creation of red blood cells
erythropoiesis
makes cells
red marrow
fat storage
yellow marrow
blood cells last around
120 days
baby red blood cell
rubriblast
Erythropoietic Factor
Kidney
proteins from liver
erythroproteins
oxygen carried by heme proteins bound directly to...
ferrous iron
s- shaped
sigmoid
hemoglobin, chlorocruorin, hemerythrin, and hemocyanin (RP)
Respiratory Pigments
4 globin polyprotein subunits each containing heme molecule
Hemoglobin
takes out old/decrepit blood cells
spleen
new RBC entering circulation still containing polyribosomes & ribosomes w/ reticulated net - like appearing strands.
reticulocyte
circulating fluid kept within a closed circulatory
system in vertebrates
blood
circulating fluid in animals with an open
circulatory system, e.g. insects.
hemolymph
respiratory function
Red blood Cells
phagocytosis of dead cells & foreign material, cellmediated immunity
WBC function
coagulation
function of platelets
The percentage of the blood that consists of red cells
hematocrit or packed cell volume.
= the volume of ECF in the circulatory system
Plasma volume
erythrocyte (RBC) count, hemoglobin (Hgb) concentration and packed cell volume
hematologic parameters
has important osmotic effects since their high mol wt confines them inside the capillaries and coelomic space
Proteins
(COP) is the osmotic pressure
due to proteins.
colloid osmotic pressure
effect of protein on the distribution of other charged solutes
the Donnan effect
animal - normal, plant -flaccid cells
isotonic
Lysing - animals and turgid in plants
Hypotonic solution
called shriveled cells in plants and animals
hypertonic solution
capillary forces tending to keep water within the vascular space
plasma oncotic forces and tissue hydrostatic pressure
forces tending to drive water out of the vascular space
plasma hydrostatic pressure and tissue oncotic pressure
Under _____ conditions post capillary forces tending to keep water within the vascular space are ___against forces tending to drive water out of the vascular space
Normal; balanced
Pcap tends to move fluid outward through the capillary membrane
capillary pressure
Four primary factors determine fluid movement through the capillary membrane:
Starlings forces - Kf [ (Pcap - Pif) - (IIp - IIif)]
balance of ____ & _______ across a capillary causes filtration at the arterial end and reabsorption at the venous end of the capillary;
hydrostatic & colloid osmotic forces -overall filtration of fluid
measures the mean or
average size of individual red blood cells. To obtain the MCV,
the hematocrit is divided by the total RBC count. The MCV is
an indicator of the size of red blood cells. If the MCV is low,
the cells are microcytic or smaller than normal.
Mean corpuscular volume (MCV
measures the
amount, or the mass, of hemoglobin present in one RBC. The
weight of hemoglobin in an average cell is obtained by dividing
the hemoglobin by the total RBC count. The result is
reported by a very small weight called a picogram (pg).
Mean corpuscular hemoglobin (MCH
measures proportion of each cell taken up by hemoglobin -results reported in percentages, reflecting proportion of hemoglobin in RBC -hemoglobin is
divided by hematocrit & multiplied by 100 to obtain
Mean corpuscular hemoglobin concentration (MCHC)
fewer, larger RBCs
Lower hematocrit
Lower Hgb content
Lower RBC counts
Larger mean cell volume - larger mean cell Hgb concentration
Similar mean cell Hgb concentration (MCH)
Lower Vertebrates
-hemoglobin of muscle - structure contains one protein chain, a heme group (with a water molecule bound
to the iron)
myoglobin
Acidification or increased pCO2 lowers the oxygen-carrying capacity of hemoglobin
The root effect
Bone marrow stem cell -Decreased #WBCs -increased
myeloblast -leukopenia -leukocytosis
