Midterm Bio 2

1. Transports gases and nutrients
2.Regulation of PH and osmosis
3.Maintenance of Body temperature.
4.Protection against foreign substances
5.Clot Formation

55% Plasma - 91 % water 7 % proteins
45 % formed elements

Liquid Part of Blood
Ions Nutrients Waste Products Gases
Regulates Substances - hormones, enzymes

Albumins - Viscosity, Osmotic Pressure, Buffer, Transports Fatty Acids, Free bilirubin, thyroid hormones

Globulins - Transports Lipids, Carbohydrates, Hormones, Ions, Antibodies

Fibrinogen - Blood Clotting

Contains Hemoglobin, Transports oxygen and carbon dioxide
1/3 Hemoglobin
2/3 Lipids
RBCs last 120 days in circulation

Protects body against microogranisms and remove dead cells and debris
Granulocytes - Cytoplasm contains large granules, have multi lobed nuclei. Has 3 distinctive types : Neutrophils, eosinophils, basophils

O

Form Platelet plugs, release chemicals necessary for blood clotting

Process of Blood Cell Production

7 % dissolved in plasma
23 % in combination with hemoglobin
70 % transported as bicarbonate ions produced as a result of combination of H20 and Co2 because of enzyme carbonic anhydrase found within RBCs

A hormone that stimulates RBC production. Produced by kindeys in response to low blood 02 levels

Broken down by macrophages into heme and globen chains
Globen chains of hemoglobin are broken down to amino acids and are metabolized or used to build new proteins

Ameboid - pseudopodia make them move like amoeba

Diapedesis - cells become thin, elongate and move either between or through endothelial cells of capillaries

Chemotaxis - attraction to and movement toward foreign materials or damaged cells

Secrete Lysozome
Accounts for 60-70 % of WBC

Enter tissues during inflammatory response.
prevelant in allergic reactions and parasitic infections
2-4 % of WBC

Inflammatory and allergic reactions
Produce histamine and heparin
Less than 1 % of the WBC population
