once they leave red bone marrow formed elements do not?
|
devide
the exception is? |
lymphocytes
|
|
|
what cells have the capacity to develope into many different types of cells?
|
Pluripotent stem cells.
these cells produce what 2 types of stem cells? |

in the red bone marrow
|
|
|
|
lymphoid cells start their development in the red bone marrow and finish it ?
|
in the lymphoid tissue
|
|
|
|
which stem cells are made is controlled by different homones called?
|

such as? |
erythopoietin- stimulates RBCs
thrombopoietin- platelets colony stimulating factors CSFs interleukins-WBCs |
|
|
RBCs are also called?
|
erythrocytes
|
|
|
|
RBCs have no nucleus, and other organells; they can not?
|
devide
they have no mitochondria so they use no? |
oxygen
|
|
|
the function of RBCs?
|
carry oxygen throughout the body
|
|
|
|
what is found in RBCs?
|
hemoglobin molecules; 280 million!
they contain? |
globin protien, which consists of 4 polypep chains.
|
|
|
hemoglobin can bind to how many oxygen molecules?
|
4
this is becasue of? |
heme in each of the globin's 4 chains, which contains iron ions that combine with oxygen
|
|
|
hemoglobin also transport 23% of?
|
waste carbon dioxide
which combines with? |
amino acids of globin
|
|
|
nitric oxide (NO) binds to?
|
hemoglobin
when hemoglobin releases NO is causes? |
vasodilation, wich improves blood flow and oxygen delivery

|
phagocytic macrophages in the?
|
spleen and liver
|
