Blood (definition)

-liquid connective tissue


-consists of cells surrounded by a liquid extracellular matrix


-heavier, thicker, and more viscous than water

Extracellular matrix (definition)

-known as blood plasma


-suspends various cells and cell fragments

Interstitial fluid (definition)

-fluid that bathes body cells


-constantly renewed by blood


-ECF plasma

Plasma(definition)

-w/o clotting proteins= serum


-plasma= whole blood-formed elements

Plasma-Albumins (function)

-important blood buffers


-maintains blood osmotic pressure


-produced by liver

Plasma-Globulins (function)

-alpha+beta: produced by liver, transport proteins


-gamma:immunoglobulins, antibodies

Clotting protein/Fibrinogen (definition+function)

-produced by plasma cells


-include fibrinogent prothrombin (from liver)

Formed elements (definition)

-composed of three principal components


-RBCs, WBCs, and platelets


-hemopoiesis:process to develop formed elements

RBCs (definition)

-proeythroblasts are precursor cells


-biconclave shape helps w/oxygen transport, large surface area

WBCs (definition)

-are leukocytes


-classified as either granular or agranular

Leukocytes (definition)

-precursor for all granular leukocytes is myeloblasts


-precursor for monocytes is monoblasts


-precursor for lymphocytes is lymphoblasts

Neutrophil (definition)

-are neutral to acidic and basic dyes


-take pale lilac color


-nuclei w/2-5 lobes;polymorphonuclear


-younger cells called 'bands'


-contain peroxidases+defensins

Neutrophil (function)

-phagocytes+destruction of bacteria and fungi


-defensins cause cytolysis


-first to arrive at sight of infection

Eosinophil (definition)

-granules stain red/orange with acidic dyes


-nucleus has 2 lobes (telephoic receiver)


-granules fill the cytoplasm

Eosinophil (function)

-have digestive enzymes


-lessen severity of allergy reaction (phagocytes antigen-antibody complex)


-combat parasites

Basophil (definition)

-nuclei bilobed/irregular

-granules not uniformed, veil nuclues


-stain blue/purple w/basic dyes

Basophil (function)

-liberate histamine (vasodilator)+herapin (anti-coagulant)


-involved w/inflammatory+hypersensitivity reactions

Lymphocytes (definition)

-rim of cytoplasm surrounds the nucleus


-small portion seen in blood


-rest are in lymphoid tissue


-large spherical


-stain dark purple in nucleus

Lymphocytes (function)

-t-lymphocytes work against viruses, bacteria, fungi, trnasplanted and mast tumor cells


-b-lymphocytes give rise to plasma cells that secrete antibodies


-immune response is through t+b cells

Monocytes (definition)

-dark purple nucleus


-nucleus is kidney/horse-shoe shaped


-pale blues foamy cytoplasm

Monocytes (function)

-combat viral, fungi, and intra-cellular bacterial infection


-last to arrive at sight of infection


-engulf microbes and debris


-migrate to tissue to form macrophages; fixed macrophages and migrate macrophages

Platelets (definitions)

-are fragments of cells enclosed in plasma membrane


cytoplasm+mitochondria are there


-no nucleus


-formed from megakaryocytes

Platelets (function)

-form platelet plug in homeostasis


-release chemicals that promote vascular spasm and blood clotting
