binds reversibly with oxygen and makes up 97% of cell volume

Hemogoblin

Most blood cells originate in-

bone marrow and do not divide

tiny connecting blood vessels

Capillaries

provides flexibility to change shape

Spectrin

dedicated to respiratory gas transport

RBCs

is composed of 4 polypeptide chains

goblin

what are the 4 polypeptide chains?

2 alpha & 2 beta chains

What produces Oxyhemoglobin?

O2 loading in lungs

What produces Deoxyhemoglobin?

O2 unloading in lungs

is the process of RBCs that takes about 15 days

erythropoiesis

red blood cells live up to-

120 days/4 months

Percent of blood volume that is RBCs

Hematocrit

Show scarlet red blood

High O2

Show dark red blood

Low O2

Makes up 60% of plasma proteins

Albumin

remain in blood not taken up by cells; produced mostly by liver

Plasma protein

Platelet formation is regulated by

thrombopoietin

Formed in myeloid line from

megakaryoblast

• Mitosis occurs but no cytokinesis, resulting in large stage IV cell with multilobed nucleus ​

megakaryoblast

arise from myeloid line stem cells​

Myeloblasts

accumulate lysosomes​

Promyelocytes

accumulate granules​

Myelocytes

nuclei form curved arc​

Band cells

production of WBCs are stimulated by two types of chemical messengers from red bone marrow and mature WBCs​

Leukopoiesis

act against virus-infected cells and tumor cells​

T lymphocytes (T cells)

give rise to plasma cells, which produce antibodies​

B lymphocytes (B cells)

lack visible cytoplasmic granules​

Agranulocytes

Neutrophils, eosinophils, basophils​ are

Granulocytes: three types​
