Question Answer
major components of whole blood fig 16.1)Plasma * Buffy Coat(formed element) * Erthrocytes (formed element)
relative amounts of each component fig 16.1)55%=Plasma*<1%Leulocytes/platelets*45%erythrocytes(hematocrit)
describe the role of the various plasma proteins table 16.1) contribute to osmotic pressure/water balance in blood/tissues
describe the function of each of the formed elements (p. 555erthrocyte=gas transport*hemoglobin=protein makes rbc*
describe the steps involved in blood clotting and the make-up of a clotVascular Spasm*Platelet Plug Formation*Coagulation (P.567)
identify theantigens & antibodies present that determine blood types &blood compatibilities (look at table 16.4)
describe the functions of the different white blood cells table 16.2), you do NOT have to identify the image of each one
explain the the conduction system of the heart (look at figure 17.15 (figure 17.14))Pacemaker Potential*Depolarization*Repolarization
explain how the heart is reflected in the EKG pattern (electrocardiogram)
what each deflection wave represents (look at figure 17.17 (figure 17.16))
explain what is occurring in the heart during each
describe how cardiac muscle differs from skeletal muscle and smooth muscle
state the components of plasma (look at table 16.1)
hematocritethrocytes 45% of total vol of blood
Distribution Function (O2)O2 from Lungs & Nutrients from Digestive Tract
Distribution Function (Waste)Metaboic Waste from Cells to Elimation Sites (Lungs/Kidneys)
Distribution Function (Hormones)Hormones from Endocrine ORgans to their Target Organs
Regulation Function Body Temp * PH Normalization * Maintain adequate fluid Volume
Protection Function Preventing Blood Loss & Preventing Infection
albuminmade by liver; Mainly contributes to Osmotic Pressure
Globulins (alpha/beta)made @liver; transport proteins that bind 2 lipids/metal ions/fat-soluble vitami
Globulins (gamma)Antibodies released by plasma cells during immune response
FibronogenMade @liver; makes fibrin threasds of blood clot
Clot retraction and repairallows the scab to form, and once the tissue and vessels have healed, the scab falls away
steps of the cardiac cycle in sequence isovolumic contraction, ejection, isovolumic relaxation, passive ventricular filling, active ventricular filling.
