Blood
|
Liquid connective tissue that consists of cells surrounded by a liquid extracellular matrix
|
|
|
Interstitial fluid
|
fluid that bathes body cells
|
|
|
Transportation
|
Transports oxygen from lungs to the body cells, and carbon dioxide from body cells to the lungs. Carries nutrients from gastrointestinal tract to body cells and hormones from endocrine glands to other body cells |
|
|
Regulation
|
Circulating blood helps maintain homeostasis of all body fluids. Regulates pH through buffers chems converts strong acids or bases into weak ones Adjust body temp by heat absorb or intake of water |
|
|
Protection
|
blood clots protection against infections or diseases |
|
|
blood plasma
|
is 91.5% water 7% protein} Albumins Globulins Fibrinogen 1.5%other solutes} Electrolytes nutrients,regulatory substances, gases, waist products. |
|
|
Formed Elements |
Platelets150,000-400,000 White blood cells 5000-10,000 Red blood cells 4.8-5.4 million |
|
|
White Blood cells
|
Neutrophils -------60-70% Lymphocytes -----20-25% Monocytes --------3-8% Eosinophils --------2-4% Basophils ---------.5-1.0% |
|
|
Hematocrit
|
The % of total blood volume occupied by RBC
|
|
|
Polycythemia
|
when the % of RBC is abnormally high |
|
|
Hemopoiesis
|
the process by which the formed elements of blood develop |
|
|
Pluripotent stem cells |
derived from mesenchyme, theses cells can develop in to any diff types of cells
|
|
|
Myeloid stem cells
|
Are produce from pluripotent cells in red bone marrow. they begin in red bone marrow and give rise to red blood cells, monocytes, neutrophils ,platelets, eosinophil, basophil, and mast cells
|
|
|
Lymphoid stem cells
|
produced from pluripotent cells in red bone marrow. Begin the development in red bone marrow but finish in lymphatic tissue, and also produced natural killers, B lymphocytes, t Lymphocytes. |
|
|
Progenitor cells
|
produce during hemopoiesis some myeloid stem cells become this cells can't reproduce them selves, they are committed to give rise to more specific elements of the blood |
|
|
CFs
|
Colony forming units ab to indicate mature elements in the blood that they will produce. |
|
|
CFU-E |
Produces Erythrocytes (RBC) |
|
|
CFU-Meg |
Produces Megakaryocytes the source of platelets |
|
|
CFU-GM
|
produces granulocytes & monocytes |
|
|
Precursor cells
|
same as blast its the second generation
|
|
|
Hemopoietic growth factor
|
regulate the differentiation and proliferation of particular progenitor cells |
|
|
Erythropoietin
|
increase the # of RBC precursors, produce by cells in kidneys that lie between the kidney tubules
|
|
|
Thrombopoietin
|
hormone produced by liver cells that produce platelets by megakaryocytes
|
