & enzymes to cells and transport
cellular waste (CO2) to organs where they can be expelled
The two circulations - Pulmonary & Systemic
Pulmonary circulation - carries deoxygenated blood from the right ventricle to the lungs and returns
oxygenated blood from lungs to left atrium
Where does oxygenation take place in the lungs? - alveoli
Systemic circulation - carries oxygenated blood from left ventricle throughout the body
Upper chambers of the heart - right and left atria
lower chambers of the heart - right and left ventricle
tricuspid valve - atrioventricular valve, situated between right atrium and right ventricle
**to remember this valve is on the right side of the heart-- people TRY to be RIGHT
pulmonic valve - semi-lunar valve situated between the right ventricle and the pulmonary artery
Mitral valve (or bicuspid) - atrioventricular valve located between the left atrium and left ventricle
, aortic valve - semi lunar valve situated between the left ventricle and aorta
Flow of blood through the heart - Superior and Inferior Vena Cavae< Right atrium< tricuspid valve< right
ventricle< pulmonic valve< pulmonary artery< lungs< pulmonary vein< left atrium< mitral (bicuspid)
valve< left ventricle< aorta< rest of body
Three layers of the heart - Endocardium, myocardium, epicardium
Blood vessels - arteries, arterioles, capillaries, venules, veins, superior & inferior vena cavae
aorta, arteries, and arterioles carry_____ blood _______ the heart - oxygenated & away from
venules, veins, and superior and inferior vena cave carry _____ blood ________ the heart -
deoxygenated & back to
The average adult has ______ liters of blood - 5-6
Plasma comprises how much of circulating blood? - 55%
Plasma contains.... - proteins, amino acids, gases, electrolytes, sugars, hormones, minerals, vitamins, and
water
What percent of plasma is water? - 92%
Formed elements comprise what percent of circulating blood? - 45%
another name for red blood cells... - Erythrocytes
What makes up the formed elements? - Red blood cells, White blood cells, and platelets
