Describe the functioning and relative amounts of the components of blood including:RBC"s (erythrocytes), structure and hemoglobin.
transport Oxygen and carbon dioxide
No organelles and nucleus
Produced in bone marrow, 3 mil RBC's/sec
Recycled in liver, spleen
120 day lifespan
do not reproduce
circulate body in 30-60 sec.
Bring oxygenated blood to toe cell, and deoxygenated blood back up to exhale
very imp in RBC
enzyme critical in CO2 transport
CO2 accumulation in the blood results in acid formation (Carbonic acid)
Carbonic Acid brings down blood Ph below 7.4.
maintains proper blood ph by converting CO2 to HC)3 (bicarbonate ion)
red pigment, gives blood its color
binds and transports O2 and CO2
4 polypeptide subunits (2 alpha, 2 beta)
4 heme group (holds 1 O2)
Oxyhemoglobin (bright red)
Deoxyhemoglobin (dark red)
IRON binds oxygen
