The viscosity of blood is due more to______
erthrocytes
sodium

albumin
Erythrocytes transport oxygen and
transport some carbon dioxide
nutrients
defend the body against pathogens
initiate blood clottin
Most oxygen is transported bound to
Heme groups in hemoglobin
the plasma membrance of erythorcytes
alpha chains in hemoglobin
beta chains in hemoglobin
If all the molecules of hemoglobin contained in RBCs were free in the plasma
It would significantly increase blood osmolarity
it would considerably increase blood oxygen carrying capacity
it would facilitate delivery of oxygen into tissues supplied by small capillaries
it would drastically increase osmotic colloid pressure
An increased erythropoietin EPO output by the kidneys leads to all of the following except
Increased hypoxemia
increased blood osmolarity
increased blood viscosity
increased hematocrit
Many RBC die in the
spleen and liver
red bone marrow
stomach and liver
lymph nodes and thymus
All these can lead to polycythemia except

is more likely to cause anemia than any of the other factors below
Renal disease
smoking
high altitude
any factor that creates a state of hypoxemia
Anemia has these potential consequences

D; A and B
The main reason why an individual AB Rh negative canoot donate blood to an individual a RH positive is because.
Anti-B antibodies in the recipient will agglutinate RBS of the donor
Anti-B antibodies in the donor will agglutinate RBCs of the donor
Anti-A antibodies in the donor will agglutinate RBCs of the recipient
Anti-D antibodies in the donor will agglutinate RBC of the recipient
