The part of hemoglobin that binds iron is
O alpha globulin 2
Obeta globulin 2
alpha globulin 1
O beta globulin 1
heme
biliverdin
macrophages
urobilinogen
bilirubin
Erythrocytes are continually replaced. Worn-out erythrocytes are lysed in the spleen as they pass through splenic
cords in the spleen.
digest these cell parts, and separate heme from the globin units
of hemoglobin. The globin proteins are broken down into amino acids and recycled. The heme pigment is
converted into
, then
, and released into the blood. It is
concentrated in urine, producing its yellow color. The liver removes additional bilirubin and secretes it into bile.
When released into the small intestine, bacteria transform it into
which makes feces
brown.

- From the given statement which is true?arrow_forwardHemoglobin will bind oxygen and release CO2 in places where there is a higher concentration of O2, lower concentration of CO2, lower temperature and lower acidity (as it is in lungs) and will do the reverse – release oxygen and bind CO2 - in places where there is a lower concentration of O2, higher concentration of CO2, higher temperature and higher acidity (as it is in working muscles). True False While white blood cells never leave the circulation, red blood cells regularly leave it and travel by lymphatic system or find home in other tissues, e.g., lymph nodes, spleen, etc. True False Blood clotting (coagulation) is a complex process involving many factors and it exhibits positive feedback loops: many of the factors also stimulate production of their own precursors.
