function of fibrinogen
clotting
function of immunoglobulins
defense
function of albunin

Name the leakocytes
basophils, lymphocytes, neutrophils, monocytes, and eosinophils
how much of the blood is plasma?
55% (the other 45% is cellular elements)
how long to RBC’s live?
120 days
what is the name for RBC production and what controls it?
Erythropoiesis, and it is controlled by erythropoietin
where do RBC’s get their source of energy?
Glycoloysis
hemoglobin is a repiratory pigment. Is it better for an organism to have it’s respiratory pigment enclosed in a cell or free floating? why?
enclosed. Because it can be compacted and more can be carried at a time.
what is the denaturing of Hemoglobin as a result of low pH called?
The Bohr Effect
Cooperativity property of hemoglobin:
The first binding of an O2 molecule is hard but once that happens, it is easy to add more
Allosteric property of hemoglobin
changes to one shape to get O2 and another shaper to release it
High blood acidity is a positive or negative allosteric modulator to hemoglobin?
Negative
where is interstitial fluid
between the body cells and the capillary wall
only 25% of the CO2 in the body is carried by hemoglobin. Where is the rest?
5% is free gas, but the other 70% reacts with the water in the RBC to form Carbonic Acid (H2CO3) which is broken up into H+ and HCO3- (bicarbonate) and then put back together when it reaches the lungs and released as CO2 and water. Back where it began
what are the 3 places where blood goes through 2 capillary beds?
hepactic portal system, the anterior pituitary, and the ?
