Blood
Functions
Carry O2 to and from cells
deoxyhemoglobin; oxygen poor
oxyhemoglobin; oxygen rich
Distribute heat
blood drawn to core to retain heat
blood surfaced to peripheral tissues to release heat from body
Defense mechanism
use of lymphocytes
Homeostasis
carry hormones within bloodstream
Hemostasis
creates fibrin sheet in cascade of events with use of fibrinogen
Hemopoiesis
Production of blood cells and platelets
Influenced by hemopoietic growth factors
Erythropoietin
Thrombopoietin
Cytokines
Colony-stimulating factors
Interleukins
Lymphoid stem cells
Produce leukocytes/lyphocytes
Myeloid stem cells
Produce erythrocytes
Produce megakaryocytes
Result in platelets
Myeloblast lineage
Monocytes
3 granular leukocytes
Neutrophils
Eosinophils
Basophils
Formed Elements
Red Blood Cells
Erythrocytes
Transport gases mostly O2, some CO2
Made in red bone marrow
White Blood cells
Leukocytes
Made in red bone marrow and lymphatic tissue
Used for immunity
Platelets
Made of cell fragments
Used for hemostasis
Made in red bone marrow
Plasma
Extracellular matrix
Plasma Proteins
Albumin
Made in liver
Transport lipid molecules
Globulins
Alpha-globulins
Made in liver
Transport and maintain osmotic pressure
Beta-globulins
Made in liver
Transport and maintain osmotic pressure
Gamma-globulins
(Immuno-globulins)
Made in liver
Primarily for immune responses
Fibrinogen
Made in liver
Primarily used for blood clotting during hemostasis
Mostly water
Transport medium
